India's Polar Satellite Launch Vehicle was an Important Move

It was the second successful spacecraft to be launched and marked its 25th consecutive successful mission.
This space craft was required for the Indian Regional Navigation Satellite System (IRNSS) and this will function on a regional scale unlike the GPS.
GPS is based on a constellation of 24 satellites that transmit signals and picks up the signal and work accurately.
Vehicles, aircraft, ships and smart phones depends on GPS signals widely.
GLONASS from Russia, BeiDou from China do operate similarly and Europe and Japan will shortly establish the same to improve coverage.
IRNSS will be serve as important security for military operations.
Other countries may get to access it and there is no surety and guarantee on the same during crisis.
ISRO has gathered 7 satellites to provide accurate navigation signals which can track up to 1,500 km from its borders.
The first satellite is functioning satisfactorily. The second has been put into orbit. 2 more will be launched by this year.
ISRO will take the lead to extend IRNSS services beyond India’s security services.
