PSLV-C54 successfully places earth observation satellite, 8 nanosatellites in orbit

The eight nanosatellites include ISRO Nano Satellite-2 for Bhutan (INS-2B), Anand, Astrocast (four satellites), and two Thybolt satellites.

In one of its longest missions, the Indian Space Research Organisation (ISRO) successfully placed nine satellites, including an Earth Observation Satellite (EOS-06) in multiple orbits with the help of the space agency’s Polar Satellite Launch Vehicle (PSLV-C54). The vehicle took off precisely at 11.56 a.m. on Saturday from the first launch pad (FLP) at the Satish Dhawan Space Centre (SDSC), SHAR.

The eight nano satellites include ISRO Nano Satellite-2 for Bhutan (INS-2B), Anand, Astrocast (four satellites), and two Thybolt satellites. Notably, EOS-6 is the Oceansat series’ third-generation satellite. This is the 56th flight of the Polar Satellite Launch Vehicle (PSLV) and the 24th flight of the PSLV-XL version with 6 PSOM-Xls.

EOS-06 is envisaged to observe ocean colour data, sea surface temperature and wind vector data to use in oceanography, climatic and meteorological applications. The satellite also supports value added products such as potential fishing zone using chlorophyll, SST and wind speed, and land based geophysical parameters.

The Primary satellite (EOS-06) was separated in Orbit-1. Subsequently, orbit was changed by using two Orbit Change Thrusters (OCTs) introduced in the Propulsion Bay Ring of the PSLV-C54 Vehicle. Later, all the seven commercial satellites from NSIL were deployed successfully. Astrocast, a 3U spacecraft with 4 Satellites from Spaceflight Inc, U.S., were separated.

Following this, the Thybolt, a 0.5U spacecraft bus that includes a communication payload to enable rapid technology demonstration and constellation development for multiple users from Dhruva Space using their own Orbital Deployer with a minimum lifetime of one year, was deployed in the intended orbit. The Anand three axis stabilised nano satellite, a technology demonstrator for miniaturised electro-optical payload and all other sub-systems like TTC, power, onboard computer and ADCS from Pixxel, India was also placed in the orbit.

Further, the India-Bhutan Sat was successfully deployed. A collaborative mission between India and Bhutan, the INS-2B satellite has two payloads namely NanoMx, a multispectral optical imaging payload developed by Space Applications Centre (SAC) and APRS-Digipeater, which is jointly developed by DITT-Bhutan and URSC.

Slew of laucnhes in 2023

Mr. Somanath also said that ISRO will have a slew of launches in 2023. “ISRO is also planning to have its mission to the sun with its satellite Aditya-L1, a coronagraphy spacecraft to study the solar atmosphere, with a PSLV rocket next year,” he said. The space agency will also launch a navigation satellite for the country’s NavIC constellation. “ISRO has planned to launch four NavIC satellites and the first one will go up in 2023.”

Meanwhile, the live launch was witnessed by 10,342 people from the open view gallery at SDSC SHAR, Sriharikota. Thousands of school students from Tamil Nadu, Hyderabad, Bengaluru and from other parts of India gathered at ISRO to watch this rocket take off.
