Focus on commercial use of NavIC, ISRO's future satellites to get additional frequency
- With an aim to promote the civilian use of NAVigation with the Indian Constellation (NavIC), the regional navigation satellite system developed by ISRO is introducing the L1 frequency in all its future satellites.
- The next satellites, starting from NVS-01 onwards, will have an L1 band for civilian navigational use.
L1 frequency
- One of the most commonly used frequencies in the GPS
- Will increase the use of the regional navigation system in wearable devices and personal trackers that use low-power, single-frequency chips.
- Currently, the satellites operate on two frequencies — L5 and S bands.
Navigating the market
- The seven satellites in the NavIC constellation use two frequencies for providing positioning data - L5 and S band.
- The new satellites NVS-01 onwards, meant to replace these satellites, will also have L1 frequency that can be used by devices that run on low power, single-frequency chips such as smart watches and security systems.
Applications of NavIC
- Public vehicle safety
- Power grid synchronisation
- Real-time train information system
- Fishermen safety
- Common alert protocol-based emergency warning
- Time dissemination
- Geodetic network
- Unmanned aerial vehicles
- Mobile phones having chipsets capable of receiving NavIC signals.
