About EOS-08 Earth Observation Satellite
| Aspects | Description |
| About the satellite | The EOS-08 is an Earth Observation Satellite built on ISRO’s Microsat/IMS-1 bus platform. It is designed to operate in a circular Low Earth Orbit (LEO) at an altitude of 475 km and has a mission life of one year. |
| Technological Advancements | 1. The EOS-08 satellite includes an Integrated Avionics System that combines communication, baseband, storage, and positioning (CBSP) functions. 2. It also has a structural panel with an embedded printed circuit board (PCB) and battery. |
| Mission Significance | 1. The successful launch of SSLV-D3 and the precise orbit placement of the EOS-08 satellite are major milestones for ISRO. 2. This mission enhances India’s Earth observation abilities and showcases new advancements in satellite technology. |
About the key payloads
The EOS-08 satellite carries three key payloads:
1. Electro Optical Infrared Payload (EOIR): The EOIR captures images in the Mid-Wave Infrared (MIR) and Long-Wave Infrared (LWIR) bands. It operates day and night, supporting applications like satellite-based surveillance, disaster and environmental monitoring, fire detection, volcanic activity tracking, and industrial disaster monitoring.
2. Global Navigation Satellite System — Reflectometry (GNSS-R) Payload: The GNSS-R payload demonstrates remote sensing using GNSS-R for applications like measuring ocean surface winds, detecting soil moisture, monitoring the Himalayan cryosphere, and identifying floods and inland water bodies.
3. SiC UV Dosimeter: The SiC UV dosimeter measures UV radiation.
