CONSTELLATION OF SATELLITES
IRNSS-1G is the last of the seven satellites constituting the space segment of the IRNSS. IRNSS-1A, 1B, 1C, ID, IE and 1F, the first six satellites of the constellation, were successfully launched by PSLV on July 2, 2013, April 4, 2014, October 16, 2014, March 28, 2015, January 20, 2016 and March 10, 2016, respectively. All the six satellites are functioning satisfactorily from their designated orbital positions.
IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1,500 km around the Indian mainland. IRNSS provides two types of services, namely, Standard Positioning Services (SPS) — provided to all users and Restricted Services (RS) — provided to authorised users. A number of ground facilities responsible for satellite ranging and monitoring, generation and transmission of navigation parameters, etc., have been established in 18 locations across the country.
The Minister for the Department of Space, Jitendra Singh, said that the country also plans to launch a communications satellite that will provide enhanced bandwidth connectivity to rural areas. The satellite will be launched towards the end of 2016 or the first quarter of 2017. ISRO plans to launch 22 satellites in another flight of PSLV including 19 satellites from four countries: 13 from the US, three from Germany, two from Canada and one from Indonesia.
