ISRO rocket accomplishes zero orbital debris mission

Through the POEM, which serves as a very cost-effective platform for carrying out short-duration space-borne experiments, ISRO has opened up new vistas for academia, startups, and NGEs to experiment with their new payloads, it said.

This novel opportunity has been effectively utilised by numerous startups, universities, and NGEs for carrying out experiments in space, which included electric thrusters, satellite dispensers, and star-tracking.

POEM also incorporates new features such as total avionics in single-chain configuration, industrial-grade components in avionics packages including Mission Management Computer, standard interfaces for electric power, telemetry & telecommand, and new in-orbit navigation algorithms making use of rate-gyro, sun sensor, and magnetometer, the space agency said.

For the effective conduct of experiments onboard in POEM-3, the body rates were stabilised to less than 0.5 deg/s throughout, and innovative schemes like controlled dumping of residual propellant after the main mission were introduced for minimizing disturbances due to passivation, it added.

Noting that the Vikram Sarabhai Space Centre (VSSC) has taken the lead in conceptualising and realising the POEM by augmenting the 4th stage of PSLV, ISRO said PSLV-C58/XPoSat is the third such mission in the series, with POEMs being successfully scripted each time.

The payload operations were carried out effectively by the spacecraft operations team from the mission operations complex (MOX) at ISRO Telemetry Tracking and Command Network (ISTRAC) and ISRO’s System for Safe and Sustainable Spacecraft Operations Management (IS4OM) has been monitoring and analysing the orbital decay all through, it said. Till near re-entry, POEM-3 was tracked by ISTRAC ground stations.
