Earth Observation Sattellite-8

About Earth Observation Sattellite-8: 

• It will be launched by the Small Satellite Launch Vehicle (SSLV)-D3.
• Objective: The primary objectives of the EOS-08 mission include designing and developing a microsatellite, creating payload instruments compatible with the microsatellite bus, and incorporating new technologies required for future operational satellites.
• It is built on the Microsat/IMS-1 bus and it carries three payloads:
  • Electro Optical Infrared Payload (EOIR): It is designed to capture images in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands, both during the day and night, for applications such as satellite-based surveillance, disaster monitoring, environmental monitoring, fire detection, volcanic activity observation, and industrial and power plant disaster monitoring.
  • Global Navigation Satellite System-Reflectometry payload (GNSS-R): It demonstrates the capability of using GNSS-R-based 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: It 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. The spacecraft has a mission life of one year.

Q1: What is Global Navigation Satellite System-Reflectometry

It is a satellite remote sensing technique that uses surface-reflected GNSS signals to infer information about the Earth’s surface. The reflected GNSS signals act as a bistatic remote sensing radar that responds to changing surface conditions.
