2 ನಿಮಿಷ

ISRO Chairman V.

Narayanan said the NVS-03 navigation satellite is fully healthy and its payload will undergo in-orbit testing.

The satellite supports NavIC, India's regional navigation system and an indigenous alternative to GPS, which uses geostationary and inclined geosynchronous satellites.

How the exam will ask it

ಪ್ರಿಲಿಮ್ಸ್

  • NavIC is a regional navigation satellite system covering India and its surrounding region, not a global system like GPS.
  • The NavIC constellation includes satellites in both geostationary and inclined geosynchronous orbits.
  • NVS-03 is a navigation satellite supporting NavIC, developed and operated by ISRO.

ಮೇನ್ಸ್

GS3 Science & Technology (Space): Dependence on foreign systems like GPS is a strategic vulnerability for navigation, defence and civil services. NavIC, strengthened by the NVS series satellites, offers an indigenous, regionally accurate alternative. The way forward is wider adoption in smartphones and transport, timely launches to keep the constellation healthy, and gradual expansion of coverage.

Answer before you reveal

ಭಾರತದ ಪ್ರಾದೇಶಿಕ ಸಂಚರಣಾ ಉಪಗ್ರಹ ವ್ಯವಸ್ಥೆ ನಾವಿಕ್ (NavIC) ಬಗ್ಗೆ ಈ ಕೆಳಗಿನ ಹೇಳಿಕೆಗಳನ್ನು ಗಮನಿಸಿ:

  1. ಇದು ಜಗತ್ತಿನಾದ್ಯಂತ ವ್ಯಾಪ್ತಿ ಹೊಂದಿರುವ ಜಾಗತಿಕ ಸಂಚರಣಾ ವ್ಯವಸ್ಥೆ.
  2. ಇದರ ಸಮೂಹದಲ್ಲಿ ಭೂಸ್ಥಿರ ಹಾಗೂ ಇಳಿಜಾರಾದ ಭೂಸಮಕಾಲಿಕ ಕಕ್ಷೆಗಳ ಉಪಗ್ರಹಗಳಿವೆ. ಮೇಲಿನ ಯಾವ ಹೇಳಿಕೆ/ಹೇಳಿಕೆಗಳು ಸರಿಯಾಗಿವೆ?
  1. 1 ಮಾತ್ರ
  2. 2 ಮಾತ್ರ
  3. 1 ಮತ್ತು 2 ಎರಡೂ
  4. 1 ಅಥವಾ 2 ಅಲ್ಲ
ಉತ್ತರ ನೋಡಿ

ಉತ್ತರ: B — ಸರಿ: 2 ಮಾತ್ರ — ಹೇಳಿಕೆ 2 ಸರಿ, ನಾವಿಕ್ ಭೂಸ್ಥಿರ ಮತ್ತು ಇಳಿಜಾರಾದ ಭೂಸಮಕಾಲಿಕ ಉಪಗ್ರಹಗಳನ್ನು ಬಳಸುತ್ತದೆ; ಹೇಳಿಕೆ 1 ಅದನ್ನು ತಪ್ಪಾಗಿ ಜಾಗತಿಕ ಎನ್ನುತ್ತದೆ. • 1 ಮಾತ್ರ — ತಪ್ಪು: ಹೇಳಿಕೆ 1 ಸುಳ್ಳು; ನಾವಿಕ್ ಭಾರತ ಮತ್ತು ಸುತ್ತಲಿನ ಪ್ರದೇಶಕ್ಕೆ ಸೀಮಿತವಾದ ಪ್ರಾದೇಶಿಕ ವ್ಯವಸ್ಥೆ. • 1 ಮತ್ತು 2 ಎರಡೂ — ತಪ್ಪು: ಹೇಳಿಕೆ 1 ಸರಿಯಾಗಲು ಸಾಧ್ಯವಿಲ್ಲ; ಜಗತ್ತಿನಾದ್ಯಂತ ವ್ಯಾಪ್ತಿಯ ವ್ಯವಸ್ಥೆ ಜಿಪಿಎಸ್ ಅಥವಾ ಗೆಲಿಲಿಯೋ ಇದ್ದಂತೆ. • 1 ಅಥವಾ 2 ಅಲ್ಲ — ತಪ್ಪು: ಹೇಳಿಕೆ 2 ನಿಖರವಾಗಿದೆ, ಆದ್ದರಿಂದ 'ಯಾವುದೂ ಅಲ್ಲ' ಎಂಬುದು ತಪ್ಪು.
