Focus on commercial use of NaVIC, ISRO’s future satellite to get two additional frequencies

Subject: Science and Development

Recent development in NaVIC-

ISRO is introducing the L1 frequency in all its future satellites.
The next satellites starting from NVS-01 onwards will have L1 frequency.
Aim- To promote civilian use of NAVigation with Indian Constellation (NavIC).
L1 frequency-
- Most commonly used frequency in the Global Positioning System (GPS).
- It will increase the use of the regional navigational system in wearable devices and personal trackers that use low power, single frequency chips.
At present the satellite operates on two freequencies– L5 and S band.
The NVS-01 satellite is set to replace one of ISRO’s seven satellite currently in space.
Two of these satellites- IRNSS-1B and IRNSS-1C– will complete their 10 year mission life in 2024.

Uses of NavIC in India-

It find utilisation in national projects like public vehicle safety
Power grid synchroniztion
Real-time train information system
Fisherman safety
Soon it will come with common alert protocol-based emergency warnings, time dissemination, geodetic network and Unmanned Aerial vehicles.

About NavIC-

NavIC or the Indian Regional Navigation Satellite System (IRNSS) is designed with a constellation of 7 satellites and a network of ground stations operating 24×7.
There are a total of eight satellites however only seven remain active.
Three satellites in geostationary orbit and four satellites in geosynchronous orbit.
The constellations’ first satellite (IRNSS-1A) was launched on 1st July 2013 and the eighth satellite IRNSS-1I was launched in April 2018.
With the seventh launch of the constellation’s satellite (IRNSS-1G), IRNSS was renamed NavIC by India’s Prime Minister in 2016.
It was recognised by the International Maritime Organization (IMO) as a part of the World-Wide Radio Navigation System (WWRNS) for operation in the Indian Ocean Region in 2020.
