List of Indian satellites

Summary

This list covers most artificial satellites built in and operated by the Republic of India. India has been successfully launching satellites of various types from 1975. Apart from Indian rockets, these satellites have been launched from various vehicles, including American, Russian and European rockets sometimes as well. The organisation responsible for India's space program is Indian Space Research Organisation (ISRO) and it shoulders the bulk of the responsibility of designing, building, launching and operating these satellites.[1]

Legend

This is a list of Indian (wholly or partially owned, wholly or partially designed and/or manufactured) satellites and orbital space crafts, both operated by the Indian government (ISRO, Indian defence forces, other government agencies) or private (educational and research) entities. All satellite launches marked successful have completed at least one full orbital flight (no sub-orbital flights have been included in this list).

Mission status/type legend
  •   Mission failure (due to launch vehicle failure (at launch/during transit))
  •   Extra-terrestrial missions
  •   Geosynchronous Orbit (inclination ≥ 5°)
  •   Geostationary Orbit (inclination < 5°)
  •   Manned spacecraft

1970s

Indian space missions began in the 1970s, with Soviet assistance in launching the first two satellites.

In case of discrepancy in data between sources, N2YO and NASA NSSDCA is taken as the source of truth.
Orbital Longitude is applicable only for Geostationary and Geosynchronous satellites.

1980s

India had three continuous successful satellite launches from its first generation rocket SLV. ISRO had two running projects for next generation rockets based on SLV:

  • ASLV to study and develop technologies to transfer satellites into geostationary orbit.
  • PSLV to transfer higher payloads into polar and sun synchronous orbits.

ISRO did not have enough funds to run both projects simultaneously. Initial setbacks complexity led ISRO to terminate ASLV in just initial flights and focus on PSLV.[8] Technologies to launch geostationary satellites arrived only in 2000s.
