     BACKGROUND 
       [0002]    1. Technical Field 
         [0003]    Aspects of this document relate generally to telecommunication systems and techniques for transmitting data across a telecommunication channel. 
         [0004]    2. Background Art 
         [0005]    Since the advent of satellite communications, a recurring problem that continues to challenge the industry are Radio Frequency (RF) carriers transmitting on satellites and frequencies in transponders to which they are not assigned. As more satellites enter service and the geostationary arc fills, the problem becomes more acute as two degree spacing of the satellites becomes the norm. Improper operation and transmission of carriers is primarily due to human error and can result in service disruptions due to interference with the correctly assigned carriers. 
         [0006]    Currently, the majority of satellites do have beacons for alignment, however, these beacons typically comprise an unmodulated carrier that provides no information about the repeating relay other than its center frequency.

Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventors are fully aware that they can be their own lexicographers if desired. The inventors expressly elect, as their own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless they clearly state otherwise and then further, expressly set forth the “special” definition of that term and explain how it differs from the plain and ordinary meaning Absent such clear statements of intent to apply a “special” definition, it is the inventors&#39; intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims. 
         [0020]    The inventors are also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.

     DESCRIPTION 
       [0032]    This disclosure, its aspects and implementations, are not limited to the specific components, frequency examples, or methods disclosed herein. Many additional components and assembly procedures known in the art consistent with the transmission of identification via meta-data are in use with particular implementations from this disclosure. Accordingly, although particular implementations are disclosed, such implementations and implementing components may comprise any components, models, versions, quantities, and/or the like as is known in the art for such systems and implementing components, consistent with the intended operation. 
         [0033]    This disclosure relates to, but is not limited to, a method and system for providing information in the form of meta-data that uses spread spectrum technology to create a meta-carrier used to create a smart beacon for a repeating relay device. Particular implementations described herein are and may use, but are not limited to, Field-Programmable Gate Arrays (FPGA), digital signal processors, Application-Specific Integrated Circuits (ASIC), Programmable Integrated Circuits (PIC), or microprocessors. 
         [0034]    This disclosure further describes systems and methods for providing information in the form of meta-data that is embedded as a low-energy density meta-carrier into a repeating relay device for use by terrestrial, airborne and space-based operation. The smart beacon may utilize techniques known in the art for digital, analog and radio frequency design methodologies to enhance existing and future relay devices for use in identifying the relay. 
         [0035]    Aspects of this disclosure relate to methods and systems for creating a low-energy density meta-carrier for use as a smart beacon using spread spectrum spreading, modulation, transmission, reception, demodulation, despreading, decoding and processing of the meta-data that comprises the smart beacon. 
         [0036]    This disclosure relates to a method of embedding information regarding an electromagnetic transmission&#39;s origin. A need exists for a method of identifying satellite transponders to reduce uncertainty of carrier assignment. Therefore, a method of embedding information about the repeating relay within the repeating relay platform comprising a relay, transponder, or satellite is needed. Information about the repeating relay may be carried in the form of meta-data information and may contain, but is not limited to, ephemeris data, the name of the repeating relay, name of the owner, orbital location, center frequency, passband, and transponder electromagnetic (EM) polarization, etc. This meta-data eliminates ambiguity with regard to the satellite and transponder of operation. The methods and systems described herein allow a person of only moderate skill, for example, a person with only months of experience on earth station alignment techniques, to reliably align to the correct satellite and transponder assignment. 
         [0037]    Various implementations of this disclosure are intended to be employed for an EM emitting device, such as optical or Radio Frequency (RF) transmission equipment for point-to-point, point-to-multipoint and/or multipoint-to-multipoint for embedded information, an example of which is shown in  FIG. 1 . 
         [0038]    Methods for providing transmission information via meta-data may be accomplished by spreading a very low-data rate carrier (containing information about the desired carrier known as the “meta-data”) over a portion or the entire passband of the repeating relay&#39;s transponder or transponders. The low-data rate carrier may be spread, or as it is known in the art, “chipped,” with a direct sequence spread spectrum (DSSS) pseudo-random number (PRN) sequence to create a low energy meta-carrier that may be placed over a portion or entire passband of the repeating relay. This process of spreading the very low-data rate carrier and placing it over a portion of or the entire passband is shown in  FIGS. 2A-D . 
