The NVS-02 satellite failed to reach the designated orbit..!
ISRO's NVS-02 satellite, launched as part of its 100th mission, faces technical issues that prevent it from reaching its designated orbit. A malfunction in the oxidizer valves hindered the activation of the satellite's engines. The mission's success is uncertain, and scientists are exploring alternatives to salvage the satellite's functionality. This satellite is critical for India's indigenous navigation system.

New Delhi: ISRO faced unexpected obstacles in its 100th mission launched last Wednesday. The NVS-02 satellite sent into space has encountered a technical fault, ISRO recently announced. "We were unable to place the NVS-02 navigation satellite into the designated orbit. When we attempted to ignite the thrusters in the satellite to increase the orbit, the valves supplying the oxidizers did not open," stated ISRO’s website.
Due to a technical fault in the satellite built at the UR Satellite Centre, the liquid fuel could not be ignited. As a result, scientists believe this mission might be delayed or the satellite might lose its functionality. On January 29, ISRO launched the NVS-02 satellite via the GSLV-F15 rocket from Sriharikota.
It has now been revealed that the failure to send the satellite into the designated orbit was due to issues with the engines on the NVS-02 satellite. The oxidizer needed to be sent into the engines to activate them and bring them into 'on' mode. However, the valves responsible for feeding the oxidizer into the satellite’s engines did not open, preventing the engines from functioning. As of now, the NVS-02 satellite is orbiting in a Geosynchronous Transfer Orbit (GTO). If the satellite continues to orbit in this path, it will not be useful for the operation of the navigation system. ISRO scientists are reportedly working on alternative methods to send the oxidizer into the satellite’s engines. The NVS-02 satellite is very important for India’s indigenous satellite-based navigation system.
