Abstract:
Our team evaluated the Doppler frequency shift of satellite signals observed by a user on the ground as a function of time. Expressions for determining the radial velocity and position of the satellite using the Doppler frequency shift are derived. Four orbit types are evaluated: LEO, MEO, GEO and Inclined GEO. Modification in our collection cadence and analysis approach for these orbital regimes with rationale is provided. Observed maneuver data collections are highlighted with computed change in velocity and maneuver time. The benefits of such information is discussed, to include an auto track capability for antennas, alternative catalog maintenance sensor, maneuver tip and queue, and anomaly resolution support.
