India to expand NaVIC, make signals more secure: ISRO
India plans to expand its regional satellite navigation system NaVIC in a bid to increase its use in the civilian sector and also by ships and aircraft travelling far from the country's borders.
New Delhi: India plans to expand its regional satellite navigation system NaVIC in a bid to increase its use in the civilian sector and also by ships and aircraft travelling far from the country's borders.
The Navigation with Indian Constellation (NaVIC) uses seven satellites to provide real-time positioning and timing services in India and an area extending up to 1,500 km from the country's borders.
However, several satellites of the constellation have outlived their lives and the Indian Space Research Organisation (ISRO) now plans to replace at least five of these with the improved L-Band, which would enable it to offer better global positioning services to the public.
"We have five more satellites in production, they have to be launched periodically to replace the defunct satellites.
