## Background
BACKGROUND INFORMATION
1. Field:
The present disclosure relates generally to aircraft and, in particular, to unmanned aerial vehicles. Still more particularly, the present disclosure relates to a method and apparatus for operating unmanned aerial vehicles in different locations.
2. Background:
An unmanned aerial vehicle (UAV) is an aircraft that flies without human operators being present in the aircraft. Unmanned aerial vehicles may be controlled from a remote location. At this remote location, a human operator or a program executed by a computer generates commands for the unmanned aerial vehicle. Unmanned aerial vehicles also may be controlled using a program running on a computer or other controller on the unmanned aerial vehicle.
Unmanned aerial vehicles are used for a number of different purposes. Currently, the largest use is for military applications. Unmanned aerial vehicles may be used to perform missions that may include, for example, without limitation, reconnaissance missions, attack missions, and/or other suitable types of missions. Unmanned aerial vehicles also may be used in a number of civilian applications. For example, without limitation, unmanned aerial vehicles may be used to perform surveying, firefighting, and/or other suitable types of missions.
Unmanned aerial vehicles may come in a number of different sizes and shapes. Unmanned aerial vehicles may, for example, take the form of fixed wing aircraft, helicopters, and/or ornithopters. For example, without limitation, an unmanned aerial vehicle may take the form of an airplane, a helicopter, or some other suitable type of device capable of flying. The size of an unmanned aerial vehicle may vary greatly. For example, an unmanned aerial vehicle may have a wing span from about a few inches to about 200 feet, depending on the type of unmanned aerial vehicle.
Smaller unmanned aerial vehicles are referred to as micro air vehicles. These types of air vehicles may be configured to be carried by a person and may be launched by the person. For example, the micro air vehicles may be launched by the person throwing the micro air vehicles in the air. The small size of these types of air vehicles allows this type of launching method to provide sufficient velocity for these air vehicles to begin flight.
The size of unmanned aerial vehicles has been reduced in part because of a reduction in the sizes of sensors, motors, power supplies, and controllers for these types of vehicles.
These reduced sizes and reductions in cost make it desirable to operate these vehicles in large numbers. For example, micro air vehicles (MAVs) may be operated in numbers that are about the size of a squad or platoon, as compared to operating one or two larger unmanned aerial vehicles. This type of operation increases the monitoring that can be performed for a particular area.
These types of unmanned aerial vehicles also may land on a perch, a building, or another location. In this manner, a micro air vehicle may monitor a particular location without having to continue flight. The micro air vehicle may be repositioned if the area of interest changes.
For example, a micro air vehicle may land on a building in a city or town. The micro air vehicle may monitor a particular road or building in the city.
Micro air vehicles, however, have limitations with their smaller size, as compared to larger unmanned aerial vehicles. For example, the processing power and data transmission ranges may be more limited for micro air vehicles, as compared to larger unmanned aerial vehicles. Further, the range of these micro air vehicles may be shorter, as compared to the larger unmanned aerial vehicles.
Therefore, it would be advantageous to have a method and apparatus that takes into account one or more of the issues discussed above, as well as other possible issues.

DETAILED DESCRIPTION
The different advantageous embodiments recognize and take into account a number of considerations. For example, the different advantageous embodiments recognize and take into account that unmanned aerial vehicles may be more susceptible to environmental conditions as the size of the unmanned aerial vehicles decreases. For example, a micro air vehicle having a wing span of about 13 inches and a weight of about six ounces may be more susceptible to wind gusts, rain, hail, and/or other conditions, as compared to an unmanned aerial vehicle having a wing span of about 84 feet and a weight of about 7,000 pounds.
The different advantageous embodiments also recognize and take into account that having human operators launch, retrieve, and/or maintain unmanned aerial vehicles during a mission may be time-consuming and/or expensive. The different advantageous embodiments also recognize and take into account that with the use of human operators, the mission being performed by the unmanned aerial vehicles may be more likely detected when such detection is undesirable.
Further, as the size of an unmanned aerial vehicle decreases, the range and complexity of the components in the unmanned aerial vehicle also may decrease. As a result, more maintenance of these types of unmanned aerial vehicles may be required.
