Indian Space Research Organisation (ISRO) launched India’s own navigation system IRNSS-1G #Hindustan360

#Hindustan360

SRIHARIKOTA The Indian Space Research Organisation (ISRO) on Thursday developed the India’s own navigation system with the successful launch of IRNSS-1G, the last in the series of seven navigation satellites. Polar Satellite Launch Vehicle (PSLV) C33 carrying IRNSS-1G (Indian Regional Navigation Satellite System) lifted off from the first launch pad at the Satish Dhawan Space Centre in Sriharikota at 12.50. Around 20 minutes after liftoff, PSLV-C33 successfully placed IRNSS-1G in orbit. The satellite has a 12-year mission life. View more at #Hindustan360 .

What does media says
With the completion of the project and setallite launch, India has joined the league of countries that has their own indigenous navigation system. The system will reduce the country’s dependency on US Global Positioning System. Apart from India, only a few other countries, including the US, the European Union, China and Russia have their own navigation systems in place.

For many years now, India has been mostly dependent on the Global Positioning System developed by the US, a project that it began in 1973. However, when the US denied GPS information during the Kargil war in 1999, the nation felt the need for an indigenous navigation system. The IRNSS system is designed to provide accurate position information to users within the country and in the region extending up to 1500km from the boundary.

IRNSS will provide standard positioning service (SPS) for all users with a position accuracy of better than 20 metres and a restricted service (RS) for authorised users with an accuracy of 10 metres. The indigenous navigation system will aid terrestrial, aerial and marine navigation, vehicle tracking and fleet management, disaster management, mapping and geodetic data capture, visual and voice navigation for drivers. The service can also be integrated with mobile phones and can be navigation tool for hikers and travellers.

Advantage of IRNSS-1G:

  • The IRNSS-1E carries two types of payloads – navigation and ranging payload. It weighs 1,425 kg and has an expected life span of over a decade.
  • The first satellite, IRNSS-1A, was launched on July 1, 2013, while the IRNSS-1B was launched in April 2014, the IRNSS-1C in October that year and the IRNSS-1D on March 28 last year.
  • Two more such satellites will be launched in the next two months to fully ready India’s regional navigation system by later this year.
  • The four satellites launched earlier are already operational. While four satellites are sufficient to start operations of the IRNSS system, the remaining three are needed to make the signal available 24×7 with both accuracy and precision, scientists said.
  • The first satellite, IRNSS-1A, was launched on July 1, 2013, while the IRNSS-1B was launched in April 2014, the IRNSS-1C in October that year and the IRNSS-1D on March 28 last year.
