India moved a step closer to having its own satellite navigation system when scientists of Indian Space Research Organisation (Isro) successfully launched its second Indian Regional Navigation Satellite System(IRNSS-1B) from Sriharikota in Andhra Pradesh on Friday.

With this successful launch, the second of the seven satellite system, India inches closer to a select group of countries that have such a navigation system.
The 1,432 kg satellite was blasted off by the rocket Polar Satellite Launch Vehicle (PSLV C24) at 5.14 pm from the launch pad of Satish Dhawan Space Center. IRNSS-1B is the second navigation satellite of the seven satellites constituting the IRNSS space segment.

Its predecessor IRNSS-1A was launched in July 2013. Two more navigational satellites—IRNSS-1C and IRNSS-1D are scheduled to be launched before the end of 2014.
“The PSLV in its 25th successive successful flight precisely injected India’s seoncd regional navigaton satellite. I thank the entire ISRO team that made the major milestone for the country. This proves again that India’s PSLV has a place of pride.” Isro chairman Dr K Radhakrishnan said.

“This is the second step towards building India’s own navigation system. Satellite navigation is a domain which is constantly evolving. Our Indian Regional Navigation Satellite System will be a regional system, dedicated for usage in Indian main land and 1500km around. By 2015, we should be able to launch all the seven navigational satellites,” Radhakrishnan had earlier told HT.

Soon after the ejection into the orbit the satellite’s solar panels were deployed.

The satellite control was taken over by the Mission Control Facility (MCF) at Hassan in Karnataka.

IRNSS-1B carries two types of payloads — navigation payload and ranging payload. The IRNSS system will provide two types of services — Standard Positioning System provided to all the users and the Restricted Service provided only to authorised users.

Besides applications in surveying, mapping, archaeology, satellite navigation has also proved useful in the fields of maritime, aviation, automobiles, disaster management operations and tracking services.

In June Isro is expected to launch the country’s heavier rocket Geosynchronous Satellite Launch Vehicle – Mark III (GSLV-Mk III).
