The Indian Space Research Organisation (ISRO) will launch Earth Observation Satellite – 06 (EOS-06) and eight nano satellites on November 26.

According to the space agency, the Polar Satellite Launch Vehicle (PSLV-C54) will launch the satellites at 11.56 a.m. from the Satish Dhawan Space Centre in Sriharikota. The EOS-6 is a third-generation satellite in the Oceansat series of satellites.

ISRO is launching this satellite to provide continuity to the services of Oceansat-2 spacecraft with enhanced payload specifications as well as in application areas.

The eight nano satellites include: ISRO Nano Satellite-2 for Bhutan (INS-2B), Anand, Astrocast (four satellites), and two Thybolt satellites. The INS-2B spacecraft will have two payloads namely NanoMx and APRS-Digipeater.

While the NanoMx is a multi-spectral optical imaging payload developed by Space Applications Centre, Ahmedabad, the APRS-Digipeater payload has been jointly developed by the Department of Information Technology and Telecom-Bhutan and the UR Rao Satellite Centre, Bengaluru.

The Anand nano satellite developed by Bengaluru-based space start-up, Pixxel, is a technology demonstrator to demonstrate the capabilities and commercial applications of miniaturised Earth-observation cameras for Earth observation using a microsatellite in Low Earth Orbit.

Astrocast, developed by Hyderabad-based Dhruva Space, is a 3U spacecraft. It is a technology demonstrator satellite for the Internet of Things (IoT).

The U.S.-based Spaceflight has developed Thybolt which is a 0.5U spacecraft bus that includes a communication payload to enable rapid technology demonstration and constellation development for multiple users.

ISRO said that the PSLV-C54 will launch EOS-06 and the eight nano satellites into two different Sun-synchronous polar orbits .

“The primary satellite (EOS-06) will be separated in Orbit-1. Subsequently, a orbit change has been planned by using two orbit change thrusters introduced in the propulsion bay ring of the PSLV-C54. The passenger payloads will be separated in Orbit-2,” ISRO said.
