he Indian Space Research Organisation (ISRO) is poised to launch its latest marvel, the Earth Observation Satellite EOS-08, using the Small Satellite Launch Vehicle (SSLV)-D3. This mission not only marks the third developmental flight of the SSLV but also showcases ISRO's continuous advancements in satellite technology and launch capabilities.
A New Chapter in Space Exploration
The EOS-08 mission is an ambitious project aimed at designing and developing a microsatellite, creating compatible payload instruments, and integrating new technologies for future operational satellites. Built on the Microsat/IMS-1 bus, EOS-08 is set to carry three significant payloads, each with a unique purpose and advanced capabilities.
Key Payloads on Board
Electro Optical Infrared Payload (EOIR): This payload is engineered to capture images in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands, both during the day and night. Its versatile applications include:
* Satellite-based surveillance
* Disaster monitoring
* Environmental monitoring
* Fire detection
* Volcanic activity observation
* Industrial disaster monitoring
Global Navigation Satellite System-Reflectometry (GNSS-R)
The GNSS-R payload is designed to demonstrate the potential of using GNSS-R-based remote sensing for:
* Ocean surface wind analysis
* Soil moisture assessment
* Cryosphere studies over the Himalayan region
* Flood detection
* Inland waterbody detection
