What is IRNSS? 

IRNSS stands for Indian Regional Navigation Satellite System.



The Indian Regional Navigation Satellite System (IRNSS) is an autonomous regional satellite navigation system being developed by the Indian Space Research Organization (ISRO) which would be under complete control of the Indian government

What IRNSS would do? 

It would determine accurately the !NT "ie"  position" navigation and time of an ob#ect



The IRNSS would provide two services" with the Standard !ositioning Service open for civilian use" and the Restricted Service (an encrypted one) for authorized users (including the military)



In other words" the satellites will behave similar to $lobal !ositioning System ($!S) or $%ON&SS

How? 





IRNSS would have seven satellites" out of which four are already  placed in orbit The satellites are named as 

IRNSS Constellation 

IRNSS-1A  is the first navigational satellite in the IRNSS series of satellites been placed in geostationary orbit on  2uly /03 using !S%4'*//



IRNSS-1B  is the second navigational satellite in the IRNSS series of satellites been placed in geostationary orbit on 5 &pril /05 using !S%4'*/5



IRNSS-1C  is the third navigational satellite in the IRNSS series of satellites been placed in geosynchronous orbit on 6 October /05 by using !S%4'*/1
