ISRO's Mission Goals

According to an ISRO statement, the mission's main goals are to design and manufacture a microsatellite, create payload instruments, and integrate new technology.

Launch of Earth Observation Satellite-8 (EOS-8)

Earth Observation Satellite-8 (EOS-8) was launched on Friday by the Indian Space Research Organization (ISRO) from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

Success of SSLV-D3 Developmental Flight

"The third developmental flight of SSLV was successful.EOS-08 was placed exactly into orbit by the SSLV-D3. With this, the SSLV Development Project by ISRO/DOS is successfully concluded. The Indian industry and NSIL India will now develop SSLV for commercial missions thanks to knowledge transfer.

Conclusion of SSLV-D3/EOS-08 Mission

This is the SSLV-D3/EOS-08 mission's third and last developmental flight. The spacecraft is intended to be on a one-year mission.

Objectives of the EOS-08 Mission

According to an earlier ISRO announcement, the main goals of the EOS-08 mission are to design and develop a microsatellite, create payload instruments that are compatible with the microsatellite bus, and incorporate new technologies that will be needed for operational satellites in the future.

Payloads of EOS-08

The Global Navigation Satellite System-Reflectometry Payload (GNSS-R), the SiC UV Dosimeter, and the Electro-Optical Infrared Payload (EOIR) are the three payloads carried by the EOS-08, which is based on the Microsat/IMS-1 bus.

Applications of EOIR Payload

For uses like satellite-based surveillance, disaster monitoring, environmental monitoring, fire detection, volcanic activity observation, and industrial and power plant disaster monitoring, the EOIR payload is made to take pictures in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands both during the day and at night.

GNSS-R Payload Capabilities

The GNSS-R payload showcases the potential applications of GNSS-R-based remote sensing, including analysis of ocean surface winds, evaluation of soil moisture, cryosphere research across the Himalayan region, flood detection, and detection of inland water bodies.

Satellite Configuration and Specifications

With a mission duration of one year, the spacecraft is configured for operation in a Circular Low Earth Orbit (LEO) at an altitude of 475 km and an inclination of 37.4°. The satellite weighs around 175.5 kg and has a power output of about 420 W. It communicates with the launch vehicle SSLV-D3/IBL-358.

Advancements in Satellite Technology

The Communication, Baseband, Storage, and Positioning (CBSP) Package, an Integrated Avionics system that integrates several tasks into a single, effective unit, is one example of the important advancements in satellite mainframe systems that EOS-08 represents. Commercial off-the-shelf (COTS) components and evaluation boards are used in the construction of this cold redundant system, which can accommodate up to 400 GB of data storage.

Onboard Technology Features

The satellite also has an integrated battery, an M-PAA (phased array antenna), a flexible solar panel, a Micro-DGA (dual gimbal antenna), an embedded structural panel, and an embedded PCB, all of which are essential parts of the onboard technology demonstration.
