The Indian regional navigation satellite system or IRNSS mission of Indian space agency ISRO. It is intended to give exact position data administration to users in India and in addition the locale reaching out up to 1500 km from its limit, which is its essential administration range. An Extended Service Area lies between essential administration range and territory encased 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 -Standard Positioning Service (SPS) which is given to every one of the users and Restricted Service (RS), which is a scrambled administration gave just to the approved users. 

In April 2016,with the last launch of constellation satellite, IRNSS was renamed “NAVIC” by Indian Prime Minister ‘Narendra Modi’. NAVIC – Navigation with Indian Constellation. The total cost of the project is expected to be US$209 million. 

Satellite Constellation

There are 9 satellites in total 
  1. 3 satellite in GEO stationary orbit. 
  2. 4 satellite GEO synchronous orbit. 
    3.
  3. 2 satellite in ground stand by mode.

IRNSS-1A was the first navigational satellite in the Indian regional navigation satellite system series of satellite to be placed in the geosynchronous orbit .The satellite was launched on – board PSLV-C22 on 1 July 2013 from Satish Dhawan Space Centre at Sriharikota.
IRNSS-1B is the second out of seven in Indian regional navigation satellite system. It was very precisely and successfully placed in its orbit through PSLV-C24 rocket on 4 April 2014.
IRNSS-1C is the third out of seven in Indian regional navigation satellite system. The satellite successfully launched using the India’s PSLV-C26 from the Satish Dhawan Space Centre at Sriharikota on 16 October 2014.

IRNSS-1D is the fourth out of seven in Indian regional navigation satellite system. The satellite successfully launched using the India’s PSLV-C27 from the Satish Dhawan Space Centre at Sriharikota on 28 March 2015.

IRNSS-1E is the fifth out of seven in Indian regional navigation satellite system. It was successfully launched on January 20,2016 using India’s PSLV-C31.

IRNSS-1F is the sixth IRNSS satellite. It was launched on 10 March 2016 using India's PSLV-C32.

IRNSS-1G is the seventh IRNSS satellite. It was launched on 28 April 2016 using India's PSLV-C33, which concludes the setting up of the Indian Regional Navigation Satellite System.


PSLV-XL
  1. All the launch vehicles used ‘XL’ version of PSLV
  2. PSLV-XL has also been used for- Mars Orbiter Mision, ASTROSAT, Radar Imaging satellite RISAT-1 and the Communication satellite GSAT-12
Applications 

  1. Earthbound, Aerial and Marine Navigation
  2. Disaster Management 
  3. Reconciliation with mobile phones
  4. Mapping and Geodetic information catch
  5. Earthbound route help for explorers 
  6. Visual and voice route for drivers


Advantages
  1. Accessibility of dependable, scrambled, exact situating and route data from IRNSS-Indian military operations won't need to depend on GPS information 
  2. Amid ordinary circumstances, IRNSS, GPS and GLONASS will be interoperable-regular citizen clients will have extra wellsprings of information, particularly in urban ranges and rugged locales 
  3. This will permit them more noteworthy precision in timing or position estimation. 
  4. More administrations have come to depend on situating and route data. 
  5. This could trigger a blast in GPS applications tuned to NAVIC
