A damaged electrical circuit is most probably why the Indian House Analysis Organisation (ISRO) didn’t put navigation satellite tv for pc NVS-02 in its supposed orbit in January final 12 months, in line with a committee assessing the mission’s failure.
The NVS-02 satellite tv for pc was injected in an elliptical switch orbit utilizing the GSLV-F15 by the area company in its a centesimal launch on January 29 final 12 months. Nonetheless, subsequent manoeuvres to put the satellite tv for pc in its supposed round orbit failed, that means it couldn’t be used for its supposed objective of satellite-based positioning.
Whereas a collection of autonomous actions comparable to deployment of photo voltaic panels and fixing the orientation for energy technology have been carried out as deliberate afterwards, the engine meant to place the satellite tv for pc within the last orbit failed.
‘Sign didn’t attain pyro valve’ important purpose: ISRO
After thorough evaluation of simulation information, the apex committee constituted to assessment the case concluded that the principle purpose for the failure was a sign not reaching the pyro valve of the oxidiser line of the engine. Because of this the engine couldn’t be ignited. This, the committee felt, was most probably due to the disengagement of a minimum of one of many contacts to the connector — that means the circuit to ship the sign couldn’t be accomplished.
“The committee has offered a set of suggestions geared toward enhancing the redundancy and reliability of pyro system operations for future missions,” the area company stated in a press release.
These suggestions have been adopted for the CMS-03 satellite tv for pc launched in November final 12 months, during which all of the pyro programs carried out as anticipated and positioned the satellite tv for pc within the supposed orbit.
In the meantime, the area company has additionally constituted a committee to assessment the rationale for anomalies within the PSLV rocket following a failed launch in January this 12 months.

The ISRO’s workhorse failed twice, again to again in Might final 12 months and January this 12 months, with the satellites in each instances failing to succeed in their supposed orbit after an anomaly within the third stage of the rocket.
Whereas the committee is but to research the 2 occasions, Union minister of state for area Dr Jitendra Singh stated that each the failures have been resulting from unrelated causes.
