Context: ISRO successfully launched the GSLV-F15 rocket, placing the NVS-02 satellite into GTO. This milestone marks ISRO’s 100th launch, boosting India’s space prowess.
• The NVS-02 is part of NavIC (Navigation with Indian Constellation), India’s regional navigation satellite system, enhancing positioning accuracy.
About ISRO’s Launch Vehicles:
• What are launch vehicles? Launch vehicles are rocket-powered transport systems designed to carry satellites, spacecraft, or payloads into Earth’s orbit or beyond. They provide the necessary thrust to overcome gravity and place payloads in Low Earth Orbit (LEO), Geostationary Orbit (GEO), or Interplanetary trajectories.

• How do launch vehicles work?
• Rocket Propulsion: Uses Newton’s Third Law to generate thrust via solid or liquid propellants. Multiple Stages: Ascent is divided into stages, where each stage separates after burning its fuel. Guidance & Navigation: Uses precise computing systems to maintain trajectory. Payload Fairing: Protects the satellite and separates when the rocket reaches space. Orbit Insertion: Once in space, the final stage releases the satellite into the desired orbit.

Augmented Satellite Launch Vehicle (ASLV) | 1987 | Five-stage solid-fuelled vehicle, improved SLV’s capacity, retired in the 1990s.
Polar Satellite Launch Vehicle (PSLV) | 1994 | Four-stage vehicle, India’s workhorse rocket, launched Mars Orbiter Mission (Mangalyaan), carries 1,750 kg payload to LEO.
Geosynchronous Satellite Launch Vehicle (GSLV) | 2001 | Three-stage rocket, Indigenous Cryogenic Upper Stage, used for INSAT & GSAT satellites.
GSLV Mk III (LVM3) | 2014 | Heavy-lift vehicle, carried Chandrayaan-2, Chandrayaan-3, can carry 4,000 kg payload to GTO.
Small Satellite Launch Vehicle (SSLV) | 2022 | Low-cost, three-stage solid-fuelled rocket, ideal for launching nano & micro satellites.
• About NVS-02 Satellite: What is NVS-02? NVS-02 is a navigation satellite launched as part of NavIC (Navigation with Indian Constellation). It is the second satellite in the NVS series, replacing aging IRNSS satellites. Orbital Placement: Placed in a Geosynchronous Transfer Orbit (GTO) by GSLV-F15. Final orbit at 36,000 km altitude for regional positioning services. Aim & Purpose To enhance navigation accuracy over India and surrounding regions (1,500 km beyond the Indian mainland). Supports military and civilian applications, including disaster management, fleet tracking, and precision agriculture.
