Correction of the Tracking Data of an Artificial Satellite Considering the Earth Atmosphere and Light Time Effects
We developed a S.W system to simulate the orbit tracking data as nearly equal as the real data obtained at the tracking antenna by modeling various causes that could have effects on the tracking data (range, range rate, azimuth, elevation) of an artificial satellite. Using the S/W developed we produ...
