Why in News?
Indian aims to boost the use of its regional satellite navigation system, NaVIC, on ships and in aircraft that fly far from the nation’s borders.
About NaVIC
- An autonomous regional navigation satellite system called Navigation with Indian Constellation (NavIC) was created to offer location data inside the Indian area and 1500 kilometres of the Indian continent.
- The Indian Space Research Organization (ISRO) intends to replace at least five of them with the upgraded L-Band, allowing it to provide the general public with enhanced global locating services as a number of the constellation’s satellites have reached the end of their useful lifespan.
- Both Standard Positioning Services, which are open to all users, and Restricted Services, which are only available to authorised users, would be offered via IRNSS.

- Terrestrial, Aerial and Marine Navigation
- Disaster Management
- Vehicle tracking and fleet management
- Integration with mobile phones
- Precise Timing
- Mapping and Geodetic data capture
- Terrestrial navigation aid for hikers and travellers
- Visual and voice navigation for drivers
- Seven satellites will make up its constellation because it is a regional system.
- Four of them will be geosynchronous or appear at the same location in the sky at the same time every day.
- Three of them will be geostationary or seem to be stationary in the sky above the Indian Ocean.
- The L-5 Band and S-Band frequencies employed by the present constellation of satellites are used in the transportation and aviation industries.
- With a high likelihood that the majority of them are visible from any location in India, this setup guarantees that each satellite is being tracked by at least one of fourteen ground stations at any one moment.
- Its significance includes:
- National security
- Reliability
- Accuracy
- Disaster management
- South Asian and Regional cooperation