Thus, the different advantageous embodiments provide a method and apparatus for performing a mission using unmanned aerial vehicles. In one advantageous embodiment, an apparatus comprises a platform, a battery system, a power generation system, a number of charging stations, and a controller. The platform is configured to house a number of unmanned aerial vehicles. The battery system is configured to store electrical energy in the form of chemical energy.
The battery system is configured to generate electrical current as needed to provide power to the various components in the apparatus. The power generation system is connected to the battery system. The power generation system is configured to generate electrical energy from an environment in which the platform is located. The power generation system is also configured to store the electrical energy in the battery system. The number of charging stations is connected to the battery system in which each charging station in the number of charging stations is configured to charge an unmanned aerial vehicle. The controller is configured to receive sensor data from a number of unmanned aerial vehicles and generate information from the data and send the information to a remote location.
With reference now to FIG. 1, an illustration of an unmanned aerial vehicle environment is depicted in accordance with an advantageous embodiment. Unmanned aerial vehicle environment 100 includes unmanned aerial vehicle base station 102, unmanned aerial vehicle base station 104, and unmanned aerial vehicle base station 106.
In this illustrative example, unmanned aerial vehicle base station 102 is located on rooftop 108 of building 110 within town 112. Unmanned aerial vehicle base station 104 is associated with vehicle 114. A first component may be considered to be associated with a second component by being secured to the second component, bonded to the second component, fastened to the second component, and/or connected to the second component in some other suitable manner. The first component also may be connected to the second component by a third component. The first component may be considered to be associated with the second component by being formed as part of and/or an extension of the second component.
Unmanned aerial vehicle base station 106 is located on power lines 116. Unmanned aerial vehicle base stations 102, 104, and 106 may be deployed in a number of different ways. Unmanned aerial vehicle base station 102 may be dropped off by helicopter on rooftop 108. The location of unmanned aerial vehicle base station 102 on rooftop 108 may result in unmanned aerial vehicle base station 102 being less observable. Further, this location may provide a better line of sight between unmanned aerial vehicle base station 102 and communication arrays. In this manner, the range at which unmanned aerial vehicle base station 102 may communicate with unmanned aerial vehicles may be increased.
Unmanned aerial vehicle base station 104 is associated with vehicle 114. By being associated with vehicle 114, unmanned aerial vehicle base station 104 may be moved periodically or constantly. This type of deployment may reduce the discoverability of unmanned aerial vehicle base station 104. Further, by providing mobility to unmanned aerial vehicle base station 104, greater flexibility may be present for performing missions. In addition, unmanned aerial vehicle base station 104 may be removed from vehicle 114 and placed on the ground or in some other suitable location.
Unmanned aerial vehicle base station 106 may be deployed onto power lines 116 by being dropped by a helicopter, on a parachute, or some other suitable mechanism. Unmanned aerial vehicle base station 106 may be less observable on power lines 116. As depicted, unmanned aerial vehicles, such as unmanned aerial vehicles 118, 120, 122, 124, 126, 128, 130, 132, 134, 136, and 138 may operate from unmanned aerial vehicle base stations 102, 104, and 106.
In these illustrative examples, unmanned aerial vehicle base stations 102, 104, and 106 provide a base from which the different unmanned aerial vehicles may transmit data, receive instructions, recharge, be stored, and/or perform other operations.
Additionally, unmanned aerial vehicles may travel from base station to base station. In other words, unmanned aerial vehicle base stations 102, 104, and 106 may provide a network to extend the range of unmanned aerial vehicles. Having multiple unmanned aerial vehicle base stations also may provide backup in case one unmanned aerial vehicle base station malfunctions or fails to perform as needed.
As can be seen in this depicted example, unmanned aerial vehicle base stations 102, 104, and 106 may be placed in locations where detection of those base stations may be reduced. These locations may include other locations other than those illustrated in this particular example. For example, unmanned aerial vehicle base stations 102, 104, and 106 may be placed in trees, in brush, and/or in other suitable locations.
