The fifth satellite in the Indian Regional Navigation Satellite System (IRNSS) constellation lifted off on time Jan. 20 from Satish Dhawan Space Center on Sriharikota Island, on India's east coast.
As in the previous four launches of IRNSS satellites, the navigation satellite rode aboard a Polar Satellite Launch Vehicle (PSLV). This is the 33rd launch for the PSLV.
After the PSLV-C31 lift-off at 0401 GMT Wednesday (11:01 p.m. EST Tuesday) with the ignition of the first stage, the subsequent important flight events - strap-on ignitions and separations, first stage separation, second stage ignition, heat-shield separation, second stage separation, third stage ignition and separation, fourth stage ignition and satellite injection - all took place as planned.
We are pleased to announce that the signal quality of the IRNSS Navigation Payload has been tested successfully by using IFEN´s high performance IRNSS Payload Coherence Test Receiver (PCTR).
