APPENDIX L 256 frequency increase was predicted. In each scenario, attention was given to the thermal noise limited region and the interference limited region. For military users in a combat environment, receiver and thermal noise is negligible compared with jamming power. Table L-1 Summary of Seven Signal Scenarios with Different Bandwidths, Antennas, and Inertial Aiding Scenario Bandwidth Antenna Used Inertial Code Loop Carrier Loop Aiding Tracking Tracking Bandwidth Bandwidth 1 Y-code Standard No 1.0 Hz (20 MHz) (Baseline) Bandwidth Antenna 20 MHz 2 Y-code Standard Yes 1.0 Hz 1.0 Hz (Baseline) Bandwidth Antenna (aided) (aided) (20 Hz) 3 Y-code Nulling Antenna Yes 0.1 Hz 1.0 Hz (Baseline) Bandwidth (25 dB nulls) (aided) (aided) (20 MHz) 4 Wide Standard No 1.0 Hz 20 Hz Bandwidth Antenna (200 MHz) 5 Wide Standard Yes 1.0 Hz 1.0 Hz Bandwidth Antenna (aided) (aided) (200 MHz) 6 Wide Miniature Yes 0.1 Hz 1.0 Hz Bandwidth Antenna (aided) (aided) (200 MHz) (25 dB nulls) 7 Wide Null/ Yes 0.1 Hz 1.0 Hz Bandwidth Beamforming (aided) (aided) (200 MHz) Antenna (31 dB nulls and 6 dB beam gain) SCENARIO 1: UNAIDED Y-CODE BANDWIDTH SIGNAL WITH A STANDARD ANTENNA For comparison purposes, a baseline of an unaided Y-code bandwidth GPS receiver operating with a standard antenna will be used.
