Shriharikota: The Indian Space Research Organisation (ISRO) has successfully launched its latest Earth Observation Satellite, EOS-08, aboard the Small Satellite Launch Vehicle (SSLV)-D3 today at 9:17 AM from the Satish Dhawan Space Centre, marking a significant step forward in India’s space technology and satellite capabilities.
The EOS-08 mission aims to advance satellite technology through the design and development of a microsatellite equipped with cutting-edge payload instruments. Built on the Microsat/IMS-1 bus, EOS-08 carries three key payloads: the Electro Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry payload (GNSS-R), and the SiC UV Dosimeter. These payloads are designed for a range of applications, including satellite-based surveillance, disaster and environmental monitoring, soil moisture assessment, and UV irradiance measurement for the Gaganyaan Mission.
Operating in a Circular Low Earth Orbit (LEO) at an altitude of 475 km, the EOS-08 satellite has a mission life of one year and a mass of approximately 175.5 kg. It is equipped with advanced technologies such as an Integrated Avionics system, miniaturized Antenna Pointing Mechanisms, and flexible solar panels, which enhance its power generation and communication capabilities.
The satellite’s innovative design also features a phased array antenna for improved data transmission, a battery management system with SSTCR-based charging, and advanced thermal management materials. The mission highlights ISRO’s commitment to indigenization and technological advancement, with the incorporation of a Nano-Star Sensor for Microsat Applications and an auto-launch pad initialization feature.
