successor to Isro’s earlier GISAT-1 mission<\/a>, which was lost during a launch attempt in 2021.<\/p>\nThe satellite will launch aboard the GSLV-F17 mission from the Second Launch Pad (SLP) at Satish Dhawan Space Centre in Sriharikota.<\/p>\n
WHAT IS INDIA’S GISAT-1?<\/p>\n
GISAT, short for Geo Imaging Satellite, was designed to give India a unique view of the Earth.<\/p>\n
Unlike conventional Earth observation satellites that circle the planet in low-Earth orbit and observe a location only when they pass overhead, a satellite positioned in geostationary orbit can continuously watch the same large region.<\/p>\n
EOS-05 is designed to operate from an orbit about 36,000 kilometres above the equator.<\/p>\n
At this altitude, the satellite orbits Earth at the same rate at which the planet rotates, allowing it to remain in a nearly fixed position relative to the Earth’s surface.<\/p>\n
This capability is expected to allow EOS-05 to repeatedly image the Indian subcontinent and surrounding regions.<\/p>\n
According to the planned mission profile, the satellite will be capable of providing near-real-time imagery at intervals of around 30 minutes. For priority targets, the revisit time could be as short as five minutes.<\/p>\n
Such rapid imaging could prove valuable during fast-changing events.<\/p>\n
WHY ARE EARTH OBSERVATION SATELLITES IMPORTANT FOR INDIA?<\/p>\n
Earth observation satellites are used to monitor clouds and weather systems, assess agricultural conditions, track changes in land and water, and support disaster management.<\/p>\n
Rapid and repeated observations could help agencies monitor developing cyclones, floods, forest fires and other events where conditions can change within minutes.<\/p>\n
The satellite could also support security and strategic observation by providing persistent monitoring of areas of interest.<\/p>\n
Geostationary satellites are commonly used for communication and weather monitoring, but imaging Earth’s surface from such a great distance presents major technological challenges.<\/p>\n
From nearly 36,000 kilometres away, the satellite must collect detailed imagery of a vast region while maintaining precise pointing and stable operations.<\/p>\n
That makes the EOS-05 mission an important technological step for India’s Earth observation programme.<\/p>\n
The September 4 launch will also carry emotional and strategic significance for Isro. The original GISAT-1 mission failed to reach orbit after a problem during the GSLV-F10 launch in August 2021.<\/p>\n
Five years later, the return of the GISAT concept in the form of EOS-05 offers Isro another opportunity to demonstrate continuous Earth imaging from geostationary orbit.<\/p>\n
If successful, EOS-05 could give India a powerful new eye in space, one capable of watching the Indian subcontinent almost continuously.<\/p>\n
