Usage of desi navigation system NavIC in national projects increased: Jitendra Singh

Usage of desi navigation system NavIC in national projects increased: Jitendra Singh
NEW DELHI: The Centre has informed that the usage of the Indian Regional Navigation Satellite System (NaviC system) has increased in India. In a written reply to a question in the Lok Sabha, Jitendra Singh said that NavIC finds utilisation in national projects like public vehicle safety, power grid synchronisation, real-time train information system, fishermen safety, etc.

Other upcoming initiatives like common alert protocol-based emergency warning, time dissemination, geodetic network and unmanned aerial vehicles are in the process of adopting the NavIC system, he informed.
Singh said many mobile phone models in the country are already having NavIC compatibility. The Department of Space is constantly engaged with the manufacturers of mobile phones and chipsets to support them technically for adding NavIC compatibility in their devices.
The NavIC system provides signals for positioning. Applications like Google Maps can use the position obtained through NavIC or other similar system and display it on a map or other user interface for easy visualisation. Signals provided by the NavIC system are agnostic to the end-user application. Hence, a mobile phone, which has NavIC compatibility, automatically uses NavIC signals when showing position on maps. Performance of the NavIC system is on a par with other positioning systems.
The current version of NavIC is compatible with L5 and S bands. This is as per the international frequency coordination and compatibility. The current version has been able to penetrate the civilian sector. The addition of signal in the L1 band will help in faster penetration in the civilian sector. The next satellites starting from NVS-01 onwards will have an L1 band for civilian navigational use.
Government is also working to launch replacement satellites NVS-01 onwards for the current seven-satellite constellation. Simultaneously, studies are under way to work out suitable configuration to expand the reach of NavIC beyond its current coverage.
