Overview
- ISRO, which launched NVS-03 late Friday from the Satish Dhawan Space Centre, placed the roughly 2,232 kg satellite into a geosynchronous transfer orbit and said the injection restored NavIC to its minimum four-satellite operational configuration.
- The spacecraft carries an indigenously developed Rubidium atomic clock alongside procured clocks and will broadcast L1, L5 and S signals to make NavIC interoperable with mainstream consumer devices and improve timing accuracy.
- Controllers will use the satellite’s onboard propulsion over the coming days to raise it from GTO to its assigned geostationary slot at 32.5° East before data relay and full position, navigation and timing services begin.
- ISRO described the GSLV-F18 flight as the 20th GSLV mission and noted a 56-day turnaround since the previous GSLV launch, with about 80 percent of the mission budget spent with Indian industry.
- Restoring NavIC to four satellites reinstates standalone positioning across India and roughly 1,500 km beyond, which affects civilian services such as train, vehicle and maritime tracking and strengthens military resilience and national timekeeping plans.
