Sriharikota: The Indian Space Research Organisation (ISRO) is all set to launch India's fourth navigation satellite—the Indian Regional Navigation Satellite System (IRNSS)-1D on Saturday.
59.5 hours countdown for the launch began on Friday and is progressing smoothly. ISRO will place the 1,425 kg IRNSS-1D satellite in the orbit with its workhorse launching vehicle PSLV C-27. The launch is scheduled at 5.19 pm from the Satish Dhawan Space Centre at Sriharikota.
Earlier, ISRO chairman AS Kiran Kumar was quoted as saying that the launch of the satellite would help a person on the ground locate his geographical position in the Indian region.
"Once four satellites are up in space, using a receiver on ground you can independently locate yourself, you can determine your position in terms of latitude longitude and height. So this will give us independent geographic positioning system in the country," he had said.
The launch was originally scheduled for March 9, 2015, but was later deferred due to an anomaly found in the telemetry transmitter.
According to reports, IRNSS-1D is the fourth in series of seven satellites, planned by ISRO to put in place the Indian Regional Navigation Satellite System. The first three satellites in the IRNSS series were launched from Sriharikota on July 1, 2013, April 4, 2014 and October 16, 2014 respectively.
