PSLV (C-31) launches the 5th satellite of IRNSS

Sriharikota, Jan 20: In a breakthrough in the field of space science, ISRO has launched the PSLV-C31, which carries the IRNSS-1E, from Sriharikota.

In fact, this is ISRO's 50th orbital launch with the PSLV deploying the IRNSS navigation satellite into geosynchronous transfer orbit.

The IRNSS is designed to use seven satellites in geosynchronous orbits, enabling India to have a satellite navigation system that is not reliant on other countries' space technology.

The navigation system will also be useful in disaster management, vehicle tracking and fleet management, integration with mobile phones, mapping and geodetic data capture, visual and voice navigation for drivers and others.

This adds on to four regional navigational satellites (IRNSS-1A, 1B, 1C and ID), which form a part of the constellation of 7 satellites to enable providing accurate position information service to users across the country.

The constellation will be fully fucntional after the launches of IRNSS-1F and 1G, which have been scheduled to be launched for February and March. However, ISRO recently announced plans for four additional reserve spacecraft.
