LOW EARTH ORBIT TRACKING ANTENNA ACCURACY OPTIMATION USING 2-PHASE STEPPER HYBRID MOTOR
08 Dec 2014 • Read : 3681 x ,

To support the utilization of LAPAN satellites in orbit, it’s needed a reliable receiver antenna system at the Ground Station. This antenna system performance is largely determined by the accuracy of its motor beside the RF Front system (LNA, Feed, Cable dan Receiver) used to track the satellite which is moving very fast in low orbit. The movement of satellites in low orbit is about 630 km around 7.5 km/sec. It requires a driving force motor with high accuracy antenna for satellite tracking in light of obtaining the antenna always in the of line of sight to satellite, so that not experiencing any signal losses.
