IRNSS – NavIC fully functional confirms DOS
India’s indigenous navigation satellite system termed as Navigation with Indian Constellation (NavIC) is already established by ISRO and is functional since April 2018.NavIC consists of Space Segment (constellation of seven IRNSS satellites) and Ground Segment (spread across India).The system is providing Positioning, Navigation and Timing (PNT) service and one satellite (IRNSS-1A) is providing messaging service.
Use of AIS-140 compliant NavIC-based vehicle trackers system has been made compulsory to all commercial vehicles. More than 75 companies are now manufacturing NavIC based vehicle trackers, and several thousand vehicles are now plying on the roads equipped with these devices. The updated version of new mobile models will be having NavIC based positioning systems. NavIC has been accepted by 3GPP (Third Generation Project Partnership) thereby enabling incorporation of NavIC as part of assisted GNSS. NavIC is also useful for applications like timing solution, drones, surveying, weather radiosondes, forestry, precision agriculture, etc.

IRNSS is an independent regional navigation satellite system developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area.
An Extended Service Area lies between primary service area and area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East.
IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) which is provided to all the users and Restricted Service (RS), which is an encrypted service provided only to the authorised users.
The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area.
IRNSS will be using a combination of GEO and GSO spacecrafts and state-of-the-art ground systems.
IRNSS provides Standard Positioning Service (SPS) and Restricted Service (RS) to the users on dual frequencies in L5 and S band.
NavIC is based on eight satellites. IRNSS- 1 A, 1B, 1C, 1D, 1E, 1F, 1G and 1 I
