IRNSS-1B

IRNSS-1B is the second out of seven in the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A.[2] The IRNSS constellation of satellites is slated to be launched to provide navigational services to the region. It was placed in geosynchronous orbit on 4 April 2014.[3][4]

Satellite

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.[5]

IRNSS-1B satellite has two payloads: a navigation payload and CDMA ranging payload in addition with a laser retro-reflector. The payload generates navigation signals at L5 and S-band. The design of the payload makes the IRNSS system interoperable and compatible with Global Positioning System (GPS) and Galileo.[3] The satellite is powered by two solar arrays, which generate power up to 1,660 watts, and has a life-time of ten years.

Launch

The 1,432 kg satellite was launched on 4 April 2014 at 11:44 UTC (17:14 IST) aboard the PSLV-C24 rocket from Satish Dhawan Space Centre, Sriharikota.[4]