         [0039]    One novel aspect of the disclosed methods and systems may involve using a large spreading factor that results in spreading the meta-carrier&#39;s energy over a significantly large bandwidth, of many orders of magnitude, many times the original meta-data&#39;s rate. The dispersion of energy may result in a miniscule amount of noise being added to the transponder&#39;s spectrum. Additionally, the act of spreading the meta-carrier information by many orders of magnitude (hundreds, thousands or even millions of times) may result in tremendous processing gain that can be realized to extract and separate the meta-carrier&#39;s meta-data from the received transponder even when the transponder is used for transmission of information carriers. The meta-carrier may be placed on a single transponder or a plurality of transponders, if available, and the meta-data may be extracted by a receiving device from the embedded meta-carrier contained in the passband of the transponder. The spread spectrum meta-carrier may be placed over a portion or the entire passband of the transponder. 
         [0040]    Additionally, another novel aspect of one or more of the disclosed methods and systems may involve the embedded meta-carrier being used as a smart beacon to identify the repeating relay. The large processing gain, as a result of spreading the meta-data&#39;s meta-carrier over a portion or the entire passband of the relay&#39;s transponder or transponders, may be utilized to separate the meta-carrier energy from the information carriers being supported by the transponders at the receiving device. The smart beacon may be utilized on a single transponder of a chosen EM configuration, two orthogonal/opposite EM configurations (horizontal verses vertical or clockwise verses counter-clockwise), and/or any combination of partial or all transponders of EM configurations, and may contain similar or different meta-data for each transponder. 
         [0041]    Particular implementations of insertion of transmission of meta-data information over a low-energy density meta-carrier for use as a smart beacon are disclosed herein and may be specifically employed in satellite communications systems. However, as will be clear to those of ordinary skill in the art from this disclosure, the principles and aspects disclosed herein may readily be applied to any electromagnetic (IF, RF and optical) communications system, such as terrestrial or airborne broadcast networks without undue experimentation. 
         [0042]      FIG. 1  depicts a satellite-based repeating relay being utilized by many devices that may both transmit and receive to/from the repeating relay. More specifically,  FIG. 1  illustrates a particular implementation of a satellite transmission system comprised of earth stations  100  such as the one shown in  FIG. 6 , communicating over a repeating relay  110  such as those shown in  FIGS. 3-5 . The earth stations  100  and the repeating relay  110  may be separated by tens, hundreds or thousands of miles. In particular embodiments, the remote relay may operate over one or more of L-Band, S-Band, C-Band, X-Band, Ku-Band and/or Ka-Band, or any other suitable communication band. 
         [0043]    A repeating relay  110  may comprise a single input frequency that may be frequency up and/or down-converted and/or power amplified and re-transmitted. In the simplest configuration, the input to output of the relay  110  comprises the simplest form of a transponder. The “bandwidth” of a relay is known in the art as the “passband.” The passband of a relay is the range between the lowest and highest frequency that may be passed through the repeating relay&#39;s transponder. 
         [0044]    As shown in  FIGS. 2A-D , using the attributes of spread spectrum technology, a low-data rate data stream may be spread using DSSS spreading with a PRN sequence resulting in a low-energy density carrier that may be placed over a portion or entire passband of a transponder or transponders of a repeating relay.  FIGS. 2A-D  illustrate the concept of the passband shown in the dashed lines with a center frequency as fc. The passband includes the lowest frequency (shown to the left side of fc) to the highest frequency (shown to the right side of fc), such that all frequencies between the two extremes are known as the passband. In the art, the passband may be defined as the point where the half power or by non-limiting example, 3 Decibel (3 dB) of power is cut off (or known as roll off). The operation of particular embodiments of the disclosed methods may use a portion or the entire bandwidth in the 3 dB passband of the transponder. One of ordinary skill in the art will recognize that this disclosure is not limited to a 3 dB passband and as such, any appropriate passband may be used. A transponder may be utilized for the reception of user data in the form of a modulated carrier by modulation techniques know in the art, but not limited to, Amplitude Modulation (AM), Frequency Modulation (FM), Phase Shift Keying (PSK), Frequency Shift Keying (FSK), etc. The transponder may be configured to accept any modulated carrier or carriers that fall into the passband of the transponder and to frequency convert (up and/or down) and/or amplify the carriers and relay them from the repeating relay. 
