Indian Space Research Organization (ISRO) on 16 October 2014 successfully launched third navigation satellite Indian Regional Navigation Satellite System (IRNSS) 1C.
Polar Satellite Launch Vehicle (PSLV) C26 injected IRNSS 1C into the designated orbit from the first launch pad of Satish Dhawan Space Centre in Sriharikota. This was the 27th consecutive successful flight of PSLV.
Initially, the satellite was injected into a sub-geosynchronous transfer orbit with a 282.56 km perigee (nearest point to Earth) and 20670 km apogee (farthest point from Earth). Later, it was lifted to a geo-stationary orbit.
IRNSS 1C is the third member of the seven satellite constellation of the IRNSS. The first two satellites in the series were IRNSS 1A and IRNSS 1B.
The fourth navigational satellite of the IRNSS segment will be launched in December 2014 and the project will be fully operational in 2015.
About IRNSS 1C
• The satellite IRNSS 1C is similar in composition to its predecessors 1A and 1B. It carries navigation and ranging payloads.
• It will play a vital role in the IRNSS operations right from guiding drivers on city roads to aerial navigation, disaster management, mapping and surveillance activities.
• IRNSS 1C is designed to provide accurate position information service to users in the country as well as the region extending up to 1500 km from its boundary which is its primary service area.
• The IRNSS 1C will be utilized for two services- Standard Positioning Service (SPS) extended to all users and Restricted Service (RS) which will be encrypted.
• The IRNSS 1C carried two types of payloads, one for transmitting navigation service signals to the users and another consisting of a C-band transponder to facilitate Cube Retro Reflectors for laser ranging.
