2. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.
