South Korea's first agricultural satellite set to launch Tuesday

South Korea's first dedicated agricultural and forestry satellite is set to launch Tuesday. Once fully operational, the satellite — which will photograph the entire Korean Peninsula every three days — is expected to transform agricultural policy across the board, from farmland surveys and public payment scheme monitoring to crop supply management and responses to wildfires and flooding.

The Ministry of Agriculture, Food and Rural Affairs announced Saturday that the agricultural and forestry satellite, designated next-generation medium satellite No. 4, will lift off at 4:10 p.m. Tuesday (Korean Standard Time) from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket.

The satellite is the first agricultural and forestry-specific satellite South Korea has developed using its own technology. Equipped with a 5-meter resolution and a 120-kilometer observation swath, it can photograph the entire Korean Peninsula every three days. It also carries five spectral bands capable of precisely analyzing the growth of crops and forests.

Until now, South Korea has had to rely on foreign satellite imagery or share data through cooperative arrangements. The new satellite will allow the country to obtain imagery tailored to its own agricultural environment on a stable, independent basis for use in policy decisions.

Farmland management is the area expected to see the most immediate change.

The satellite will repeatedly photograph agricultural land nationwide at a wide-area scale to verify whether fields are actually being cultivated. By combining satellite imagery with AI, the system will automatically detect uncultivated plots, unauthorized facility installations and conversions to forest land, then flag only those sites for on-the-ground inspection. The ministry expects the approach to improve the accuracy of compliance checks under the public direct payment scheme and agricultural business entity management, while also reducing fraudulent benefit claims.

Crop supply management will also become significantly more precise.

The satellite will continuously monitor vegetable cultivation areas and the growth of major food crops such as rice and soybeans to forecast output, giving the government a foundation to proactively manage supply and demand for price-volatile commodities. The ministry also plans to use the satellite to detect pest and disease outbreaks caused by abnormal weather at an early stage, enabling faster control responses.

Disaster response will also accelerate.

The satellite will repeatedly observe reservoirs, agricultural water facilities and flooded farmland to quickly assess the scale of damage. Wide-area analysis of forest damage from wildfires, landslides and pest infestations will support recovery decision-making. Damage maps generated immediately after a disaster will be shared with relevant agencies to help secure the critical window for recovery operations.

The satellite's applications will also extend to rural spatial management.

Satellite imagery will enable periodic monitoring of facility distribution, landscape changes, vegetation shifts, large-scale illegal land filling and unauthorized construction at the city, county, township and village level. Rural spatial planning and management are expected to become more systematic as a result.

Private-sector use will expand as well.

The Ministry of Agriculture, Food and Rural Affairs plans to open satellite data to the private sector in stages, supporting companies in developing crop monitoring, autonomous farming and data-driven services. The ministry is also pursuing development of a Korean agricultural AI foundation model that combines satellite imagery with meteorological, soil, environmental and crop data. Forecasts for flowering and autumn foliage seasons will be refined down to the neighborhood level.

The ministry will operate a policy consultative body on agricultural and forestry satellite utilization, bringing together the Rural Development Administration, the Korea Forest Service and private experts to maximize the satellite's applications. It also plans to link the satellite with the Ministry of Land, Infrastructure and Transport's land observation satellite to continuously improve the usability and quality of satellite data.

Kim Jeong-wook, director general for agricultural industry innovation policy at the ministry, said the launch marks a significant step toward building an independent agricultural information-gathering system that no longer depends on foreign satellite imagery. "We will establish a data-driven decision-making framework with precision and timeliness across core agricultural policy areas — including farmland surveys, direct payments, crop supply management and disaster response — to deliver science-based agricultural governance that citizens can feel in their daily lives," he said.
