ISRO today will sign a MoU with the CSIR-National Physical Laboratory for time and frequency traceability services. The move will help the desi GPS to get formally synchronised with the Indian Standard Time. The step will help in making the desi GPS fully operational in the market for commercial purposes as time synchronisation is essential for all kinds of services – be it financial transactions, stock handling, digital archiving, time stamping, national security or prevention of cyber crimes.
The NPL maintains an accuracy of ±20 nanoseconds and thereby gives the most accurate time which is essential for satellite navigation system. It has the “Primary Reference Clock”, which is traceable to the Coordinated Universal Time (UTC) provided by International Bureau of Weights and Measures (BIPM) located in Sevres, France. The UTC consists of a time-scale that combines the output of more than 400 highly precise atomic clocks worldwide, including five at the CSIR-NPL.
The government on Thursday informed the Rajya Sabha about all the measures being taken by ISRO to popularise the desi navigation system at a time when the American GPS dominates the navigation system market across the world.