The unmanned aerial vehicles may be used to perform a number of different missions in unmanned aerial vehicle environment 100. In this illustrative example, the unmanned aerial vehicles may monitor for undesired activity. For example, the undesired activity may be the placement of an improvised explosive device in roadway 140. In another illustrative example, the unmanned aerial vehicles may monitor for movement of vehicles or people.

The type of micro air vehicles launched in this example may be based on data to be collected at a ground station in some illustrative examples.
With reference now to FIG. 20, an illustration of a flowchart of a process for operating an unmanned aerial vehicle base station is depicted in accordance with an advantageous embodiment. The process in FIG. 20 may be implemented using unmanned aerial vehicle base station 200 and number of unmanned aerial vehicles 214 in FIG. 2.
The process begins by moving an unmanned aerial vehicle to a charging station in a number of charging stations for an unmanned aerial vehicle base station (operation 2000). In these examples, the unmanned aerial vehicle base station comprises a platform configured to house a number of unmanned aerial vehicles, a battery system configured to store electrical energy, a power generation system connected to the battery system and configured to generate the electrical energy stored in the battery system, the number of charging stations connected to the battery system, and a controller connected to the battery system.
The controller is configured to receive sensor data from the number of unmanned aerial vehicles, generate information from the sensor data, and send the information to a remote location. The power generation system is configured to generate electrical energy from an environment in which the platform is located. Each charging station in the number of charging stations is configured to charge the number of unmanned aerial vehicles.
The unmanned aerial vehicle is charged at the charging station (operation 2002). The unmanned aerial vehicle is flown to a location after charging the unmanned aerial vehicle (operation 2004). The sensor data is sent to the controller (operation 2006), with the process terminating thereafter. In these illustrative examples, the process illustrated in FIG. 20 may be performed each time the unmanned aerial vehicle needs to be recharged.
With reference now to FIG. 21, an illustration of a flowchart of a process for processing sensor data is depicted in accordance with an advantageous embodiment. The process in FIG. 21 may be implemented using unmanned aerial vehicle base station 200 in FIG. 2.
The process begins by receiving sensor data from an unmanned aerial vehicle (operation 2100). The process adds metadata to the sensor data (operation 2102). This metadata may be, for example, without limitation, an identification of the unmanned aerial vehicle submitting the data, a location of the unmanned aerial vehicle, a time stamp, and/or other suitable information. In some advantageous embodiments, this operation may be optional if the unmanned aerial vehicle provides this information in the sensor data.
The process then stores the sensor data and the metadata (operation 2104), with the process then returning to operation 2100 to receive more sensor data from the unmanned aerial vehicle.
With reference now to FIG. 22, an illustration of a flowchart for processing sensor data is depicted in accordance with an advantageous embodiment. The process illustrated in FIG. 22 is an example of a process that may be implemented in an unmanned aerial vehicle, such as unmanned aerial vehicle 700 in FIG. 7. In particular, this process may be implemented in processor unit 716 in FIG. 7. In some advantageous embodiments, this process may be implemented in unmanned aerial vehicle base station 200 using controller 210 in FIG. 2.
The process begins by receiving sensor data from the sensor system (operation 2200). This sensor data may be, for example, an image or video stream. A determination is made as to whether the sensor data is of interest (operation 2202). This determination may be made on the unmanned aerial vehicle and/or at the unmanned aerial vehicle base station. This determination may be made in a number of different ways. For example, the unmanned aerial vehicle may be programmed to look for a particular object, such as a particular vehicle type with a particular color. This information may be part of the mission programmed into the unmanned aerial vehicle.
In other advantageous embodiments, this determination may be made by comparing the image with a prior image from a prior flyover of the location. For example, a change in pixels between the current image and a prior image of the same road may indicate that the sensor data is sensor data of interest.
If the sensor data is sensor data of interest, the sensor data is tagged (operation 2204). In this example, some sort of indicator may be added to the sensor data to identify the image as one of interest. In addition, other information may be added including, for example, an identification of the unmanned aerial vehicle, the location at which the image was taken, and/or the attitude and relative position of the unmanned aerial vehicle relative to the location where the image was taken.