         [0045]    In the described methods, spread-spectrum technology, such as but not limited to direct sequence spread-spectrum (DSSS) technology may be utilized to spread low-data rate information, known as meta-data. This meta-data may contain, but is not limited to, ephemeris data, the name of the repeating relay, name of the owner, orbital location, center frequency, passband, and transponder electromagnetic (EM) polarization, etc. The meta-data may then be spread via a spread spectrum technique known in the art as chipping which may include using a predetermined PRN sequence that may result in each bit of the meta-data being spread by hundreds, thousands or even millions of times. The act of spreading the low-data rate meta-data may result in a meta-carrier that may be comprised of many hundreds, thousands or even millions of chips of each bit of information. Chipping a meta-data stream with a PRN sequence may result in a gain known in the art as “processing gain.” The processing gain is the linear ratio of the chipping rate divided by the meta-data rate, and is commonly called the spread factor. The processing gain is typically known in terms of gain in decibels, and is calculated as 10*Log(Spread Factor). 
         [0046]    As a non-limiting example, a 10-bit per second meta-data carrier may be spread over a 36 MHz transponder. The 36 MHz transponder may provide support for a 36 Mega-chip per second (36 Mcps) carrier, resulting in the spread factor of 36,000,000/10 or 3,600,000. Expressed in terms of processing gain, the processing gain due to spreading may be 10*Log(3,600,000) or 65.56 dB. The meta-carrier could be embedded into the noise floor of the transponder in a manner that has little to no impact to the user data carriers being supported by the transponder. The processing gain of 65.56 dB may allow ample separation between the user data carriers, which appear as noise to the meta-carrier, such that the meta-carrier may be extracted using a receiver such as that shown in  FIG. 7 . 
         [0047]    As a second non-limiting example, a 10-bit per second meta-data carrier may be spread over a 54 MHz transponder. The 54 MHz transponder may provide support for a 54 Mega-chip per second (54 Mcps) carrier, resulting in the spread factor of 54,000,000/10 or 5,400,000. Expressed in terms of processing gain, the processing gain due to spreading may be 10*Log(5,400,000) or 67.32 dB. The meta-carrier could be embedded into the noise floor of the transponder in a manner that has little to no impact to the user data carriers being supported by the transponder. The processing gain of 67.32 dB may allow ample separation between the user data carriers, which appear as noise to the meta-carrier, such that the meta-carrier may be extracted using a receiver such as that shown in  FIG. 7 . 
         [0048]    As yet another non-limiting example, a 20-bit per second meta-data carrier may be spread over a 72 MHz transponder. The 72 MHz transponder may provide support for a 72 Mega-chip per second (72 Mcps) carrier, resulting in the spread factor of 72,000,000/20 or 3,600,000. Expressed in terms of processing gain, the processing gain due to spreading may be 10*Log(3,600,000) or 65.56 dB. The meta-carrier may be embedded into the noise floor of the transponder in a manner that results in little to no impact to the user data carriers being supported by the transponder. The processing gain of 65.56 dB may allow ample separation between the user data carriers, which appear as noise to the meta-carrier, such that the meta-carrier may be extracted using a receiver such as that shown in  FIG. 7 . 
         [0049]      FIGS. 3-5  demonstrate multiple configurations of repeating relays and show how each may be configured to provide a low-energy density meta-carrier that contains meta-data for a smart beacon using implementations of the described methods and systems. 
         [0050]    In the simplest embodiment of the method, the spread spectrum meta-carrier may be created at a transmission station and transmitted to the remote relay as shown in  FIG. 3  and embedded into one or a plurality of transponders. For each transponder to support the embedded carrier, for particular implementations of the methods described, a meta-carrier is transmitted for every transponder. 
         [0051]      FIG. 3  demonstrates existing repeater relay technology used in the art where a meta-carrier containing meta-data may be transmitted to a relay repeater where the low-energy meta-carrier may be combined with the data carriers being supported by the repeating relay. The repeating relay of  FIG. 3  has no onboard processing of the meta-carriers other than to relay from the input (receive antenna)  300 , separate in the Orthogonal Mode Transducer (OMT)  310 , Bandpass Filter (BPF)  320 , amplify via a Low-Noise Amplifier (LNA)  330 , multiplex via a multiplexer  340 , frequency convert using a frequency converter  350 , linearize using a linearizer  360 , amplify with an amplifier  370 , multiplex to the proper EM polarization configuration using a multiplexer  380  and feed to the OMT  310  to the transmit antenna  390  feed for relay. The configuration of the transponders of the repeating relay may be comprised of a single transponder or a plurality of EM transponders with or without overlapping frequencies such as the horizontal and/or left-hand circular Type 1 transponders  800  and the vertical and/or right-hand circular Type 2 EM transponders  810  as shown in  FIG. 8  which depicts a particular embodiment of a repeating relay with transponders with common and overlaid frequencies with a plurality of EM polarization configurations. In the particular embodiment shown in  FIG. 8 , no additional hardware (analog or digital) may be required to be added to the repeating relay. 
