Source- This post on EOS-08 Earth Observation Satellite has been created based on the article “ISRO’s SSLV successfully launches earth observation satellite into orbit” published in “The Hindu” on 17 August 2024.
Why in News?
ISRO has successfully launched the EOS-08 Earth Observation Satellite through the Small Satellite Launch Vehicle (SSLV-D3) from the Satish Dhawan Space Centre (SDSC) in Sriharikota.
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.
