Description

List of integer antenna IDs used in conjunction with the current measurement.

For two-way ground range, and Doppler a single antenna ID identifies the antenna on the satellite. If the list is empty, the default antenna associated with the SatToGround transponder is used. If no such default exists, then the measurement is considered to be to the center of mass.

For two-way space based range, a single antenna ID identifies the antenna on the target satellite. If the list is empty, the default antenna associated with the SatToSat transponder is used. If no such default exists, then the measurement is considered to be to the center of mass.

For one-way bistatic range, BRTS range and BRTS Doppler, the first antenna ID identifies the uplink antenna on the satellite and the second ID identifies the downlink antenna. If the list is empty, the default antennas associated with the Relay transponder are used (default antenna 2 is the downlink). If no such defaults exist, then the measurement is considered to be to the center of mass.

For 4 legged range and 5 legged doppler, the first antenna ID identifies the uplink antenna on the satellite and the second ID identifies the crosslink antenna. If the list is empty, the default antennas associated with the Relay transponder are used (default antenna 2 is the downlink). If no such defaults exist, then the measurement is considered to be to the center of mass.

Note: TDRS antenna ids are returned from the UTDF tracking data provider as 0 - SGL, 1 - SA1, 2 - SA2, 3 - MA.

For GPS CA, P1, and/or P2 pseudorange and/or L1, L2, LA phase a single antenna ID associated with the GPS Receiver is used. If the list is empty, the default antenna associated with the GPS Receiver is used. If no such default exists, then the measurement is considered to be to the center of mass.

For TDOA, FDOA and TDOA Dot the first two antenna IDs identify the uplink and downlink antennas on the path 1 relay satellite and the third and fourth antenna IDs identify the uplink and downlink antennas on the path 2 relay.

For SD TDOA, SD FDOA and SD TDOA Dot the first two antenna IDs identify the uplink and downlink antennas on the path 1 relay satellite and the third and fourth antenna IDs identify the uplink and downlink antennas on the path 2 relay. The fifth and sixth antenna IDs identify the uplink and downlink antennas on the path 3 relay satellite and the seventh and eighth antenna IDs identify the uplink and downlink antennas on the path 4 relay. Note that the path 1 and path 3 use the same relay satellite but can use different uplink and downlink antennas. The same is true for path 2 and path 4.

An ID is added to the AntennaIDs list using the insert method. For example the syntax in perl would be:

$pObs->{AntennaIDs}->Insert(0, $Snum); $pObs->{AntennaIDs}->Insert(1, $Vnum);
