What is the primary function of the NVS-02 satellite launched aboard GSLV-F15?
- (a)It supports meteorological observations for cyclone prediction.
- (b)It enables satellite-based television broadcasting.
- (c)It boosts India's navigation system by offering precise position and timing data.
- (d)It conducts deep-space communication with planetary probes.
Answer
Why
Correct — C. NVS-02 is a second-generation satellite for NavIC, India's regional navigation system. Its navigation payload works in the L1, L5 and S bands, supplying position and timing signals, alongside a C-band ranging payload.
GSLV-F15 launched it from Sriharikota on 29 January 2025, ISRO's 100th launch from the Satish Dhawan Space Centre.
Why the others are wrong
- (a)It supports meteorological observations for cyclone prediction. — Weather and cyclone watching is the job of meteorological satellites such as the INSAT-3D series, not of a NavIC navigation satellite.
- (b)It enables satellite-based television broadcasting. — Television broadcasting is carried by communication satellites such as the GSAT series. NVS-02 carries navigation and ranging payloads.
- (d)It conducts deep-space communication with planetary probes. — Communication with deep-space probes runs through the ground antennas of the Indian Deep Space Network, not through a navigation satellite.
Concept
NavIC, formerly IRNSS, is India's own satellite navigation system. It covers India and a region of about 1,500 km around it, using satellites in geostationary and inclined geosynchronous orbits.
The NVS series is its second generation. NVS-01 was launched on GSLV-F12 in 2023, and NVS-02 was meant to replace IRNSS-1E.
The mission did not fully succeed. After a good launch, orbit raising could not be carried out because the valves admitting oxidiser to the main engine did not open, so NVS-02 never reached its planned slot. The question asks what it was built to do, which is navigation.
Key facts
- GSLV-F15 launched NVS-02 on 29 January 2025, ISRO's 100th launch from Sriharikota.
- NVS-02's navigation payload operates in the L1, L5 and S bands.
- NavIC serves India and a region of about 1,500 km beyond it.
- NVS-02 could not be raised to its planned orbit because the oxidiser valves for its main engine did not open.

Common traps
- Seeing GSLV and assuming a communication satellite, when the NVS prefix marks the navigation series.
