ISRO's Telemetry Tracking and Command Network provides TTC (Telemetry, Tracking and Control) support for Launch Vehicles and Spacecrafts for all ISRO missions. BARC (Bhabha atomic research center, Mumbai), ECIL (Electronic Corporation of India limited, Hyderabad) and ISTARC (ISRO Telemetry and Command Network, Bangalore) have developed indigenous ship borne antenna terminal (SBT) to support ISRO missions which also include tracking of reentry vehicles for future Indian manned missions to space. SBT is a multirole three axis TTC terminal which is ship worthy and can be deployed on a ship deck where the ship can be positioned in high seas thus extending TTC support capability even in the remote areas. This 4.6m ship-borne terminal is capable of continuously pointing at the commanded angles and mono-pulse tracking even in the presence of ship's rocking movements. The antenna is actively stabilized against ship movements by the use of an Inertial Measurement Unit (IMU). A stabilization and tracking control system for a ship borne terminal have been developed to drive the antenna in Azimuth, Elevation and Cross Elevation planes. BARC is responsible for the development of three axis gimbals, controller electronics, motor drives, interlocks for the SBT and acceptance testing of the integrated system on Ship deck. This paper describes the realization and validation of stabilization and tracking control system for SBT. |
