ESI(Electronics Systems Integration Unit)

The ESI subsystem provides platform interfaces like Gyro and on board Radar Blanking. This unit receives Analog and Digital GYRO inputs from ship and pre- trigger pulses from on board radars of the ship. This unit measures and provides the ship heading data to VARUNA ESM system. It also provides Heading, Roll and Pitch data to the ECM system. This unit also generates band wise composite ESM Rx. Blanking gates and provides all the required interfaces to ESM receiver, ECM System and System Controller units
