About NavIC:
- NavIC (NAVigation with Indian Constellation) or the Indian Regional Navigation Satellite System (IRNSS) is an autonomous regional satellite navigation system, that provides accurate real-time positioning and timing services.
Features:
- It consists of three Geostationary Earth Orbit (GEO) satellites and four geosynchronous orbit (GCO) satellites.
- Orbit altitude: 36,000 km
- It will provide two types of services:
- Standard Positioning Services (SPS), which will be provided to all users.
- Restricted Services – (RS), which will grant access only to authorised users (primarily military).
Accuracy:
- IRNSS will have the precision of 10-20 meters for civilian use. It is expected that Military will have more precision.
- GPS has 5 meters coverage for civilian use.
Range:
- It covers India and a region extending 1,500 km around it.
Need for IRNSS:
- During the Kargil war, US government denied vital GPS data for the region to India, necessitating the development of autonomous navigation system for strategic use.
