• Abstract:
   One component of the Department of Transportation’s GPS Adjacent Band ; Compatibility Study is the characterization of GPS/GNSS receiver antennas ;  Such characterization is needed to: ;  Compare radiated and conducted (wired) test results ;  Apply interference tolerance masks (ITMs) to use cases where adjacent band transmitters are seen ; by GPS/GNSS receiver antennas at any direction besides zenith (antenna boresight) ;  This presentation summarizes characterization data obtained thus far: ;  Gain patterns for 14 external antennas ; o Right‐hand/left‐hand circular polarization (RHCP/LHCP), vertical (V), and horizontal (H) ; polarizations ; o 22 frequencies: 1475, 1490, 1495, 1505, 1520, 1530, 1535, 1540, 1545, 1550, 1555, 1575, ; 1595, 1615, 1620, 1625, 1630, 1635, 1640, 1645, 1660, and 1675 MHz ;  Approximate L1 RHCP relative gain patterns for 4 antennas integrated with receivers ;  Saturation measurements for the 14 external (all active) antennas ;  All antennas provided by the USG
