Today (Mar. 28, 2015) ISRO’s Polar Satellite Launch Vehicle, PSLV-C27, successfully launched IRNSS-1D from Satish Dhawan Space Centre, Sriharikota.

The satellite is one among the seven of the IRNSS constellation of satellites slated to be launched to provide navigational services to the region. The satellite is placed in geosynchronous orbit.

The satellite will help augmenting the satellite based navigation system of India which is currently under development. The navigational system so developed will be a regional one targeted towards South Asia. The satellite will provide navigation, tracking and mapping services.

IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS would provide 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 stations responsible for the generation and transmission of navigation parameters, satellite control, satellite ranging and monitoring, etc., have been established in as many as 15 locations across the country.

The first two satellites in the series, IRNSS 1A and IRNSS 1B were launched from Sriharikota on 1 July 2013 and 4 April this year respectively. The IRNSS -1C is the third of seven satellites in a series was launched on Oct 16, 2014.

The IRNSS will provide accurate position information service to users within the country and up to 1,500 km from the nation’s boundary line unlike other navigation system such as GPS by US and GLONASS by Russia. These satellites will be used for used for navigation (marine, aerial and terrestrial) and also for disaster management, vehicle tracking and fleet management, integration with mobile phones, mapping and geodetic data capture among other uses.
