The successful launch of the Earth Observation Satellite-8 (EOS-8) by the Indian Space Research Organisation (ISRO) marks another milestone in India’s space journey. Union Home Minister Amit Shah was quick to acknowledge this achievement, extending his congratulations to ISRO through the social media platform X.
Shah highlighted the significance of the launch in enhancing environmental monitoring and disaster management. He also lauded the leadership of Prime Minister Narendra Modi, stating that the successful launch is a testament to India's commitment to humanity under his guidance.
The launch took place at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The mission, known as SSLV-D3, represents the third and final developmental flight of the Small Satellite Launch Vehicle (SSLV).
The satellite was placed precisely into its intended orbit, marking the completion of ISRO's SSLV Development Project. This achievement not only underscores ISRO's growing capabilities but also sets the stage for the Indian industry and NewSpace India Limited (NSIL) to take over the production of SSLVs for future commercial missions, thanks to the transfer of technology.
The primary mission of EOS-8 is to serve as a microsatellite designed for a variety of important tasks. These include environmental monitoring, disaster management, and satellite-based surveillance.
The satellite’s capabilities are enhanced by its three main payloads: the Electro-Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry Payload (GNSS-R), and the SiC UV Dosimeter. Each of these payloads brings unique features that contribute to the satellite's multifaceted role.
The EOIR payload, for example, is capable of capturing images in both the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands, enabling it to function effectively during both day and night.
This capability is particularly valuable for applications such as monitoring natural disasters, observing volcanic activity, and even overseeing industrial sites for potential hazards.
The GNSS-R payload, on the other hand, is focused on remote sensing, particularly for analysing ocean surface winds, assessing soil moisture, and detecting floods and other water-related phenomena.
EOS-8 operates in a circular low-earth orbit (LEO) at an altitude of 475 km, with an inclination of 37.4°. The satellite, which has a mass of approximately 175.5 kg, is designed to operate for one year, generating power of around 420 W.
It features advanced systems, including an integrated avionics package known as the Communication, Baseband, Storage, and Positioning (CBSP) Package. This system integrates multiple functions into a single, efficient unit, showcasing a significant advancement in satellite technology.
In addition to its technological innovations, the satellite also includes components designed for on-board technology demonstrations. These include a structural panel embedded with a PCB, an embedded battery, and advanced antennas like the Micro-DGA and M-PAA.
These components, along with a flexible solar panel, contribute to the satellite's ability to perform its mission efficiently.
