The Indian Space Research Organisation (ISRO) plans to launch the Earth Observation Satellite-08 (EOS-08) using the Small Satellite Launch Vehicle (SSLV)-D3 on Independence Day, August 15, at 9:17 a.m.
The launch will occur from the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh. EOS-08 is intended to improve environmental monitoring, and disaster management, and assist with the Gaganyaan mission.
ISRO announces, “It will finalize the SSLV development project and assist with operational missions undertaken by Indian industry and NSIL.”
The satellite consists of three main payloads: the Electro-Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry payload (GNSS-R), and the SiC UV Dosimeter.
Infrared Imaging
The EOIR payload is designed to capture images in both the Mid-Wave Infrared (MIR) and Long-Wave Infrared (LWIR) bands, offering essential data for satellite-based surveillance, disaster monitoring, environmental observation, fire detection, tracking volcanic activity, and assessing industrial disasters.
This payload will function around the clock, ensuring uninterrupted data collection.
The GNSS-R payload showcases the potential of GNSS-R-based remote sensing for diverse applications, such as analyzing ocean surface winds, assessing soil moisture, studying the cryosphere in the Himalayan region, detecting floods, and monitoring inland water bodies. This capability is essential for precise weather forecasting and flood alerts.
The SiC UV Dosimeter measures UV irradiance at the viewport of the Crew Module in the Gaganyaan Mission and acts as a high-dose alarm sensor for gamma radiation, safeguarding the astronauts.
Orbital Specs
Constructed on the Microsat/IMS-1 platform, EOS-08 is designed to function in a Circular Low Earth Orbit (LEO) at an altitude of 475 km with a 37.4° inclination. The satellite has a mass of approximately 175.5 kg, produces around 420 W of power, and is expected to have a mission lifespan of one year.
EOS-08 marks a major advancement in satellite mainframe systems by incorporating an Integrated Avionics system, known as the Communication, Baseband, Storage, and Positioning (CBSP) Package. This system integrates multiple functions into a single, efficient unit, highlighting ISRO’s dedication to innovative mission management.
The launch of EOS-08 on Independence Day not only signifies a technological achievement for ISRO but also highlights India’s advancing capabilities in space exploration and satellite technology.
