GSAT-31 India's 40th communications satellite.
A high-throughput Ku-band geostationary spacecraft replacing INSAT-4CR — VSAT, DTH and broadcasting backbone for the Indian subcontinent.

What we flew.
GSAT-31 is India's 40th communications satellite — a 2,536 kg Ku-band bird that took the slot of the ageing INSAT-4CR at 48° E geostationary, providing continuity for VSAT networks, DTH operators, ATM connectivity and broadcasting across the subcontinent.
It launched on 6 February 2019 from Kourou aboard Ariane 5 VA247, alongside Saudi Arabia's HellaSat-4. The spacecraft drifted into its operational slot over the following weeks, with a design life of around 15 years.
Satellize's role was integration support — working alongside ISRO and the platform integrator on RF subsystems and ground-segment readiness. It is the kind of work that does not make headlines, and it is most of what keeps a national satcom network alive.
