NEW DELHI: India’s indigenous GPS got a shot in the arm with the launch by the Indian Space Research Organisation (ISRO), of the second generation of navigation satellite NVS-1. More are expected to be launched over the course of the next six months, said Chaitanya Giri, Editor Interstellarnews.in, during a chat on The Gist. Crucial to the success of the satellite are the ISRO-made atomic clocks that will provide precision time by measuring the frequency of atoms, Giri said. These were being imported from Europe and installed on an earlier generation of navigation satellites, but when they broke down, ISRO scientists stepped in to design and make at home. The launch also marks the steady maturation of the cryogenic engines (GSLV series) that use less polluting fuel and are highly efficient. The workhorse PSLV (Polar Satellite Launch Vehicle) need to be upgraded and that work is now getting underway. Tune in for more in this chat with Chaitanya Giri, Editor of Interstellarnews.in.
