ISRO (Indian Space and Research Organisation) to halt the launch of GISAT-1 onboard GSLV-F10 due to some technical glitch. The satellite was scheduled to be launch on 5 March 2020.
ISRO informed the country about postpone from their twitter handle.
The launch of GISAT-1 onboard GSLV-F10, planned for March 05, 2020, is postponed due to technical reasons. Revised launch date will be informed in due course.

GISAT-1 (Geo Imaging Satellite-1)
Our country has a number of state-of-the-art earth observation satellites which are dedicated for various thematic applications. But these satellites were generally operate from low Earth orbits due to this they cover a relative smaller region at a time, and have to scan the earth step by step in every revolution around the earth and revisit the same area only after a few days depending on their orbits.
Many applications like meteorology and disaster management require imaging large areas of Earth and atmosphere very frequently. For this the satellite has to be placed in a geostationary orbit which is at an altitude of nearly 36,000 kilometers over the equator.
GISAT-1 is the latest Earth observation satellite developed by ISRO. This will be placed in a geostationary orbit and from its orbital location, GISAT-1 will continuously observe land ocean and atmospheric parameters at relatively higher resolution ranging from 50 to 320 meters using appropriate spectral bands for different applications.
GISAT-1 weighs around 2268 KG and will be launched through GSLV MK II F10 rocket.
GISAT-1 will be India’s first agile Earth observation satellite operating from Geostationary orbit.
After reaching geosynchronous transfer orbit GISAT-1 will be commanded from ground to reach its geostationary orbital slot by using its own propulsion system.
After reaching its geostationary orbit the scan mode of satellite will be activate.
The scan mode includes coverage of entire Indian subcontinent landmass and oceans. It has multi spectral multi resolution imaging instrument which is capable of imaging full or part of the earth disc with high-resolution.
The mission life of the satellite will be around seven years.
GISAT-1 will be utilized for multiple applications which includes crop monitoring, national level draught progression and assessment ocean and coastal zone management, fog detection and warning disaster management dust monitoring and many more Indian Earth observation.
This will be 14th flight of GSLV mark two vehicle and the rocket will take off from the second launch pad of the indian space port at Satish Dhawan Space Centre from Sri Hari Kota.
GSLV MK II comprises three stages.
The first stage consists of a rocket motor with 138 tons of solid propellant and four strap-on boosters each carrying 42 tons of earth storable liquid propellants.
The second stage also uses earth storable liquid propellants while the indigenous cryogenic upper stage forms the third stage the satellite will be placed in the geostationary orbit over the Indian subcontinent.
