The Indian Space Research Organisation (ISRO) is currently dealing with a major technical challenge involving its NVS-02 navigation satellite, which was launched on January 29, 2025, using the GSLV-F15 rocket. After the launch, the satellite’s solar panels successfully deployed, and communication with ground control was established. However, a faulty valve has prevented the Liquid Apogee Motor (LAM) from firing, which is crucial for the satellite’s orbit-raising maneuvers. As a result, NVS-02 is stuck in an elliptical Geosynchronous Transfer Orbit (GTO) instead of reaching its intended geostationary orbit.<\/p>\n\n\n\n
What Led to the Orbit-Raising Hurdle?<\/p>\n\n\n\n
The primary issue stems from valves that failed to open, preventing the oxidizer from reaching the thrusters necessary for orbit-raising operations. Despite the satellite\u2019s systems functioning nominally and maintaining communication with ground stations, this malfunction has stalled its progression to the intended orbit.<\/p>\n\n\n\n
How Is ISRO Addressing the Situation?<\/p>\n\n\n\n
ISRO has convened a dedicated committee to explore potential recovery strategies. Efforts to rectify the valve malfunction have been ongoing since the issue was identified post-launch. While the satellite remains operational, the inability to perform orbit-raising maneuvers poses a significant challenge.<\/p>\n\n\n\n
What Are the Implications for India\u2019s Navigation System?<\/p>\n\n\n\n
NVS-02 is part of India\u2019s Navigation with Indian Constellation (NavIC), an independent regional navigation satellite system designed to provide accurate Position, Velocity, and Timing (PVT) services. The current setback with NVS-02 may impact the planned augmentation of the NavIC constellation, which aims to enhance navigation services across India and its surrounding regions.<\/p>\n","protected":false},"excerpt":{"rendered":"
