Aiming to measure the precise location data, the Indian Space Research Organization (ISRO), has developed an atomic clock to be used in navigation satellites.
In an interview to news daily, Tapan Misra, director of Ahmedabad-based Space Applications Centre (SAC), said, “SAC has developed an indigenous atomic clock and this clock is currently undergoing a series of qualification tests. Once it successfully clears all tests, the desi atomic clock will be used in an experimental navigation satellite to test its accuracy and durability in space.”
At present, ISRO imports atomic clocks from European aerospace manufacturer Astrium for its navigation satellites. With the development of indigenous atomic clocks, the space agency sure gets a mark of technological advancement. All of the seven navigation satellites of India as part of Indian Regional Navigation Satellite System (IRNSS) or NaVIC have three imported Rubdium atomic clocks each.
The SAC director also addded, “With the development of the desi atomic clock, ISRO has become one of the few space organisations in the world which have gained the capability to develop this highly sophisticated technology. We don’t know the design and technology of the imported atomic clock. But the desi clock has been developed based on our designs and specifications. This clock is as good as the imported one. We are hopeful that it will easily work for more than five years.”