The process then stores the sensor data (operation 2206), with the process terminating thereafter. With reference again to operation 2202, if the sensor data is not sensor data of interest, the process may add metadata to the image (operation 2208). This metadata may include, for example, metadata as described above, with respect to operation 2204. The process then proceeds to operation 2206.
In some advantageous embodiments, the information may also be transmitted to the unmanned aerial vehicle base station from the unmanned aerial vehicle instead of being stored on the unmanned aerial vehicle, depending on the particular implementation. In some advantageous embodiments, if the sensor data is not of interest, the sensor data may be discarded.
With reference now to FIG. 23, an illustration of a flowchart for processing sensor data to form information is depicted in accordance with an advantageous embodiment. The process illustrated in FIG. 23 may be implemented in unmanned aerial vehicle base station 200 in FIG. 2. In particular, the process may be implemented in controller 210 in FIG. 2. This process may be used by controller 210 to process data as the data is received from the unmanned aerial vehicle. In other advantageous embodiments, this processing of data may be performed at a later time.
The process begins by selecting an unprocessed portion of sensor data (operation 2300). The size of the unprocessed portion of sensor data may vary, depending on the particular implementation. For example, the unprocessed portion may be a single image or may be several minutes of video data. The process determines whether the portion of data is of interest (operation 2302). This operation may be performed using various processes or programs. For example, processes looking for changes in images that indicate the presence of improvised explosive devices may be used. The initial data flagged by the unmanned aerial vehicle can be processed to determine whether the change indicates that an improvised explosive device may be present.
Further, processes such as optical moving target indications used to find vehicles also may be used in this operation. Of course, other processes may be used, depending on the particular data that is desired to be identified.
If the portion of data is of interest, the process tags the portion of data as being data of interest (operation 2304). Thereafter, the process stores the portion of data (operation 2306). A determination is made as to whether additional unprocessed portions of data are present (operation 2308). If additional unprocessed portions of data are present, the process returns to operation 2300. Otherwise, the process terminates.
With reference again to operation 2302, if the portion of data is not of interest, the process then proceeds to operation 2306 as discussed above. In some advantageous embodiments, in operation 2306, the process may also transmit the data over a communications link to a remote location in addition to or in place of storing the data.
With reference now to FIG. 24, an illustration of a flowchart of a process for sending information to an unmanned aerial vehicle is depicted in accordance with an advantageous embodiment. The process illustrated in FIG. 24 may be implemented in unmanned aerial vehicle base station 200 in FIG. 2. In particular, the process may be implemented in controller 210 in FIG. 2.
The process begins by identifying the location of the unmanned aerial vehicle base station (operation 2400). Thereafter, the process generates differential global positioning system information (operation 2402). Differential global positioning system information is information that may be used by the unmanned aerial vehicle to identify the location of the unmanned aerial vehicle based on the location of the unmanned aerial vehicle base station.
The process then transmits the differential global positioning system information to the number of unmanned aerial vehicles (operation 2404), with the process terminating thereafter.
With reference now to FIG. 25, an illustration of a flowchart of a process for changing a mission is depicted in accordance with an advantageous embodiment. The process illustrated in FIG. 25 may be implemented in unmanned aerial vehicle base station 200 in FIG. 2 and in particular, in controller 210 in FIG. 2.
The process begins by receiving weather data (operation 2500). A determination is made as to whether changes to the mission are needed based on the weather data (operation 2502). This determination may include, for example, without limitation, whether different flight paths should be used to take advantage of tail winds or to avoid undesirable conditions.
Additionally, this determination in operation 2502 also may include changing the mission, such as recalling the number of unmanned aerial vehicles if the analysis determines that the weather conditions may affect the capability of the unmanned aerial vehicles to operate or return to the unmanned aerial vehicle base station.
If changes in the mission are needed, the changes are transmitted to the unmanned aerial vehicles (operation 2504), with the process terminating thereafter. With reference again to operation 2502, if changes are not needed, the process terminates.
