Isro places earth observation satellite in orbits

SRIHARIKOTA: The Indian Space Research Organisation (Isro) successfully placed earth observation satellite EOS-06 and eight nanosatellites in multi-orbits on Saturday, reports the Times of India.

Isro’s workhorse Polar Satellite Launch Vehicle (PSLV) lifted off from the first launch pad at Sriharikota spaceport at 11.56am in a two-hour multi-orbit launch mission.

The primary payload onboard PSLV-C54 was EOS-06. The 1117kg earth observation satellite was built by UR Rao Satellite Centre, Isro. The nanosatellites included India’s first privately built earth observation satellite Anand. Around 17.17 minutes after lift-off, the rocket’s fourth stage injected EOS-06 (Oceansat-3) into a 742.7km orbit. EOS-06 is a third-generation satellite in the Oceansat series.

This is to provide continuity services of Oceansat-2 spacecraft with enhanced payload specifications as well as application areas. The payloads in the satellite include ocean colour monitor, sea surface temperature monitor, Ku-band scatterometer and Argos.

After placing EOS-06 in orbit, PSLV-C54 travelled around the earth in less than an hour and placed eight nanosatellites in their orbits. The nanosatellites included two Thybolt satellites, communication payloads made by Dhruva Space to enable rapid technology demonstration and constellation development for multiple users.

It was followed by INS-2B satellite (India-Bhutan Sat) which was be injected into a 528.8km altitude. The Isro nanosatellite-2 for Bhutan (INS-2B) has two payloads including NanoMx, a multispectral optical imaging payload developed by Space Applications Centre.

The rocket placed Anand nanosatellite in a low earth orbit. The satellite was built by Bengaluru-based startup Pixxel. It is a technology demonstrator to demonstrate the capabilities and commercial applications of miniaturized earth-observation cameras for earth observation using a microsatellite.

Four nanosatellites from US firm Spaceflight would also be injected into orbit. They were a technology demonstrator for the Internet of Things as the payload.

Saturday’s mission was PSLV’s 56th flight and 24th flight of PSLV-XL version with six XL boosters.
