Built on the Microsat/IMS-1 bus, the EOS-08 satellite is equipped with three primary payloads: the Electro-Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry Payload (GNSS-R), and the SiC UV Dosimeter.
The EOIR payload is designed to capture images in both the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands, allowing for day and night operations. Its applications include satellite-based surveillance, disaster monitoring, environmental monitoring, fire detection, volcanic activity observation, and monitoring of industrial and power plant disasters. The GNSS-R payload uses GNSS-R-based remote sensing to analyze ocean surface winds, assess soil moisture, study the cryosphere in the Himalayan region, detect floods, and monitor inland water bodies. The spacecraft will operate in a Circular Low Earth Orbit (LEO) at an altitude of 475 km with a 37.4° inclination and is designed for a mission life of one year.
EOS-08 represents a notable advancement in satellite systems, featuring an Integrated Avionics system called the Communication, Baseband, Storage, and Positioning (CBSP) Package. This system integrates multiple functions into a single, efficient unit with cold redundant systems and uses commercial off-the-shelf (COTS) components. It supports up to 400 GB of data storage and includes key onboard technology components such as a structural panel with embedded PCB, an embedded battery, a Micro-DGA (Dual Gimbal Antenna), an M-PAA (Phased Array Antenna), and a flexible solar panel.
