Real Time Calibration of Antenna Phase Errors for Ultra Short Baseline Attitude Systems
Real Time Calibration Antenna Phase Errors Ultra Short Baseline Attitude Systems
font style='font-size:12px;'>
2015/6/29
Ultra short baseline attitude systems with base lines under 0.5 meters are desirable for any application which requires a high level of integrity. The higher level of integrity is a direct result of t...
