GSAT 7 Satellites – UPSC Prelims

GSAT-7 Satellites:
  • GSAT-7 also known as Rukmini is an advanced communication satellite built by ISRO. It was launched in 2013 for the Indian Navy to monitor the Indian Ocean Region and provide real-time data to all the Indian submarines, warships and aircraft.
  • GSAT-7A is an advanced military communications satellite launched by ISRO in 2018. The satellite is currently being used by Indian Air Force (IAF) and Indian Army. The satellite allows IAF to interlink ground-based radars, airborne early warning and control aircraft for surveillance, gather intelligence by detecting aircraft.
  • GSAT-7B:
    • The military-grade satellite will be a force multiplier in providing fail-safe communication support.
    • The GSAT 7B will primarily fulfil the communication needs of the Army.
  • GSAT-7C will be launched in the next 2 to 3 years by ISRO. It will be the 2nd dedicated satellite for the Indian Air Force(IAF).
Software Defined Radios (SDRs):
Software Defined Radio (SDR) provides enhanced data transmission capability, enhanced voice clarity and data transmission accuracy in spectrally noisy environments.
What is the significance of induction of GSAT-7C Satellite and SDRs?
The induction of GSAT-7C Satellite and Software Defined Radios (SDRs) will enhance the ability of Armed Forces to communicate beyond Line of Sight (LoS) among one another in all circumstances in a secure mode.
