GSAT-7C (Geosynchronous satellite 7C) is a planned Indian military communication satellite for the Indian Air Force, as part of the GSAT series. On 23 November 2021, the Defence Acquisition Council under the Defence Minister Rajnath Singh approved the Acceptance of Necessity (AoN) of the satellite project. The project is worth ₹2,236 crore (equivalent to ₹25 billion or US$300 million in 2023). The funds were allocated for the development of the satellite and ground hubs for real-time connectivity of software defined radios. Complete design, development, and launching of the satellite will be in India. It will be based on ISRO's I-2000 kg (I-2K) Bus.^[1][2][3]

The satellite will allow beyond the line of sight communications for the Indian Armed Forces to use their BNET SDRs. It's different from other GSAT military satellites because it will be dedicated to secure link software-defined radio communications only. GSAT-7, is a series of satellites developed by Indian Space Research Organisation for the use of Indian Armed Forces. Two satellites in this series are currently functional (7 and 7A) and three more (7R, 7B, and 7C) are planned. The satellite is expected to be launched using a GSLV Mk II rocket.^[4]
