ISRO launched the Earth Observation Satellite EOS-08 aboard the SSLV-D3 at 9:17 hrs from Satish Dhawan Space Centre, marking a significant milestone in microsatellite technology. The mission aims to design a microsatellite, develop payloads, and incorporate new technologies for future satellites.
Payloads and Applications
EOS-08 carries three main payloads: the Electro-Optical Infrared Payload (EOIR), Global Navigation Satellite System-Reflectometry (GNSS-R) payload, and SiC UV Dosimeter. These instruments support applications ranging from disaster monitoring and environmental surveillance to cryosphere studies and soil moisture analysis.
Satellite Configuration and Mission Life
Built on the Microsat/IMS-1 bus, EOS-08 operates in a Circular Low Earth Orbit (LEO) at 475 km altitude, with a one-year mission life. The satellite, weighing approximately 175.5 kg, has advanced systems like an Integrated Avionics system and miniaturized phased array antenna for enhanced communication.
Technological Innovations
The EOS-08 mission introduces innovative technologies, including a miniaturized Antenna Pointing Mechanism, flexible solar panels, and thermal management using advanced materials. The mission’s indigenization efforts are evident in its solar cell fabrication processes, demonstrating ISRO’s commitment to advancing satellite technology.
