South Korea launches first agriculture-dedicated satellite

South Korea has successfully launched its first agriculture-dedicated national satellite, which will observe farmland and crops across the country every three days and help shift agricultural policy — from crop supply management to direct payment programs and disaster response — onto a data-driven footing.

The Ministry of Agriculture, Food and Rural Affairs and the Rural Development Administration announced Wednesday that the agriculture and forestry satellite, designated Next-Generation Medium Satellite 4, had been successfully launched. The satellite was jointly developed with the Korea AeroSpace Administration and the Korea Forest Service.

The satellite is South Korea's first national satellite dedicated exclusively to agriculture and forestry observation. Equipped with 5-meter resolution and a 120-kilometer observation swath, it will photograph farmland and crops nationwide every three days. The launch establishes a foundation for securing stable, Korea-specific satellite data, ending the country's reliance on foreign satellites for agricultural observation.

Once fully operational, the satellite will transform how the government manages crop supply. It will continuously monitor the cultivation area of supply-sensitive crops such as cabbage and onions, and track the growth of staple crops including rice and soybeans. By combining satellite imagery with AI analysis, the government aims to improve output forecasts and respond proactively to sharp price swings in agricultural commodities.

The satellite will also sharpen management of the public benefit direct payment program and farmland oversight. By analyzing farmland nationwide down to individual plots, authorities will be able to continuously verify whether land is being cultivated, left fallow or converted to other uses — reducing the burden of on-site inspections. Registration data for agricultural business entities will be verified remotely to help prevent fraudulent subsidy claims.

Agricultural disaster response will also become faster. The satellite will enable rapid, wide-area detection of damage from pests, drought, heavy rainfall, flooding and lodging, supporting damage assessments and recovery planning. Continuous monitoring of reservoirs and irrigation infrastructure is expected to improve the efficiency of agricultural water management.

Rural spatial management will grow more precise as well. The government plans to periodically check the distribution of facilities, landscape changes, illegal land filling and unauthorized structures at the city, county, town and township level to improve the accuracy of rural spatial planning and management.

Private-sector access to satellite data will be opened in stages. The government will release the data incrementally to support smart farming, crop growth monitoring and the development of data-based agricultural services. Plans are also underway to develop a "Korean agricultural AI foundation model" that integrates satellite imagery with meteorological, soil and environmental data.

The Rural Development Administration plans to produce 51 types of agricultural satellite information by fusing AI analysis technology with meteorological, spatial and field data from satellite imagery. The data will be released in stages and will cover crop cultivation and harvest areas, growth conditions, farmland changes, and agricultural disaster information including pest outbreaks, flooding and drought.

"The launch of the agriculture and forestry satellite enables us to build a data-based decision-making framework across core agricultural policy areas — crop supply management, the public benefit direct payment program and agricultural disaster response," said Kim Jeong-uk, director general for agro-industry innovation policy at the Ministry of Agriculture, Food and Rural Affairs. "We will deliver tangible results in science-based agricultural policy that the public can feel."

Rural Development Administration chief Lee Seung-don said the satellite had laid the groundwork for continuous nationwide observation of farmland and crops. "We will provide agricultural satellite information that the field demands in a phased manner and push ahead without delay on introducing follow-on satellites," he said.

Meanwhile, the satellite lifted off Tuesday at 4:12 p.m. Korean Standard Time from Vandenberg Space Force Base in California. About two and a half hours after launch, it successfully separated from its launch vehicle at an altitude of approximately 888 kilometers. At 7:05 p.m. it made first contact with the ground station at Svalbard, Norway, and at 10:50 p.m. it completed its first communication with the Korea Aerospace Research Institute ground station in Daejeon. After an initial commissioning period, the satellite will begin providing data in full for agricultural and forestry observation and disaster response — including wildfires — next year.
