NVS-02

GSLV-F15 put NVS-02, a second-generation satellite for NavIC, India's regional navigation system, into transfer orbit on ISRO's 100th launch. The satellite was meant to replace IRNSS-1E, one of the system's first-generation satellites.

The valves that admit oxidizer to its orbit-raising thruster did not open, so NVS-02 stayed in an elliptical orbit and never reached its geostationary slot.
