With the advent of smartphones GPS (Global Positioning System) is something that most of the people are aware of. Maps and many more services in your smartphones accurately determine your current position and guide you using the GPS service. But what many people are unaware of is that this GPS service is provided by U.S. That is you are always at a mercy of U.S. to use your smartphone smartly.
With the launch of IRNSS-1E, India is now one step closer to activate its own indigenously Navigation Satellite System that will be used to provide accurate real-time positioning and timing services over India and regions extending to 1500 km around India.
What is IRNSS:
It stands for Indian Regional Navigation Satellite System. It is developed by ISRO with expected cost of expected to be Rs.1420 crore. Fully deployed IRNSS consists of 3 satellites in GEO orbit and 4 satellites in GSO orbit, approximately 36,000 km above the earth surface. The constellation of 7 satellites is expected to operate from 2016 onwards. Out of these 7 satellites, 5 are already launched and next two launches are scheduled in Feb and March 2016. After activating the IRNSS, India will be in the elite group having its own navigation system.
Why India need IRNSS:
The question can be asked why India needs IRNSS when there is GPS service already operational. The reason is that India cannot rely on services controlled by foreign powers as they are not guaranteed in hostile situations. And India had already witnessed such situation in the past during Kargil war, when U.S. denied to provide locations of invading militants to the Indian military. This compelled India to build its own navigation system and ISRO accepted the challenge.
And today India is few months away from using its own positioning system which is something she will be really proud of.
