Motion Controller (Hardware and Software) for LEO Antenna Stations.


The present satellite ground stations for LEO satellites require a motion controller module which tracks the movement of satellites during the visibility. These motion controllers have both software and hardware components. It is proposed to develop an antenna motion controller for LEO satellite antenna stations. The motion controller should be able to steer the antenna up-to velocities of 16 degree/sec or more. The building blocks like axis control cards, safety logic cards, Processor cards, high power relays (3 ph, 440 volts) of this motion controller to be indigenous. The software should be able to accept the ‘.tle’ and related file formats with IRNSS timing signal to steer the antenna for given velocity. Remote operation of the antenna motion controller through an IP network should be possible.
