India indegnuously developed IRNSS (Indian Regional Navigation Satellite System) or popularly known as NavIC (Navigation With Indian Constellation) is all set to come on the mobile by the first half of next year. In doing so, Qualcomm inc. an American multinational semiconductor and telecommunications equipment company has done a collaboration with ISRO.
First-ever NavIC demonstration using Qualcomm’s Snapdragon mobile platforms is showcased by the company during the Indian Mobile Congress at New Delhi. According to Qualcomm support for NavIC in Qualcomm chip-set platform will be available from late 2019 and with commercial devices expected to hit market from the first half of 2020.
In a statement, ISRO Chairman Mr. K. Sivan said that,“NavIC is a critical step forward in our pursuit of harnessing space technology for national development and we are eager to make it accessible to everyone for their day to day use. ISRO is very happy to work with Qualcomm to enable NavIC on Mobile platforms. Qualcomm’s technology leadership and support for NavIC on their mobile platforms will bring the benefits of this indigenous solution to every Indian.”
Let’s discuss in detail about NavIC.
NavIC is India own navigation system that provide real-time positioning and timing services. It has a accuracy of 10 m throughout Indian landmass and 0.1 m encrypted accuracy for military use. It has a coverage area of 1600 KM beyond India Borders. An Extended Service Area lies between the primary service area and a rectangle area enclosed by the 30th parallel south to the 50th parallel north and the 30th meridian east to the 130th meridian east.
GPS (Global Positioning System) uses L Band frequency which provide user accuracy of 20-30 m, whereas IRNSS has dual frequency S and L band which makes NavIC more accurate than GPS.
NavIC consists a constellation of 7 satellite with 2 additional satellite on ground. ISRO is planning to expand the satellite number from 7 to 11. Adding 4 additional satellite will help in extending the coverage area.
Some applications of IRNSS are:
- 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 travelers.
- Visual and voice navigation for drivers.
Why India force to develop it’s own satellite navigation system ?
The main motive behind India step to develop it’s Indigenous navigation system is to cut the dependency on GPS, at the time of emergency. Back in year 1999 when Pakistani’s Army illegally annexed the part of Kargil, India government damanded US for help by providing GPS navigation to Indian Army, but US denied.
This forces Indian Government to seek for a indigenously developed navigation system which can help the state in any situation. Government approved the project of IRNSS in May 2013.
