The servo system of the GMRT, designed in the early 1990s by BARC and subsequently commissioned in the antennas by 1996, is a classical nested loop control system. Some of its major subsystems are undergoing significant upgrades to increase reliability, reduce maintenance and overcome obsolescence of components. These include the solid-state interlock system, a PC104 based servo control computer, and advanced BLDC drives and motors.
