GISAT 1: New Age Satellite to monitor India continuously to be launched on March 5

The Indian Space Research Organization (ISRO) is to launch GISAT 1 (Geo-Imaging Satellite) in order to watch Indian sub-continent continuously.


The satellite is to be launched by the ISRO on March 5, 2020. The satellite is to be carried by GSLV-F10 rocket. The satellite weighs 2,275 kg and is to be placed in Geosynchronous orbit.


GISAT is Geo-Information Satellite. The satellite is to do a full rotation of the earth and come to the same point every 2 hours. The satellite is capable of performing rapid surveillance and fast imaging. The ISRO has designed the satellite in such a way that if needed the satellite can observe a point for a longer duration.

This is the first satellite to be launched by ISRO in 2020. Following GISAT, 10 more satellites are to be launched to boost space surveillance power of the country. The satellites will also help in strengthening border security and control terrorist infiltration.

IDRSS: ISRO new satellite to help Gaganyaan crew

The Indian Data Relay Satellite System (IDRSS) will track Indian satellites in low-earth orbits. It is a new satellite series that plans to set up a communication system between the space assets of India.


The system is aimed to play vital role in India’s space station and space docking. It will also assist distant expeditions of India to Mars, moon and Venus.

The system will help in monitoring launches. The IRDSS is to play a major role in India’s Human Space Flight Programme, Gaganyaan. It will help India to cover the entire mission right from its launch.

The IDRSS satellites are to be launched on GSLV launcher. They will approximately weigh 2,000 kg. These satellites are to be placed at an orbit of 36,000 km away from earth’s orbit.


The mission consists of more than 2 satellites. The first two IRDSS satellites are to be sent in the end of 2020. These satellites will precede the experimental mission of Gaganyaan that will carry humanoid dummies. The first of this kind is to be launched in 2020 and the second satellite is to be launched in 2021.

This technology was launched by the space majors such as Russia and US in 1970-80s. They were used to monitor their respective space station.


During the launch of Gaganyaan at least one ground should monitor the satellite 24/7. This is not possible for India with its current infrastructure. Also, to make the tracking continuous ISRO has to create number of ground stations or hire them globally. The IDRSS helps to solve this problem providing full time tracking of the mission.
