New Space Missions

GSAT 7


  • Country's first advanced and full-fledged military communications satellite. 
  • To be used by Indian Navy.
  • Launched from Kourou space port of French Guiana in South America.
  • Rocket: Ariane 5

Utility

  • GSAT-7/ INSAT-4F is expected to significantly improve the country’s maritime security and intelligence gathering in a wide swath on either coasts of the Indian Ocean region. 
  • Built to the Navy’s multiple-band requirements as a platform to safely link up its ships, submarines, aircraft and command from land in real time, it is also the country’s first full-fledged military communication satellite. 
  • Until now the defence forces have used minuscule capacities on ISRO’s various INSAT/GSAT satellites. 
  • UHF (Ultra High Frequency) has never been used until now in an Indian communication satellite; this gives the user (Navy) a long sweep of intelligence network, or what is called COMINT/ELINT (communication intelligence/ electronic intelligence,) on moving non-land platforms like ships. 


        INSAT 3D


  • Launched from Kourou space port of French Guiana in South America.
  • Rocket: Ariane 5
  • INSAT 3D is an advanced meteorological satellite.

Utility

  • INSAT-3D will add a new dimension to weather monitoring through its atmospheric sounding system, which provides vertical profiles of temperature, humidity and integrated ozone from surface to top of the atmosphere. 
  • The six channel imager can take weather pictures of the earth and has improved features compared to the payloads in KALPANA-1 and INSAT-3A, the two Indian Geostationary Satellites providing weather services for the past one decade. 
  • INSAT-3D is equipped with a search and rescue payload that picks up and relays alert signals originating from the distress beacons of maritime, aviation and land based users and relays them to the mission control centre to facilitate speedy search and rescue operations.
  • The major users of Satellite Aided Search and Rescue service in India are the Indian Coast Guard, Airports Authority of India, Directorate General of Shipping, Defence Services and fishermen.
  • The Indian service region includes a large part of the Indian Ocean region covering India, Bangladesh, Bhutan, Maldives, Nepal, Seychelles, Sri Lanka and Tanzania for rendering distress alert services. 


IRNSS IA (Indian Regional Navigation Satellite System)

  • Launched by PSLV.
  • The IRNSS-1A satellite is the first of seven which will make up the Indian Regional Navigation Satellite System (IRNSS). 
  • IRNSS would provide accurate real-time positioning & timing services over India and region extending to 1500 km around India. 
  • It offers two services Standard Positioning Service (SPS) and Restricted Service (RS) with encryption.
  • The constellation will consist of four satellites in geosynchronous orbits inclined at 29 degrees, with three more in geostationary orbit.
