Recently, ISRO launched the first of seven Indian Navigation Satellites, making India join a handful of nations with their own independent navigation capabilities. By 2016, the remaining 6 will be placed in their orbits, up in the sky which would then offer navigational guidance on Road, in Water and in the Sky.
What are the Applications of Indian Navigation Satellites ?
1) It would help in terrestrial navigation that would aid hikers and travelers.
2) Along with terrestrial navigation it would also boost aerial and marine navigation.
3) Disaster management can be managed with more efficiency.
4) It can be integrated with mobile phones.
5) It will be useful in vehicle tracking and fleet management.
