NVS-02 spacecraft missed Orbit as drive signal not reachedg pyro valve of oxidizer line of engine for orbit raising : ISRO

Chennai, Feb. 26 -- Citing the on-orbit observations and recommendations of the Apex Committee, the Indian Space Research Organisation (ISRO) has said that drive signal not reaching the pyro valve of the oxidizer line of the enginer meant for orbit raising resulted in NVS-02 satellite missing the intended orbit.
