[^1]: THE ANTENNA BEAM WIDTHS ARE: (A) S-BAND = 7.6° AND (B) Ku-BAND =
    1.2°. TO AVOID MAIN BEAM OR FIRST SIDE LOBE ILLUMINATION OF THE CORE
    AREA OF DARK SECTOR (BUILDING COMPLEX WITH MOST EXPERIMENTS), THE
    LINE OF AZIMUTH FROM THE SPTR ANTENNA TO THE TDRS F1 SATELLITE AT
    49° W LONGITUDE MUST AVOID CO-INCIDENCE WITH LINE OF AZIMUTH FROM
    THE ANTENNA TO THE DARK SECTOR CORE COMPLEX. SPIREX WAS USED AS A
    REFERENCE. A 5° AZIMUTH (LONGITUDE) MARGIN IS PRUDENT TO ALLOW FOR
    S-BAND HALF-BEAM WIDTH.

[^2]: SOUTH POLE SCIENCE USERS OF DARK SECTOR HAVE BEEN CANVASSED AND
    AGREE THAT IT IS UNDESIRABLE, POTENIALLY HARMFUL, TO ILLUMINATE THE
    CORE DARK SECTOR AREA WITH THE TRANSMISSIONS. SOUTH POLE SCIENCE
    USERS DO NOT WANT BEAM SPILLAGE INTO CENTRAL AREA.

[^3]: PRACTICAL OPERATING EXPERIENCE WITH GOES-3 (S-BAND UPLINK) HAS
    REVEALED THE PRESENCE OF UP-LINK MULTIPATH FROM LOCAL SOURCES AT
    POLE AS MEASURED IN THE SIGNAL QUALITY AT MALABAR. MULTIPATH IS ALSO
    AN OBSERVABLE PHENOMENON ON THE POLE RECEIVE SIGNAL AT L-BAND. CLOSE
    IN METALLIC OBJECTS AND BUILDINGS WILL POSE A RECEIVE MULTIPATH
    PROBLEM BY SCATTERING SATELLITE DOWNLINK ENERGY INTO THE ANTENNA.
    CLOSE IN METALIC OBJECTS SHOULD BE AVOIDED.

[^4]: GROUND CLUTTER COULD OBSCURE THE LINE OF SIGHT NEEDED TO THE
    HORIZON. TDRS F1 IS PREDICTED TO RISE TO ONLY 0.86° IN ELEVATION
    DURING THE EARLY MONTHS OF THE TRIALS. GROUND CLUTTER COULD ALSO BE
    A SOURCE OF MULTIPATH. CLOSE IN GROUND CLUTTER IS TO BE AVOIDED.

[^5]: THE SYSTEM MUST CO-EXIST ELECTROMAGNETICALLY WITH ITS
    SURROUNDINGS. IT CANNOT INTERFERE WITH SENSITIVE RECEIVING SYSTEMS
    OR OTHER ELECTRONIC SYSTEMS THAT MAY HAVE IMPLEMENTATION WEAKNESS
    THAT CAUSE STRAY ENERGY PICKUP WHICH ALTERS PERFORMANCE (IE, SENSORS
    WITH LOW LEVEL OUTPUTS). RF RECEIVING SYSTEMS WITH LNA'S IN THE
    VICINITY OF THE EMISSIONS OF THE SPTR SYSTEM MAY BE VULNERABLE TO
    INTERMOD OR GAIN SATURATION INTERERENCE. THE SPTR SYSTEM CANNOT BE
    HARMED BY THE LOCAL ENVIRONMENTAL FIELDS OR RADIO INTERFERENCE. HIGH
    STRENGTH MAGNETIC FIELDS IN THE CLOSE PROXIMITY OF THE TRAVELING
    WAVE TUBES MAY BE A PROBLEM. EM COMPATIBILITY MUST BE ENSURED.

[^6]: SAFETY TO PERSONNEL FROM RADIATION MUST BE ENSURED. EXPOSURE MUST
    FALL WITHIN CURRENT OSHA/IEEE SAFE EXPOSURE LIMITS (EXPOSURE
    DURATION, FREQUENCY DEPENDENT). PLACEMENT OF THE ANTENNAS SUCH THAT
    AREAS FREQUENTED BY STATION PERSONNEL, EXPECIALLY FOR EXTENDED
    DURATIONS, MUST BE AVOIDED WITHIN PRESCRIBED RANGES OF AREAS
    INTERSECTING THE BORESIGHT (MAIN BEAM). GREATEST CONCERN IS FOR
    ACTIVITY CLOSE-IN TO THE ANTENNAS, SINCE SMALL APERTURE SIZE WILL
    HAVE HIGH POWER DENSITYS (W/M^2^ )

[^7]: THE SYSTEM WILL REQUIRE CONNECTION TO THE SOUTH POLE COMPUTER LAN
    BACKBONE. TWO ETHERNET PORTS ARE REQUIRED. TELEPHONE SERVICE (ONE
    LINE) IS NEEDED TO ASSIST IN OPERATIONS AND TROUBLESHOOTING.

