Korea's First Agricultural and Forestry Satellite Successfully Settles into Orbit...Ushering in the Era of Digital Agriculture and Forest Management with the 'Eye in Space' (Comprehensive)

Next-Generation Medium-Sized Satellite No. 4 Achieves First Communication with Korean Ground Station
Proving Domestic Standard Platform and Private Sector Satellite Development Capabilities... Boosting Satellite Export Competitiveness

The nation's first dedicated agricultural and forestry satellite has successfully completed its first communication with the Korean Peninsula from space and settled into its designated orbit. This marks the beginning of an era in which Korea can directly observe crop conditions, forest changes, and disasters such as wildfires and landslides using its own satellite. It is also significant as it once again proves the capabilities of Korea's domestically developed medium-sized satellite standard platform and the private sector-led satellite development.

The Korea Aerospace Administration (KASA), Rural Development Administration, and Korea Forest Service announced on July 7 that the Next-Generation Medium-Sized Satellite No. 4 (CAS500-4) succeeded in its first communication with the ground station at the Korea Aerospace Research Institute in Daejeon at 10:50 p.m. on the same day. Prior to this, the satellite had communicated three times with overseas ground stations, including Svalbard in Norway and King Sejong Station in Antarctica, and has now also established successful communication with a domestic ground station.

During this communication, the deployment of the solar panels and the condition of the satellite body were confirmed. Going forward, the initial operation procedures will be carried out sequentially, including the deployment of the X-band antenna and activation of the attitude control system actuators.

On this day at 4:12 p.m. (Korean time), Next-Generation Medium-Sized Satellite No. 4 was launched aboard SpaceX's Falcon 9 rocket from Vandenberg Space Force Base in California, USA. Approximately two hours and thirty minutes after launch, the satellite separated normally from the launch vehicle and entered a sun-synchronous orbit at an altitude of about 888 km, successfully making its first communication with an overseas ground station. About six hours and thirty-eight minutes after launch, it established a stable connection with the domestic ground station, marking the successful completion of all launch procedures.

The Falcon 9 rocket of SpaceX carrying the next-generation Medium-sized Satellite 4, developed as an agricultural and forestry satellite for agricultural and forestry management and forest change monitoring, was launched at 12:12 a.m. local time on the 7th from Vandenberg Space Force Base in California, USA.

Korea's First Agricultural and Forestry Satellite...Capturing the Entire Korean Peninsula Every Three Days

Next-Generation Medium-Sized Satellite No. 4 is Korea’s first dedicated satellite for agricultural and forestry observation. Developed based on a 500 kg-class standard platform with an actual weight of 514 kg, it is equipped with an optical payload capable of a 120 km swath and a spatial resolution of 5 meters.

It can capture images of the entire Korean Peninsula every three days, enabling precise analysis of crop growth and yield prediction, changes in farmland use, pest outbreaks, and flooding in reservoirs and farmland. In the forestry sector, it will provide continuous monitoring of forest fire and landslide damage, forest degradation, and ecological changes, and is expected to play a key role in climate change response and disaster management.

After approximately four months of initial operation and performance verification, the satellite will begin full-scale operations in 2027.

Lee Seung-don, Administrator of the Rural Development Administration, stated, "This success marks an important turning point from experience- and intuition-based agriculture to data-driven precision agriculture," adding, "We will further enhance yield prediction and response to agricultural disasters by integrating satellite imagery and AI."

Park Eunsik, Administrator of the Korea Forest Service, remarked, "This will serve as a foundation for proactive response to forest disasters such as wildfires and landslides, and for implementing scientific forest management."

Proving Private Sector Satellite Development Capabilities...Export Prospects Ahead

This achievement is significant not only for securing an agricultural and forestry satellite, but also for enhancing the competitiveness of the domestic satellite industry.

The Next-Generation Medium-Sized Satellite project aimed to secure a 500 kg-class standard platform to reduce satellite development time and costs and to establish a private sector-led mass production system. Korea Aerospace Industries (KAI) led the development of the third to fifth satellites in the series, and the fourth satellite was also developed primarily by private companies, from design and manufacturing to testing and verification.

In particular, the localization rate of the satellite body and payload components exceeded 75%, once again demonstrating Korea’s independent technological capabilities in satellite development.

The government plans to actively promote overseas market entry based on this standard platform, targeting countries such as Saudi Arabia, Peru, and Indonesia. The use of the standard platform enables faster and more economical production of customized satellites, which is expected to enhance Korea’s export competitiveness in medium-sized satellites.

Tae seog Oh, Administrator of the Korea Aerospace Administration (KASA), said, "This is an important achievement that has expanded private sector-led satellite development capabilities based on the 500 kg-class standard platform to a new level." He continued, "By independently securing satellite information required for agriculture, forestry, climate, and disaster response, we have greatly enhanced the nation's satellite information utilization capabilities and the competitiveness of the private satellite industry." He added, "We will continue to identify domestic and international satellite launch demand and further expand the use of Korean launch vehicles."
