Secondary timescales traceable to IST have been set up at Regional Reference Standard Laboratories in how many cities?
- A.Three
- B.Five
- C.Seven
- D.Nine
Correct answer
Explanation
The correct answer is five. CSIR-NPL, ISRO and the Legal Metrology Department jointly established secondary timescales at Regional Reference Standard Laboratories in Ahmedabad, Bengaluru, Bhubaneswar, Faridabad and Guwahati. Each of these stays continuously traceable to the IST that CSIR-NPL maintains, which together creates a distributed national architecture for spreading the time. The point of spreading it is resilience: if dissemination depended on a single location, one failure would leave the country without a traceable reference. The five laboratories, along with ISRO's NavIC satellite system and the time dissemination infrastructure of NPL and NIC, add capacity and geographical diversity. Options A, C and D are not supported by the release. A memory aid is that the cities are spread across the west, south, east, north and north-east of the country.
