EOS-09, also known as RISAT-1B, is a cutting-edge radar imaging satellite developed by ISRO. Its primary objective is to enhance India’s border and coastal surveillance capabilities. This satellite captures high-resolution images of the Earth's surface under all weather conditions, ensuring effective monitoring both day and night.
The launch of EOS-09 is scheduled for May 18, utilizing the PSLV-C61 mission. The launch will take place from the Satish Dhawan Space Centre located in Sriharikota.
The C-band SAR technology is crucial for the functionality of EOS-09. It enables the satellite to capture clear images even through clouds, fog, and darkness. This capability is essential for detecting intrusions and tracking enemy movements, which is vital for anti-terrorist operations. For instance, EOS-09 can monitor infiltration attempts along the Line of Control (LoC) with Pakistan during heavy monsoons or at night.
Unlike regular optical satellites, which cannot operate effectively in cloudy conditions or at night, EOS-09 utilizes radar technology to provide continuous surveillance. This reliability ensures that even when optical satellites may overlook activities due to adverse weather, EOS-09 can capture radar images and alert security forces promptly.
EOS-09 will significantly benefit regions along India’s borders with Pakistan and China, as well as the vast Indian coastline. For example, it can effectively monitor unusual boat movements along the Gujarat coast or troop movements in Ladakh, thereby enhancing national security.
In addition to military uses, EOS-09 has a wide range of applications in non-military fields. It can aid in agriculture, forestry, monitoring water bodies, soil moisture studies, geology, and disaster management. For instance, it can assist in assessing crop health or tracking flooded areas during cyclones.
EOS-09 is part of a larger series of satellites and serves as a follow-on to RISAT-1. It works in conjunction with other important satellites such as RISAT-2B, Cartosat, and Resourcesat, collectively enhancing India’s Earth observation capabilities.
Previous RISAT satellites have played a significant role in critical missions. They provided crucial imagery for India’s surgical strikes in 2016 in Pakistan-occupied Kashmir (PoK) and the 2019 Balakot airstrike, facilitating real-time planning and execution of these operations.
