What is GPS ? Explain the recent efforts made by India to create its own GPS system.
In short
GPS is a satellite navigation system giving real-time location and timing worldwide, and denial of access during the Kargil War pushed India to build its own. Its answer is NavIC (IRNSS), seven ISRO satellites with 15 ground stations, giving better than 20 metre accuracy over India and 1,500 km beyond.
