SRIHARIKOTA: India is all set for its major space exploration journey with the 100th launch from the Satish Dhawan Space Centre (SDSC) in Sriharikota. Scheduled for the end of January, the GSLV-F15 mission will deploy the NVS-02 satellite into a Geosynchronous Transfer Orbit (GTO).
This launch, from the Second Launch Pad (SLP), marks the 17th flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV) and the 11th mission featuring the Indigenous Cryogenic Stage. Notably, this will be the 8th operational flight utilizing this indigenous technology, further highlighting India’s advancements in space science and technology.
The GSLV-F15 mission includes a 3.4-meter metallic payload fairing designed to protect the NVS-02 satellite during its launch and ascent. This milestone event reinforces India’s growing capabilities and ambition in the global space sector.
NVS-02: Strengthening India’s Navigation System
At the core of this mission is the NVS-02 satellite, which will be deployed to enhance India’s Navigation with Indian Constellation (NavIC) system. NavIC is India’s regional satellite navigation system that provides accurate Position, Velocity, and Timing (PVT) services. Its coverage extends beyond India, reaching up to 1,500 kilometers outside the country’s borders.
NavIC delivers two services:
Standard Positioning Service (SPS): Provides position accuracy better than 20 meters and timing accuracy better than 40 nanoseconds across its coverage area.
Restricted Service (RS): Reserved for authorized users.
NVS-02, weighing 2,250 kg and powered by a payload capable of handling approximately 3 kW, introduces advanced navigation capabilities across L1, L5, and S bands. It also features a C-band ranging payload, similar to its predecessor, NVS-01, which was launched in May 2023. This satellite will replace IRNSS-1E at the 111.75ºE orbital position, ensuring improved accuracy and reliability of the NavIC system.
Expanding NavIC’s Second-Generation Capabilities
The NVS-02 satellite belongs to the new generation of NavIC satellites, equipped with advanced L1 band signals. These additions aim to extend the scope and performance of NavIC services. The NVS-02, like other satellites in the series, is expected to ensure long-term reliability and sustainability of India’s navigation system.
The satellite was developed at the U R Satellite Centre (URSC) and underwent rigorous testing, including thermal vacuum and dynamic tests, to ensure its readiness. It was transported to the SDSC on January 5, 2025, and is currently undergoing final pre-launch preparations.
With the successful deployment of NVS-02, India’s navigation capabilities will receive a significant boost, strengthening its space infrastructure and showcasing the country’s growing prowess in space technology.