         [0052]    In a second embodiment, the meta-carrier may be transmitted as a spread spectrum carrier that may be created at a transmission station  100  and transmitted to the remote relay  110  as shown in  FIG. 4 . The carrier may be extracted by the onboard beacon extraction device  400  and it may be routed to the beacon injection device  410  where the meta-carrier may be embedded into one or a plurality of transponders. In this embodiment, additional hardware (analog and/or digital) may be required to be added to the repeating relay  110 . 
         [0053]    In a third embodiment, the meta-carrier may be transmitted as a non-spread spectrum carrier that may be created at a transmission station  100  and transmitted to the remote relay as shown in  FIG. 4  and extracted by the onboard beacon extraction device  400 . The non-spread spectrum carrier may then be spread on board the repeater relay  110  and it may be routed to the beacon injection device  410  where the meta-carrier may be embedded into one or a plurality of transponders. In this embodiment, additional hardware (analog and/or digital) may be required to be added to the repeating relay  110 . 
         [0054]    In a fourth embodiment, the meta-data may be transmitted as a spread spectrum or non-spread spectrum carrier that may be created at a transmission station  100  and transmitted, periodically or one time, to the remote relay as shown in  FIG. 5 . The meta-data may be extracted by the onboard beacon extraction device  400  and sent to the beacon processor  500 . The beacon processor  500  may store the meta-data and perform processing on the meta-data. The meta-data may be altered by the beacon processor  500  in a fashion that makes the information unique to each transponder or it may be the same information sent to each transponder. The meta-data may then be spread and modulated on the repeater relay  110  and sent to the beacon injection unit  410  for delivery to the output multiplexer  380 . In this embodiment, additional hardware (analog and/or digital) may be required to be added to the repeating relay  110 . 
         [0055]    In a fifth embodiment, the meta-data may be retained in the beacon processor  500  and loaded one time at the creation of the repeater relay  110  as shown in  FIG. 5 . The meta-data may be sent by the beacon processor  500  in a fashion that makes the information unique to each transponder or it may be the same information sent to each transponder. The meta-data may then be spread and modulated on the repeater relay  110  and sent to the beacon injection unit  410  for delivery to the output multiplexer  380 . In this embodiment, additional hardware (analog and/or digital) may be required to be added to the repeating relay  110 . 
         [0056]    One of ordinary skill in the art will recognize that the methods disclosed herein may rely on the use of spread spectrum technology but are not limited as such and may therefore utilize any methods of electromagnetic or optical transmission techniques using any known transmission method to transmit meta-data to a repeating relay. 
         [0057]      FIG. 6  shows a diagram of a receiving site that utilizes the described method for receiving both user data and the meta-carrier containing the meta-data information about the repeating relay  110 . The receiving station  630  may comprise an antenna reflector that may be pointed to the repeating relay  110  as depicted in  FIG. 6 . The antenna reflector may be focused to a feed horn  600  where the received carrier from the repeater relay  110  may be focused and the OMT  640  separates the carrier into the proper polarizations. A Low Noise Block (LNB) amplifier  610  may be comprised of an LNA and down-converter for converting the radio frequency (RF) signal to an Intermediate Frequency (IF). In the art, the LNB amplifier  610  converts the RF (L-Band, S-Band, C-Band, X-Band, Ku-Band, Ka-Band, etc.) to IF at 70/140 MHz (50 MHz to 180 MHz) or L-Band (950 MHz to 2,150 MHz). The output of the LNB amplifier  610  may then be sent to a coaxial connection  650  to the receiving device where the signal comprised of the low-energy meta-carrier and user data carriers. 