[^8]: THE SYSTEM NEEDS 120 VAC AT 35 AMPS (APPROX. 4.2 KVA). TWO 20A
    ELECTRICAL SERVICE CIRCUITS ARE ANTICIPATED.

[^9]: TOTAL ESTIMATED SYSTEM POWER REQUIREMENTS ARE 4.2 KVA (ASSUMED
    PF=1). ADDITIONAL ELECTRICAL POWER MAY BE REQUIRED FOR AUXILLIARY
    HEATING, DEPENDING ON SITE SELECTION. THE BUILDING SERVICE FEEDER
    MUST BE ABLE TO SUPPORT THE ADDED LOAD.

[^10]: THE SITE LOCATION MUST HANDLE THE WASTE HEAT PRODUCED (CIRCULATE
    WITHIN THE FACILITY, ETC.). ADDITIONAL SUPPLEMENTAL HEATING MAY BE
    REQUIRED. THE SYSTEM'S OPERATING THERMAL RANGE IS APPROX. 10°C -
    30°C.

[^11]: THE ANTENNA MOUNT MUST BE FABRICATED IN THE U.S. TO TAKE
    ADVANTAGE OF MATERIALS AND FITTING THE ANTENNAS. THE ANTENNAS MUST
    BE MOUNTED IN A WAY SUCH THAT THEY ARE ACCESSIBLE FOR FOCUS
    ADJUSTMENTS AND AIMING FOR SATELLITE ACQUISITION. ONCE INSTALLED,
    THE ANTENNAS ARE LOCKED DOWN - THE LOCATION MUST BE KEPT UNDISTURBED
    FROM MISALIGNING POINTING. THE ANTENNAS MUST BE REACHABLE WITH POLE
    STATION HEAVY EQUIPMENT (CRANE, ETC.). THE MOUNT MUST MATE WITH THE
    UNDERLYING SUPPORT STRUCTURE AND MUST NOT COMPROMISE THE STRUCTURAL
    INTEGRITY OF THE BUILDING. WIND LOADING MUST BE ACCOUNTED FOR.

[^12]: TWO HOFFMAN BOX ENCLOSURES WILL HOUSE THE CRITICAL ELECTRONICS
    (LNA, DIPLEXER, S-BAND UP/DOWN CONVERTERS) THAT MUST BE WITHIN 10
    FEET OF THE ANTENNA FEED POINTS. DISTANCE RESTRICTION IS REQUIRED TO
    SET SYSTEM SNR AND MINIMIZE UPLINK LOSSES, AS REQUIRED FOR
    PERFORMANCE MARGIN. THESE ENCLOSEURES MUST BE IN MAN-RATED
    (TEMPERATURE) AREAS; THE ELECTRONICS CANNOT BE OBTAINED TO OPERATE
    AT SOUTH POLE WINTER AMBIENTS, GIVEN THE PROJECT'S BUDGET AND TIME
    LINES. THEREFORE, THE ANTENNA WILL NEED TO BE WITHIN 10 FEET OF A
    MAN-RATED AREA. AN ALTERNATIVE IS TO INSTALL INSULATION, A HEATER,
    AND A THERMOSTAT (AC POWERED), BUT THIS REPRESENTS A RELIABILITY
    RISK.

[^13]: SEE PRIOR NOTE.

[^14]: THE S-BAND SYSTEM WILL ROUTE IF SIGNALS (70 MHz) BETWEEN THE
    HOFFMAN BOX ENCLOSURES AND THE EQUIPMENT RACKS THAT ARE IN MAN-RATED
    SPACE. THE MAXIMUM DISTANCE IS EXPECTED TO BE ON THE ORDER OF
    100-200 FEET. THE CABLE WILL PROBABLY BE LOW LOSS PFTE, SOLID
    DIELCTRIC, AND THUS WILL BE FLEXIBLE AND BENDABLE AT ROOM
    TEMPERATURES. THE Ku-BAND SYSTEM WILL REQUIRE THE USE OF ELIPTICAL
    WAVEGUIDE (SEMI-RIDGID) TO MINIMIZE SYSTEM LOSSES, WITH A BEND
    RADIUS OF 1-2 FEET. A MAXIMUM LENGTH OF 50 FEET HAS BEEN SPECIFIED
    BY THE SYSTEM LINK CALCULATIONS TO MAINTAIN SYSTEM FADE MARGINS. AN
    UNOBSTRUCTED PATH WILL BE REQUIRED FOR ROUTING THE WAVEGUIDE, AS THE
    BENDING RADIOUS WILL NOT PERMIT SHARP BENDS AND TURNS.

