The Indian Space Research Organization (ISRO) described an issue with its NVS-02 navigation satellite, which was riding on the GSLV-F15 rocket on 29 January. While the satellite successfully reached the classroom and established communication with the ground control, a technical fault stopped the extending exercise. The problem was detected to non-kneading of oxidizer valves, which are important to firing the thrusters required to adjust the position of the satellite. Despite this shock, ISRO confirmed that the satellite systems are functional, and alternative strategies for its operation are being detected.
Navigation satellite in stable class
As InformedAccording to ISRO’s statement, the NVS-02 satellite lives in an elliptical orbit, and its solar panels are required to generate electricity. Communication with the master control facility has been established, ensuring continuous monitoring and control. While the intended class enhancing operations have been stopped, ISRO officials have indicated that the satellite can still be used for navigation in its current class. Discussions are underway to assess the possible adjustment in its mission parameters.
Satellite positioning challenges identified
According to space-tracking data from open-source platforms, NVS-02 satellite has been almost in the same position since its launch, rather than taken to 111.75 degrees east in its specified geostationary slot. The initial launch data indicated that the satellite was placed in an elliptical orbit with a perige of 37,500 km and a perigi of 170 km. While these figures closely match the planned trajectory, the failure of the onboard thrusters to activate has prevented the intended orbital adjustment.
ISRO’s naval expansion plans are ongoing
NVS-02 is the second satellite in the second-generation regional navigation system of India, known as navigation with the Indian Nakshatra. The system is designed to provide exact position, velocity and time (PVT) services throughout India and surrounding areas. The first satellite in the series was launched in 2023, and further deployment is planned to strengthen the Navic network. Despite the current shock, ISRO officials have confirmed that efforts are underway to customize the result of the mission.
