== Launch ==<br />
The GSLV-F15, carrying the [[NVS-02]] satellite, lifted off from the spaceport's second launch pad at 06:23 [[Indian Standard Time|IST]]. The satellite was injected into a [[geostationary transfer orbit]] (GTO) 19 minutes after launch from [[Sriharikota]].<ref>{{Cite web |date=2025-01-29 |title=GSLV-F15 lifts off with NVS-02 satellite in Isro's 100th launch from Sriharikota |url=https://www.indiatoday.in/science/story/isro-gslv-f15-nvs-02-mission-launched-navic-system-100th-lunahc-sriharikota-2671657-2025-01-29 |access-date=2025-02-01 |website=India Today |language=en}}</ref><ref>{{Cite news |last=C.S |first=Hemanth |date=2025-01-29 |title=ISRO successfully launches NVS-02 satellite; creates history with the 100th launch from Sriharikota |url=https://www.thehindu.com/sci-tech/isro-successfully-launches-nvs-02-satellite/article69153254.ece |access-date=2025-02-01 |work=The Hindu |language=en-IN |issn=0971-751X}}</ref><ref>{{Cite news |date=2025-01-29 |title=Isro's GSLV-F15 rocket carrying navigation satellite NVS-02 lifts off from Sriharikota |url=https://timesofindia.indiatimes.com/india/isros-gslv-f15-rocket-carrying-navigation-satellite-nvs-02-lifts-off-from-sriharikota/articleshow/117661968.cms |access-date=2025-02-01 |work=The Times of India |issn=0971-8257}}</ref><br />

==Mission overview ==<br />
Primary payload: [[NVS-02]].<br />
<br />
This launch vehicle is an 3-stage launch vehicle. The first stage of GSLV was also derived from the [[Polar Satellite Launch Vehicle|PSLV]]'s PS1. The 138 tonne solid rocket motor is augmented by 4 liquid strap-ons which is powered by a [[Vikas (rocket engine)|Vikas]] rocket engine. GSLV-F15 payload fairing is a metallic version with a diameter of 3.4 meters.<ref name=":0" /><ref>{{Cite web |date=20 May 2023 |title=Geosynchronous Satellite Launch Vehicle Mark II|url=https://www.isro.gov.in/GSLV_CON.html}}</ref><br />
