ACSS is a high performance Servo System for tracking of Low Earth Orbit Satellites, Geo Synchronous Earth Orbit Satellites, Sun & Stars. ACSS is developed for precise motion control of the parabolic reflector type antennas using the state-of-the-art technology for modern digital control systems. Precise motion control is achieved by backlash removal in large gearboxes used with azimuth & elevation axis of antenna through usage of Dual Drive Counter Torque technique.

Implementation of cascade control for closing the loop using signal being received from satellite with the help of high performance servo-motion controls & high resolution absolute encoders.

ACSS has different operating modes like Standby, Manual, Slew, Designate, Program Track, Step Track, Monopulse Auto Track, Auto Sequence, Computer Designate Mode, Slave & Stow.

We have several installation of ACSS to Space Programs of Satellite Research Organization of India & overseas.
