• For Civil Aviation: GAGAN:
  1. GPS Aided Geo Augmented Navigation is an augmentation system to engance the accuracy and integrity of GPS signals. It is implemented jointly by AAI and ISRO. It relies on the positioning system of ISRO’s GSAT satellites.
  2. GEMINI system: is a portable receiver linked to ISRO satellites, that is “fail proof” and warn fishermen of danger. GEMINI works on GAGAN (GPS aided Geo Augmented Navigation System).
  3. South Central Railway (HQ – Secundrabad) fitted with Real Time Train Information System (RTIS) to monitor speeds and movement. It is developed by Center for Railway Information Systems (CIRE) with the help of GAGAN of ISRO and AAI.

Indian Regional Navigation Satellite System (IRNSS)

• For positioning, navigation and timing, ISRO is establishing a regional satellite navigation system.
• IRNSS has 3 satellites in geostationary and 4 satellites in geosynchronous orbits (inclined).
• ISRO's NavIC (Navigation in Indian Constellation) is Indian system of 8 Satellites is an indigenous positioning or Location Based System (LBS) which works like GPS but within the 1500 km radius over the subcontinent.

Gagan Enabled Mariner’s Instrument for Navigation and Information (GEMINI) device For effective dissemination of emergency information and communication on Ocean States Forecast and mapping of Potential Fishing Zones (PFZ) to fishermen. Ministry of Earth Sciences. GEMINI is a portable receiver linked to ISRO satellites. It can send signals upto 300 nautical miles. INCOIS, Hyderabad in collaboration with AAI utilized the GAGAN (ISRO + AAI) satellite. The drawback of this device is that it only allows one-way communication, i.e, it can’t be used by fishermen to make calls. Also it is expensive. Bhuvan (Sanskrit for Earth) is a Geoportal of ISRO, allowing a host of services covering visualization, free data download, thematic map display and analysis, timely information on disaster and project-specific GIS applications. Recently an upgraded geo-imaging web portal, Bhuvan Panchayat 3.0 was launched. It uses high resolution data from Earth Observation Satellites and offers detailed information to Panchayats. It is jointly implemented by Ministry of Panchayati Raj and Dept of Space, ISRO.

Why in news?

India’s attempt to place a geoimaging satellite (GISAT-1) with its GSLV-F10-EOS-3 mission did not succeed. The GSLV-F10 rocket, which blasted off from the Satish Dhawan Space Centre at Sriharikota on Thursday, with the purpose of launching the Earth Observation Satellite EOS-3 into space, failed in its mission due to a “performance anomaly”.
