Earth Observation Satellite SSLV-D3-EOS8 mission

Current Context : ISRO successfully launched Earth Observation Satellite EOS-08 from Sriharikota.

ABOUT SSLV-D3-EOS8 MISSION

• Objective : designing and developing a microsatellite, creating payload instruments compatible with the microsatellite bus, and incorporating new technologies required for future operational satellites.
• Weighing 5 kg
• Developed by Indian Space Research Organisation (ISRO) with a carrying capacity of 500 kg to the Low Earth Orbit (LEO) .
• Built on the Microsat/IMS-1 bus, the Earth Observation Satellite carries three payloads:

1. Electro Optical Infrared Payload (EOIR)
2. Global Navigation Satellite System-Reflectometry payload (GNSS-R)
3. SiC UV Dosimeter.

• EOIR is designed to capture images in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands
• GNSS-R : Demonstrates remote sensing for applications such as ocean surface wind analysis, soil moisture assessment, cryosphere studies over the Himalayan region, flood detection, and inland waterbody detection.

SiC UV Dosimeter : monitors UV irradiance at the viewport of the Crew Module in the Gaganyaan Mission and serves as a high-dose alarm sensor for gamma radiation.
