NavIC system to be operational again after NVS-03’s successful launch

ISRO's GSLV-F18 rocket successfully launched the NVS-03 satellite, restoring critical positioning and timing services to India's NavIC network. This marks the second GSLV mission for the space agency in two months, showcasing one of the fastest turnaround times for the vehicle. ISRO Chairperson V Narayanan highlighted this achievement as a crucial component of India's 'One Nation, One Time' project.

Prime Minister Narendra Modi praised the ISRO scientists for their success, emphasizing the importance of strengthening the indigenous satellite navigation system. The satellite was precisely placed into a 170.3 x 38,080 km orbit, slightly higher than the intended 170.3 x 37,247 km orbit. Following the launch, the spacecraft will perform a series of maneuvers to transition from its current elliptical orbit to the targeted high, circular orbit.

This launch restores the minimum configuration needed for positioning data, as the NavIC constellation had previously lost this capability due to satellite retirements, atomic clock malfunctions, and launch failures. With three operational satellites currently in orbit - IRNSS-1B, IRNSS-1I, and NVS-01 - the system can provide timing services but not standalone positioning service.

However, when all seven satellites are functioning, NavIC will offer location accuracy up to 10 meters, benefiting various sectors, including construction and the military. Notably, 80% of the launch vehicle budget was contributed by the Indian industry, demonstrating the growing role of private players in the country's space program.
