ಸುದ್ದಿಯಲ್ಲಿ ಏಕೆ?
Regional, not global: the NavIC system behind NVS-03 that GS3 Prelims keeps testing
NVS-03 reaches geosynchronous orbit; satellite healthy.
Why it matters: factual, Prelims-type
What you need to know
2 ನಿಮಿಷ
ISRO has said the navigation satellite NVS-03 reached geosynchronous orbit after four orbit-raising manoeuvres, with a cumulative liquid apogee motor burn of 6,164 seconds.
The orbit has an inclination of about 29.98 degrees and the satellite is in good health.
The NVS series strengthens the NavIC regional navigation system.

ಮುಖ್ಯ ಅಂಶಗಳು
Remember these
- NVS-03 reached geosynchronous orbit after four orbit-raising manoeuvres.
- Cumulative liquid apogee motor burn was 6,164 seconds; orbit inclination is about 29.98 degrees.
- ISRO says the satellite is in good health.
- NVS series satellites strengthen NavIC, India's regional navigation system.
- NavIC covers India and an area extending about 1,500 km around it.

How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- NavIC is an independent regional satellite navigation system developed by ISRO, not a global system like GPS or Galileo.
- NavIC covers India and a region extending about 1,500 km beyond its borders.
- GAGAN, a GPS-aided augmentation system, is distinct from NavIC and serves civil aviation.
- A geosynchronous orbit has a period matching Earth's rotation; an inclined one traces a figure-of-eight ground track.
ಮೇನ್ಸ್
GS3 (Science and Technology: space). Indigenous navigation reduces dependence on foreign systems such as GPS for strategic, civil and disaster-management uses. The NVS series renews NavIC's ageing constellation and adds capability; the way forward is wider adoption in smartphones and transport, and sustained launch and satellite-replacement cadence.
