IRNSS-1C - the 3rd satellite in the Indian Regional Navigation Satellite System (IRNSS) - was launched this morning.

The Indian Space Research Organisation's (ISRO) Polar Satellite Launch Vehicle, PSLV-C26, successfully launched the satellite at 0132 local time (IST) - 2002 UTC on 15 October - from Satish Dhawan Space Centre, Sriharikota.

After a flight of ~20 min 18 sec, the 1,425 kg satellite was injected into an elliptical orbit of ~283 km x 20,670 km. Over the next few days, 4 orbit manoeuvres will be conducted to position the satellite in geostationary orbit (GEO) at 83º E longitude.

Solar panels have been deployed automatically and ISRO's Master Control Facility at Hassan, Karnataka, has assumed control of the satellite.

IRNSS-1C is the 3rd of 7 satellites to constitute the space segment of IRNSS. IRNSS-1A and IRNSS-1B were successfully launched by PSLV on 2 July 2013 and 4 April 2014. Both are reported to be functioning satisfactorily from their designated GEO positions.

The full IRNSS constellation of 7 satellites - 3 GEO and 4 inclined GEO (IGEO) is planned to be operational in 2015. Around 15 ground stations are responsible for the generation and transmission of navigation parameters and satellite control, ranging and monitoring.

IRNSS is planned to furnish position information out to 1,500 km from the Indian mainland, providing 2 types of services - Standard Positioning Services (SPS) for all users and Restricted Services (RS) for authorised users.
