Isro successfully launches IRNSS-1I navigation satellite

Till now, PSLV has successfully launched 52 Indian satellites and 237 customer satellites from overseas.

Live telecast of the new satellite will be done on Doordarshan, and webcast will be available on ISRO website on Thursday, from 3:30 hours (IST) onwards. ISRO Chairman K Sivan said the mission was a success. Indian Standard Time on Thursday.

According to ISRO, the Indian Regional Navigation Spacecraft System (IRNSS) envisages establishment of a regional navigation system using a combination of GEO and GSO spacecraft. However, the IRNSS-1H satellite launch mission ended in a failure on August 31 previous year. We are going to have GSAT, PSLV missions.

Satellite IRNSS-1H, which was earlier meant to replace IRNSS-1A, failed to deploy on 31 August 2017 as the heat shields failed to separate from the 4th stage of the rocket.

There were plans for the 5.7-tonne GSAT-11 mission, a throughput satellite using Arianne rocket, he said, adding that it would be the heaviest satellite the space agency has made so far.

"Engineers were working 24X7 and had been able to locate the satellite". "IRNSS-1A will continue to remain in orbit for messaging purposes", the ISRO spokesperson confirmed to ThePrint.

The 1,425-kg satellite - part of the Indian Regional Navigation Satellite System (IRNSS) - will be carried by Polar Satellite Launch Vehicle (PSLV) rocket XL variant that will blast off on at around 4.04 AM., the official said.

The ranging payload of IRNSS-1I consists of a C-band transponder, which facilitates accurate determination of range of satellite. "The baby has been delivered, and it's unfolded its solar arrays". The IRNSS-1L is ninth in the NavIC satellite constellation that will replace the faulty IRNSS-1A satellite after it developed faults in three cesium clocks from the last two years.

Like its other IRNSS predecessors, IRNSS-1I also carries two types of payloads for navigation and ranging.

The NavIC constellation has three satellites in circular geostationary orbits over the equator, and four craft in inclined orbits - like IRNSS 1I - that oscillate north and south of the equator, ensuring multiple satellites are always high in the sky over the Indian subcontinent. NavIC, also known as Indian Regional Navigation Satellite System (IRNSS), is an independent regional navigation satellite system created to provide position information in the Indian region and 1,500 km around the Indian mainland. The program provides enhanced navigation coverage when combined with signals from GPS satellites, and independent positioning data in case foreign navigation signals are cut off.
