SRIHARIKOTA: India on Thursday took the final step towards completing its own satellite navigation system, a development heralded by the prime minister as making the nation self-reliant in the field of space-based positioning. The seventh satellite to make up the Indian Regional Navigation Satellite System was launched into space via a rocket from Sriharikota spaceport in southwestern India at 12:50 pm IST (0720 GMT). However, unlike the widely used United States’ Global Positioning System or Russia’s GLONASS, the Indian system will provide positioning information only in India and 1,500 square kilometres (580 square miles) around its periphery. “Until now we were dependent on their systems, now we are self-reliant,” PMModi said in a televised congratulatory message to scientists at the Indian Space Research Organisation.
