- ISRO’s Polar Satellite Launch Vehicle c22
Launch Vehicle, PSLV-C22, has successfully launchedIRNSS-1A, the first satellite in the Indian Regional Navigation Satellite System (IRNSS) from Satish Dhawan Space Centre, Sriharikota. - This is the 23rd consecutively successful mission of PSLV.
- The ‘XL’ configuration of PSLV was used for the mission. Previously, the same configuration of the vehicle was used thrice to launch Chandrayaan-1, GSAT-12 and RISAT-1 satellites.
- After a flight of 20 minutes 17 seconds, the IRNSS-1A Satellite, weighing 1425 kg, was injected to the intended elliptical orbit of 282.46 km X 20,625.37 km.
- After injection, the solar panels of IRNSS-1A were deployed automatically.
- ISRO’s Master Control Facility (at Hassan, Karnataka) assumed the control of the satellite.
- IRNSS-1A is the first of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System.
- 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 only 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.
- As per ISRO the entire IRNSS constellation of seven satellites is planned to completed by 2015-16.
