The Indian Space Research Organisation (Isro) is preparing to launch its latest Earth Observation Satellite, EOS-08, aboard the Small Satellite Launch Vehicle (SSLV)-D3. This mission marks the third development flight of the SSLV.
The mission highlights Isro’s continuous advancements in satellite technology and launch capabilities, focusing on the development of microsatellites and integration of new technologies.
The EOS-08 mission aims to design and develop a microsatellite, create payload instruments compatible with the microsatellite bus, and incorporate new technologies for future operational satellites.
EOS-08 will carry three main payloads: the Electro Optical Infrared Payload (EOIR) for day and night imaging, the Global Navigation Satellite System-Reflectometry payload (GNSS-R) for ocean surface wind analysis and soil moisture assessment, and the SiC UV Dosimeter for monitoring UV irradiance and as a gamma radiation alarm.
The EOIR payload will capture images in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands, with applications in satellite-based surveillance, disaster monitoring, environmental monitoring, and more.
The GNSS-R payload will demonstrate remote sensing capabilities for various environmental analyses, while the SiC UV Dosimeter will be used in the Gaganyaan Mission and for gamma radiation monitoring.
EOS-08 is designed to operate in a Circular Low Earth Orbit (LEO) at an altitude of 475 km and an inclination of 37.4°. It has a mission life of one year and weighs approximately 175.5 kg.
The satellite includes advanced features such as an integrated avionics system, X-band data transmission, and enhanced thermal management materials. It also emphasizes indigenisation efforts, including solar cell fabrication and the use of a Nano-Star Sensor.
The SSLV provides a cost-effective and flexible solution for launching small satellites into low Earth orbit. With a payload capacity of up to 500 kg, it caters to the growing global demand for small satellite launches, making it ideal for Earth observation, communications, and scientific research.