[^15]: THE SYSTEM WILL REQUIRE TWO 6 FT EIA EQUIPMENT RACKS THAT MUST BE
    IN CLOSE PROXIMITY TO EACH OTHER. EQUIPMENT IN BOTH RACKS MUST
    INTERCONNECT WITH CABLES. THE UNITS CANNOT BE SEPARATED BY ANY
    SUBSTANTIAL DISTANCE. RACK ACCESS SPACE WILL BE REQUIRED IN FRONT
    AND TO THE REAR OF THE RACKS FOR PERSONNEL (TESTING, REPAIR). THE
    RACK LOCATIONS MUST REMAIN FIXED (NOT MOBILE) DUE TO THE Ku-BAND
    ELIPTICAL WAVEGUIDE INTERCONNECTION. TOTAL ESTMATED FLOOR SPACE IS
    70 SQ. FT. (INCLUDED SPACE FOR TEST EQUIPMENT AND A UPS).

[^16]: PRESENT ESTIMATES FOR NASA INSTALLATION REQUIRES 3 PEOPLE FOR 3
    WEEKS FOR THE TOTAL FIELD LIFE CYCLE (ARRIVE, CLIMATIZE, UNPACK,
    SET-UP, DE-BUG, TEST, COMMISSION, USER TRAINING, CLEAN-UP, DEPART).
    THIS IS BASED ON A SIMPLE, STRAIGHT-FORWARD EQUIPMENT INSTALLATION.
    COMPLICATIONS DUE TO ANTENNA MOUNTING (INSTALLATION, ACCESS FOR
    POINTING) AND Ku-BAND WAVEGUIDE INSTALLATION COULD SIGNIFICANTLY ADD
    TO PERSONNEL TIME ON SITE AND ADDS RISK TO THE SUCCESS OF THE
    EFFORT. 3 PEOPLE WITH 3 DISTINCT AND SPECIALIZED SKILLS (SYSTEMS/
    PROJECT, SOFTWARE/NETWORK, RF SYSTEMS) ARE REQUIRED.

[^17]: TOTAL TIME TO INSTALL THE SYSTEM IS CONTINGENT UPON ACCESS TO
    HIGHLY CONSTRAINED SHARED SOUTH POLE STATION INSTITUTIONAL RESOUCES
    FROM THE FACILITIES, MAINTENANCE, AND CONSTRUCTION (FMC) GROUP.
    CARPENTRY, ELECTRICAL WIRING, CRANE OPERATIONS, ETC. WILL BE NEEDED.
    GREATER COMPLEXITY INTRODUCED BY SITE CONFIGURATION/LOCATION COULD
    LIKELY RESULT IN THE CONSUMPTION OF MORE FMC RESOURCES IN TERMS OF
    LABOR HOURS.

[^18]: ASA INFORMATION SYSTEMS WILL BE REQUIRED TO MAINTAIN THE SYSTEM
    DURING THE WINTER PERIOD. ASA HAS ONLY ONE WINTERING COMMUNICATIONS
    TECHNICIAN AND ONE NETWORKING TECHNICAN ALLOTTED FOR THE WINTER
    PERIOD. HIGHLY DISTRIBUTED SITE INSTALLATIONS OR COMPLICATED
    INSTALLATIONS THAT ARE NOT CONDUCIVE FOR EASE OF ACCESS AND
    INTERACTION AMONG ALL THE CONSTITUENT PARTS OF THE SYSTEM BY A
    SINGLE TECHNICIAN WILL SIGNIFICANTLY INCREASE THE LABOR-HOUR DEMANDS
    ON THE SERVICING TECHNICAN, INCREASE THE RISK OF TASK CONFLICTS WITH
    OTHER NEEDED WORK AND RESPONSIBILITIES, AND ADD RISK TO THE SUCCESS
    OF THE PROJECT. PRIOR EXPERIENCE WITH SIMILAR ISSUES WITH THE
    EXISTING GOES-3 EXPERIMENTAL COMM SYSTEM HAVE DEMONSTRATED THAT POOR
    SITE LOCATIONS BY SUSTAINING OPS STANDARDS HAVE A SIGNIFICANT
    IMPACT.
