പ്രധാന വസ്തുതകൾ
Remember these
- NVS-03 is an ISRO navigation satellite that reached its intended geosynchronous orbit after four manoeuvres.
- NVS satellites are second-generation satellites meant to strengthen NavIC.
- NavIC stands for Navigation with Indian Constellation; it was earlier called IRNSS.
- NavIC is India's regional navigation system, operated by ISRO.
- NVS-01, the first of the series, was launched in May 2023 on GSLV-F12.

How the exam will ask it
പ്രിലിംസ്
- NavIC is an independent regional satellite navigation system developed by India, unlike GAGAN, which is an augmentation system for GPS signals.
- NVS-series satellites are intended to replace and strengthen the first-generation IRNSS satellites in the NavIC constellation.
- A geosynchronous orbit has a period matching Earth's rotation, at an altitude of about 35,786 km.
മെയിൻസ്
GS3 (Science and Technology: space). Issue: dependence on foreign GNSS such as GPS for civil and strategic needs -> policy: NavIC and its second-generation NVS satellites give India an indigenous regional navigation capability -> implication: better strategic autonomy, and the satellites support transport, disaster management and timing services -> way forward: complete the constellation, push NavIC-enabled chipsets into consumer devices and sustain launch cadence.
PYQ connection
A question UPSC has already asked on this
With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements:
- IRNSS has three satellites in geostationary and four satellites in geosynchronous orbits.
- IRNSS covers entire India and about 5500 sq. km beyond its borders.
- India will have its own satellite navigation system with full global coverage by the middle of 2019.
Which of the statements given above is/are correct?
- 1 only
- 1 and 2 only
- 2 and 3 only
- None