         [0058]      FIG. 7  shows a block diagram of the receiving device using the disclosed methods where the low-energy density meta-carrier is received and extracted from the passband of the received transponder, de-spread, demodulate and decode and provided to the user as meta-data. The receiver section  700  may perform the appropriate receiver functions such as level setting via an Automatic Gain Control (AGC) and then Spread Spectrum de-spreading may be performed by a spread-spectrum despreader  710 . The despread meta-carrier may contain the meta-data for use by a receiving device to confirm, but is not limited to, information about a repeating relay&#39;s source to include information, but not limited to, ephemeris data, the name of the repeating relay, name of the owner, orbital location, center frequency, passband, and transponder electromagnetic (EM) polarization, etc. 
         [0059]    The following provides non-limiting examples of particular implementations and embodiments of transmission of identification via meta-data for repeating relays using spread-spectrum technology techniques: 
       Example 1 
       [0060]    A space-based satellite relay may be configured to receive earth-based carriers and relay the carriers back to the earth. The carrier(s) may be received, combined, amplified and combined with a low data rate meta-data carrier. A satellite earth station transmits the meta-data via a spread spectrum carrier to a satellite with repeating relays (transponders). One carrier is transmitted towards the satellite. The meta-data in this carrier can contain (but is not limited to) the following information; a) satellite operator, b) satellite name, c) orbital location, d) transponder numbers and associated center frequency assignments and electromagnetic polarizations. 
       Example 2 
       [0061]    A space-based satellite relay may be configured to receive earth-based carriers and relay the carriers back to the earth. The carrier(s) may be received, combined, amplified and combined with a low data rate meta-data carrier. A satellite earth station transmits the meta-data via a spread spectrum carrier to a satellite with repeating relays (transponders). One carrier may be transmitted towards the satellite for each electromagnetic polarization (one horizontal and one vertical or one clockwise and one counterclockwise). The meta-data in this carrier can contain (but is not limited to) the following information: a) satellite operator, b) satellite name, c) orbital location, d) transponder numbers and associated center frequency assignments and electromagnetic polarizations. 
       Example 3 
       [0062]    A space-based satellite relay may be configured to receive earth-based carriers and relay the carriers back to the earth. The carrier(s) may be received, combined, amplified and combined with a low data rate meta-data carrier. A satellite earth station transmits the meta-data via a spread spectrum carrier to a satellite with repeating relays (transponders). One carrier may be transmitted towards the satellite for each transponder of one electromagnetic polarization (one horizontal or one vertical or one clockwise or one counterclockwise). The meta-data in this carrier can contain (but is not limited to) the following information; a) satellite operator, b) satellite name, c) orbital location, d) transponder numbers and associated center frequency assignments and electromagnetic polarizations. 
       Example 4 
       [0063]    A space-based satellite relay may be configured to receive earth-based carriers and relay the carriers back to the earth. The carrier(s) may be received, combined, amplified and combined with a low data rate meta-data carrier. A satellite earth station transmits the meta-data via a spread spectrum carrier to a satellite with repeating relays (transponders). One carrier may be transmitted towards the satellite for each transponder of each electromagnetic polarization (one horizontal or one vertical or one clockwise or one counterclockwise). Non-limiting examples of meta-data in this carrier include a) satellite operator, b) satellite name, c) orbital location, d) transponder numbers and associated center frequency assignments and electromagnetic polarizations. 
       Example 5 
       [0064]    A satellite earth station may be configured to operate at an assigned center frequency, symbol rate and polarization to a satellite at a geo-equatorial location, polarization and frequency. For this example, the earth station may not be pointed to the proper satellite and begins transmission. This results in the wrong satellite being illuminated. In the event the improperly radiated satellite has the frequency assigned for use not for this carrier, the result may be an outage due to energy being injected into the satellite&#39;s transponder that may then be re-transmitted along with the proper carrier to receiving devices. The method may allow one to detect, resolve and process the meta-data of the wrong satellite, thus providing information to the interfering earth station, alerting the operator of the earth station as to its improperly configured carrier. 
       Example 6 
       [0065]    In particular implementations of the system described in Examples 1-4, a carrier may be uplinked to as part of an ad-hoc service and the service may only be required for a short duration. As an aid to the link provider, the reception of the meta-data carrier may be used as confirmation that the transmitter may be set up on the proper transponder. 
