ISRO Set To Launch NVS-02 Satellite With Indigenous Atomic Clocks Onboard GSLV-F15 For Enhanced NavIC Services
The Indian Space Research Organisation (ISRO) has rolled out the Geosynchronous Satellite Launch Vehicle (GSLV) to the launchpad with the NVS-02 satellite, which is a part of the Navigation with Indian Constellation (NavIC) system.
Scheduled for 29 January, the GSLV-F15 mission will take off from the Second Launch Pad (SLP) at the Satish Dhawan Space Centre in Andhra Pradesh's Sriharikota.
It will deploy the NVS-02 satellite into a Geosynchronous Transfer Orbit, marking the eighth operational flight of the GSLV equipped with an indigenous Cryogenic stage and the 100th launch from India’s primary spaceport.
NVS-02 is the second satellite in India’s new generation of navigation satellites, part of the Navigation with Indian Constellation (NavIC) system.
NavIC, India’s regional satellite navigation system, delivers precise positioning, velocity, and timing data for users across the country and neighbouring regions, extending up to 1,500 km beyond India’s borders.
The NVS-02 satellite is set to enhance NavIC’s services, which are widely used for applications such as navigation, precision agriculture, emergency services, fleet management, and even mobile device location services.
It has an advanced navigation payload capable of operating on three frequency bands—L1, L5, and S—for high accuracy.
Equipped with the Rubidium Atomic Frequency Standard (RAFS), a precise atomic clock, NVS-02 will ensure accurate timekeeping.
Positioned at 111.75 degree East, the satellite will replace the older IRNSS-1E satellite.
With a weight of 2,250 kg and a power capacity of 3 kW, it incorporates both indigenous and imported atomic clocks.
The inclusion of the new L1 band signals enhances NavIC’s compatibility with global navigation systems, promoting broader adoption and improved service quality.
The NVS-02 satellite has been designed, developed, and integrated at the U R Satellite Centre (URSC).
