How the exam will ask it
ప్రిలిమ్స్
- NavIC (Navigation with Indian Constellation) is a regional satellite navigation system developed and operated by ISRO.
- A satellite navigation system needs signals from at least four satellites to compute a position fix in three dimensions plus time.
- NVS-03 is a navigation satellite launched from the Satish Dhawan Space Centre, Sriharikota.
మెయిన్స్
GS3 (Science and Technology: space technology). Regional navigation capability reduces dependence on foreign systems such as GPS for defence, transport, disaster management and timing services; the issue is that ageing satellites eroded NavIC's standalone capability, and the NVS series replaces them. The implication is greater strategic autonomy and civilian use, and the way forward is sustained launches, wider adoption in devices and a robust satellite replenishment schedule.
Quick recall
Answer before you reveal
Following the NVS-03 launch, India's regional navigation system NavIC is back in standalone operation. NavIC is built and operated by which organisation?
- Defence Research and Development Organisation
- Indian Space Research Organisation
- Survey of India
- National Informatics Centre
సమాధానం చూడండి
సమాధానం: B — Correct: Indian Space Research Organisation — ISRO designs, launches and operates the NavIC (Navigation with Indian Constellation) satellites. • Defence Research and Development Organisation — wrong: DRDO builds defence systems and missiles, not the NavIC satellite constellation. • Survey of India — wrong: Survey of India is the national mapping agency and does not operate navigation satellites. • National Informatics Centre — wrong: The National Informatics Centre provides government IT services, not satellite navigation.