       Example 7 
       [0066]    In particular implementations of the system described in Examples 1-4, a satellite earth station may be configured to operate a carrier at an assigned center frequency, symbol rate and polarization to a satellite at a particular frequency and geo-equatorial location. For this example if the earth station is pointed to the proper satellite but has an incorrect carrier center frequency, and begins transmission, this results in the wrong frequency of a satellite transponder being illuminated. In this event, the improperly radiated satellite transponder may have the frequency assigned for use, but not for this carrier. The result may be an outage due to energy being injected into the satellite&#39;s transponder that may then be re-transmitted along with the proper carrier. The method may allow one to detect, resolve and process the satellite&#39;s meta-data carrier, thus providing information to the operator of the earth station about their improperly configured carrier. 
       Example 8 
       [0067]    In particular implementations of the system described in Examples 1-4, a satellite earth station may be configured to operate a carrier at an assigned center frequency, symbol rate and polarization to a satellite at a particular frequency and geo-equatorial location. For this example, if the earth station is pointed to the proper satellite but has an incorrect carrier center frequency, and begins transmission, this results in the wrong frequency of a satellite transponder being illuminated. In this event, the improperly radiated satellite transponder does not have the frequency assigned for use. The result may be a spurious carrier whose source may be difficult to identify. The method may allow one to detect, resolve and process the satellite&#39;s meta-data carrier, thus providing information to the operator of the earth station about their improperly configured carrier. 
       Example 9 
       [0068]    In particular implementations of the system described in Examples 1-4, a satellite earth station may be configured to operate a carrier at an assigned center frequency, symbol rate and polarization to a satellite at a particular frequency and geo-equatorial location. For this example, if the earth station is pointed to the proper satellite and has a correct carrier center frequency but the wrong symbol rate in excess of the assigned symbol rate and begins transmission, this results in the satellite transponder being illuminated with a carrier that crosses over into an adjacent channel. In this event, the improperly radiated satellite transponder has multiple carriers using the same frequency. The result may be an outage potentially of both adjacent carriers due to energy being injected into the satellite&#39;s transponder that may then be re-transmitted along with the adjacent carrier. The method may allow one to detect, resolve and process the satellite&#39;s meta-data carrier, thus providing information to the operator of the earth station about their improperly configured carrier. 
       Example 10 
       [0069]    In particular implementations of the system described in Examples 1-4, a satellite earth station may be configured to operate a carrier at an assigned center frequency, symbol rate and polarization to a satellite at a particular frequency and geo-equatorial location. For this example if the earth station is pointed to the proper satellite, has a correct carrier center frequency, but an incorrect polarization and begins transmission, this results in the wrong frequency of a satellite transponder being illuminated. In this event, the improperly radiated satellite transponder has the frequency assigned for use, but not for this carrier. The result may be an outage due to energy being injected into the satellite&#39;s transponder that may then be re-transmitted along with the proper carrier. The method may allow one to detect, resolve and process the satellite&#39;s meta-data carrier, thus providing information to the operator of the earth station about their improperly configured carrier. 
       Example 11 
       [0070]    In particular implementations of the system described in Examples 1-4, a satellite earth station may be configured to operate a carrier at an assigned center frequency, symbol rate and polarization to a satellite at a particular frequency and geo-equatorial location. For this example, if the earth station is pointed to the proper satellite, has a correct carrier center frequency, but an incorrect polarization and begins transmission, this results in the wrong frequency of a satellite transponder being illuminated. In this event, the improperly radiated satellite transponder does not have the frequency assigned for use. The result may be a spurious carrier whose source is difficult to identify. The method may allow one to detect, resolve and process the satellite&#39;s meta-data carrier, thus providing information to the operator of the earth station about their improperly configured carrier. 
       Example 12 
       [0071]    An airborne relay is configured to receive earth-based carriers and relay the carriers back to the earth. The carrier(s) may be received, combined, amplified and combined with a low-data rate carrier containing meta-data, including but not limited to, information regarding the airborne relay&#39;s assigned location, owner, transponder identification, operating frequency, etc. For an airborne system, the bandwidth may be spread over one or many transponders. 
       Example 13 
       [0072]    A terrestrial relay may be configured to receive terrestrial or airborne carriers and relay the carriers to the same or different geographic location(s). The carrier(s) may be received, combined, amplified and combined with a low-data rate meta-data carrier containing, but not limited to, information regarding the relay&#39;s assigned location, owner, operating frequency, etc. For a terrestrial relay system, the bandwidth may be spread over one or multiple frequency allocations. 
         [0073]    In places where the description above refers to particular implementations of telecommunication systems and techniques for transmitting data across a telecommunication channel, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other to telecommunication systems and techniques for transmitting data across a telecommunication channel.
