The Space Applications Centre (SAC) develops an indigenous atomic clock for navigation satellites

The Indian Space Research Organisation (ISRO) has developed an indigenous atomic clock that will be used in navigation satellites to measure precise location data. It is being developed by the Ahmedabad-based Space Applications Centre (SAC). 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.
