Indian Space Research Organization (ISRO) has launched its last of the navigational satellite for their series IRNSS on April 28, 2016. IRNSS or Indian Regional Navigational Satellite System is a seven part satellite system that will accurately provide the real-time positioning and timing services over India and a region extending to 1500 km around the country.
The launch took place from Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh. The launch of the navigational satellite system has put India in elite line of countries that have such an indigenous navigational satellite system.

IRNSS – 1G is the seventh satellite following the suite of its predecessors – IRNSS 1A, 1B, 1C, 1D, 1E and 1F. The first satellite was launched in the space on July 1, 2013. Even though the satellite system would have been functional with four satellites but a system of seven satellites would make it even more accurate. How accurate?
It is expected to grant accuracy of better than 66 feet or 20 meters in the primary service area. And this is way more accurate than any other navigational system that the country had offered.
