The New Navigational Satellite of India – After the setback of another

The IRNSS-1I navigation satellite was launched from a Polar Satellite Launch Vehicle (PSLV) by the ISRO (Indian Space Research Organization) from the Satish Dhawan Space Centre located in Sriharikota. It was officially launched on the date of April 12, Thursday, 0404 Indian Standard Time. (6:34 p.m. EDT or 2234 GMT on Wednesday, April 11).

The IRNSS-1I navigational satellite is functioning well in orbit, and once it starts service, the satellite will be a part of the NaVIC (Indian Constellation) system’s Navigation. The NaVIC system provides information regarding the country’s position and also around the mainland surrounding about 932 miles. The IRNSS-1I is said to be NaVIC’s eighth satellite. The IRNSS-1I moved into the first orbit just after 19 minutes of the launch and after which it was moved to its final orbit. The craft is eventually said to orbit the Earth at the same rate as the Earth turns, giving a full-time coverage of a single area of the planet. This is known as geosynchronous orbit.

The Indian Space Research Organization has said that they will perform orbit maneuvers in the coming days in order to position the satellite at a longitude of 55 degrees east in the geosynchronous orbit, with a 29 degrees inclination towards the equator, from the Master/Mission Control Facility (MCF).

This launch of ISRO’s PSLV is the 43rd flight in the rocket line. The PSLV has a successfully launched 52 of Indian satellites and 237 of customer satellites as per the record till now. ISRO was in efforts trying to reestablish contact with an ailing communications satellite of their own, the GSAT-6A. This satellite was launched on top of a GSLV (Geosynchronous Satellite Launch Vehicle) on March 29 and had lost all contact after a few days after the launch. The successful mission of the launch of the IRNSS-1I comes as a comfort for the ISRO after the happenings of GSAT-6A.

ISRO is still trying to reestablish contact with the GSAT-6A satellite, and its location has also been discovered. The attempts to communicate with the satellite is still going on. The GSAT-6A is India’s second troubled mission in 12 months. The country lost the IRNSS 1H satellite (Indian Regional Navigation Satellite System), after the misplacing of the satellite to a lower orbit by the PSLV. There were also media reports which stated that the satellite could not be launched as planned as it was stuck in the rocket’s fairing. However, it has only been India’s first failure of PSLV since the year 1977.
