Hanwha Systems has developed and launched a small synthetic aperture radar (SAR) satellite for Earth observation and intends to enhance its SAR technology to develop more satellites.
Speaking to Janes at the Korea Army International Defense Industry Exhibition (KADEX) 2024, held at Gyeryongdae from 2 to 6 October, a company official said it launched a SAR satellite from Jeju Island in December 2023.
This satellite can deliver 1 m-resolution images of areas of interest to the Republic of Korea (RoK) Armed Forces, the official said.
The official added that the satellite is expected to support intelligence, surveillance, and reconnaissance (ISR) operations of the RoK Armed Forces. Its primary objective is to monitor North Korean military activities.
“For example, images captured by the satellite can provide timely information to the RoK Armed Forces about suspicious North Korean military deployments and movements, ensuring military preparedness against possible threats,” the official said.
The satellite has a life cycle of three to five years, the official added.
According to the official, “Hanwha Systems is also collaborating with the South Korean government to develop a SAR satellite capable of delivering 0.5 m-resolution images. This satellite is expected to be launched by the end of 2026.”
In addition, Hanwha Systems plans to independently develop another SAR satellite that can produce 0.25 m-resolution images, the official added.
In April Hanwha Systems announced that it plans to “enhance its SAR satellite technology to capture images that identify more detailed features such as low-rise buildings and cars in urban centres, flora and fauna in forests, and maritime vessels in the sea”.
