ISRO Gears Up for Historic GSLV-F15 Launch with NVS-02 Satellite on January 29
ISRO has officially announced the completion of the GSLV-F15 rocket integration with the NVS-02 satellite, marking a key milestone in India's space program. The launch is scheduled for January 29, 2025, at 6:23 AM IST from the Satish Dhawan Space Centre in Sriharikota. This event is particularly historic, as it will be ISRO's 100th launch from the iconic Sriharikota spaceport.
The GSLV-F15 (Geosynchronous Satellite Launch Vehicle) is equipped with an advanced indigenous cryogenic upper stage, showcasing India's self-reliance in space technology. This launch represents the 17th flight of the GSLV and its 11th flight using the indigenously developed cryogenic stage. It also marks the eighth operational mission of the GSLV with this advanced technology, solidifying the rocket's reliability for complex missions.
At the core of this mission is the NVS-02 satellite, the second installment in the Navigation with Indian Constellation (NavIC) series. NavIC is India's indigenous regional navigation system designed to provide accurate Position, Velocity, and Timing (PVT) services to users in India and its surrounding region, extending approximately 1,500 kilometers beyond its borders.
The NVS-02 satellite has a lift-off mass of 2,250 kilograms and carries advanced navigation payloads operating across the L1, L5, and S frequency bands. It also features a ranging payload in the C-band. One of its most significant features is the use of both indigenous and imported atomic clocks for enhanced precision in timekeeping, which is critical for navigation accuracy.
Once launched, the GSLV-F15 will place the NVS-02 satellite into a Geosynchronous Transfer Orbit (GTO), a preliminary orbit from which the satellite will maneuver into its designated geostationary orbit. This orbit will enable the satellite to provide uninterrupted navigation services within its coverage area, further strengthening India's strategic and civilian navigation infrastructure.
The GSLV-F15 mission underscores India's growing technological maturity in space exploration. The indigenous cryogenic stage, in particular, is a testament to ISRO's efforts to master advanced propulsion technologies, which were once a major challenge due to international restrictions on technology transfer.
The cryogenic engine is capable of operating at extremely low temperatures and offers higher efficiency compared to traditional rocket engines. Its success in previous GSLV missions has paved the way for more ambitious payload launches, including those for interplanetary missions and heavier satellites.
ISRO has extended an invitation to the public to witness the launch event in person from the viewing gallery at Sriharikota. Interested individuals can register online to be part of this momentous occasion. The inclusion of public participation highlights ISRO's commitment to fostering interest and awareness about space science among Indian citizens.
This mission not only demonstrates India’s technological prowess but also strengthens the country’s strategic capabilities in navigation. With the successful launch of NVS-02, NavIC will further enhance its utility in applications such as disaster management, vehicle tracking, and precise time synchronization for infrastructure.
As ISRO continues its journey of groundbreaking achievements, the GSLV-F15 launch is set to add another feather to its cap, symbolizing a significant leap forward for India’s space ambitions.
