Chennai, Apr 10: The Indian Space Research Organisation (ISRO) will make its second attempt on April 12 to launch a backup satellite to replace NavIC navigation satellite constellation’s IRNSS-1A, which is failing due to technical glitches. The space agency plans to install signal receivers on the ground, which will give weather alerts to fishermen in the sea and will also help them in positioning.

The 1.4tonne IRNSS-1I will be launched from Satish Dhawan Space Centre, Sriharikota. It will replace IRNSS-1A. This would be the second mission to put the replacement satellite into orbit. Last time, the mission had failed after the heat shield failed to separate.

ISRO says the receiver will be connected to fishermen’s phones’ via Bluetooth. The fisherfolks will receive messages on their phones regarding their position in the sea and the weather. Through messages, they will also be apprised about potential fishing zones. All fishermen have to do is to download an application on their phones.

Fishermen are completely cut off from the outside world when they go deep into the sea for fishing. With this, they will get important cyclone alerts, which can save their lives.

ISRO has been on a roll in the last few years. Last month, it successfully launched communication satellite the GSAT6A from Satish Dhawan Space Centre (SDSC) in Sriharikota. The satellite was launched astride GSLV-F08 launch vehicles. The launch was the 12th flight of Geosynchronous Satellite Launch Vehicle GSLV-F08 and sixth flight with an indigenous Cryogenic upper stage. GSAT-6A is similar to GSAT-6, a high power S-band communication satellite built on I-2K satellite bus with a mission life of about ten years.
