Which satellite navigation system is used to disseminate Indian Standard Time?
- A.GAGAN
- B.NavIC
- C.Galileo
- D.GLONASS
Correct answer
Explanation
The correct answer is NavIC. CSIR-NPL provides traceability of Indian Standard Time to ISRO for the NavIC system, which allows the time to be spread by satellite and strengthens both the availability and the resilience of national timing services. The release lists NavIC alongside network-based routes such as NTP and PTP, and optical fibre technologies such as White Rabbit that are still under testing. Option A, GAGAN, is an Indian satellite-based augmentation system used mainly to improve navigation accuracy for civil aviation, and it is not named here. Options C and D name the European and Russian global navigation satellite systems, which are foreign systems and have no role in disseminating India's legal time. For examinations, link the three routes to their carriers: NTP and PTP over networks, NavIC by satellite, White Rabbit over fibre.
