2) On April 28th 7th IRNSS 1G satellite introduced by Shar
Indian Regional Navigation Satellite System (IRNSS) : NavIC
IRNSS is an independent regional navigation satellite system being 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.

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 travellers
Visual and voice navigation for drivers
The IRNSS Signal-in-Space Interface Control Document (ICD) for Standard Positioning Service (SPS) is released to the public to provide the essential information on the IRNSS signal-in-space, to facilitate research & development and aid the commercial use of the IRNSS signals for navigation-based applications.

This is the last satellite put of 7 and will work till 12 years
It provides navigation facility upto 1500 Km
Helps in knowing status of aeroplane s and ships
Navigation with Indian Consultation is the name given by Prime Minister shri.Narendra Modi

Till now other names are
America GPS
Russia Gonus
Europe Gailelia
China  Beydov
Japan Quasi janith
