@Ohsin Do not see "attitude control thrusters" mentioned. Mentioned is "The satellite was stabilised in GTO using its gyro wheels".
May be they try to raise it´s orbit a bit by a "simple" propellant blow down without burning the prop.

Pyro Valve seems to be the culprit but they still have attitude control thrusters functional.

Not sure what they have in mind but perhaps they want to raise perigee and seek satellite servicing services?
"..Subsequent to the launch, the solar panels .. deployed and power generation is nominal. Com. .. has been established. .. orbit raising.. could not be carried out as the valves for admitting the oxidizer to fire the thrusters ..did not open.
.. mission strategies for utilising the satellite for navigation in an elliptical orbit is being worked out. "

NVS-02 in trouble..

"Subsequent to the launch, the solar panels on board the satellite were successfully deployed and power generation is nominal. Communication with the ground station has been established. But the orbit raising operations towards positioning the satellite to the designated orbital slot could not be carried out as the valves for admitting the oxidizer to fire the thrusters for orbit raising did not open."
