DRDO chief Avinash Chander Showcasing G3OM receiver
The country on Tuesday embarked on a major mission in miniaturising missile systems by successfully testing a G3OM (GPS, GLONASS, GAGAN on a Module) receiver on the BrahMos supersonic cruise missile. Developed by Hyderabad-based Research Centre Imarat, a Defence Research and Development Organisation (DRDO), the G3OM receiver has been produced by a Bangalore-based private firm.
Sources told Express that it is for the first time that a G3OM receiver has been used in any missile worldwide. “It is definitely for the first time an Indian missile is using such a complex system and to our knowledge, no nation has so far tested it. This paves way for highly miniaturised missiles in future. The G3OM weighs around 17 grams and provides hit accuracy below five meters,” an official said. Through G3OM receiver, the missile could take target acquisition from American GPS, Russian GLONASS and India’s GAGAN system at one go.
Combined with inertial navigation system (INS), a G3OM receiver could provide very high accuracies even without a seeker.
