2020 India has its own GPS system recognised by IMO and is better than GPS in terms of accuracy.
On November 11, India became the fourth country in the world to have its independent regional navigation satellite system recognised by the International Maritime Organisation as a part of the World Wide Radio Navigation System (WWRNS)
Navigation with Indian Constellation (NavIC) will be India's equivalent to USA's GPS
The recognition is only for FOUR countries:
BeiDou of China
GLONASS of Russia
GPS OF USA
And now NavIC of India
It may be recalled, the USA had declined crucial access to GPS to India during Kargil war. GPS support would have proved vital for the Indian forces defending the border of the country against Pakistan. But the US had its own reasons to not extend a helping hand to India.
Some years later in 2009, Sudden Switching off of GPS services by the USA caused failure of BRAHMOS missile test.
The supersonic cruise missile BrahMos missed the target at the Army's range at Pokhran in Rajasthan because its global positioning system (GPS) blanked out The American satellites that run the GPS had been switched off on the day Barack Obama was sworn in as the United States President.
Americans say it was security reasons, but Indians say GPS could have been selectively deactivated.
The missile, therefore, travelled for 112 seconds instead of the slated 84 seconds and fell 7 km away from the target.
India knew it could not depend upon the whims and fancies of the USA
It was then ISRO started building up its own navigation network NavIC
In 2015, ISRO sent 20 satellites in 26 minutes, which carried 13 US satellites. This was the precursor that India was about to reach the next threshold.
Today India has its own GPS version - IRNSS with the operational name NavIC.
Its range is all over India and 1500 km around it. The range is yet to be expanded. But it's more accurate than GPS.
NavIC pushes Atmanirbhar Bharat to the next level.
Congratulations ISRO
