Desi GPS or NavIC goes v2.0 as the second generation of satellites (NSV) is being placed in orbit. With the latest technology, NavIC is designed to provide user position accurate to better than 20 metres and timing accuracy better than 50 nanoseconds over L1, L5 & S band signals. There will be another 4 NSV satellites for NavIC 2.0 in the coming future. Most important thing about NavIC v2.0 satellites they support the L1 band which makes it truly compatible with most existing navigation systems.
For the first time, an indigenously developed rubidium atomic clock was flown in NVS-01. The space-qualified rubidium atomic clock, indigenously developed by Space Applications Centre, Ahmedabad is an important technology which only a handful of countries possess.
The satellite is powered by two solar arrays, capable of generating power up to 2.4kW and a lithium-ion battery supporting payload and bus load during eclipse. The mission life of NVS-01 is expected to be better than 12 years.
