China Gansu Net, July 8 (Northwest Corner, China Gansu Net Reporter Song Fangke) On July 8, at the 30th Lancha Fair, the Gansu Provincial Department of Water Resources and Aerospace Hongtu Information Technology Co., Ltd. signed a satellite naming agreement, and the first commercial water conservancy remote sensing satellite in Gansu Province will be launched at the Jiuquan Satellite Launch Center at the end of August this year.
The "Longyuan Water Conservancy-1" satellite is the first commercial remote sensing satellite serving the provincial water conservancy department, with the characteristics of provincial coverage, dynamic monitoring, precise positioning, situational awareness, etc., to help the construction of digital twin water conservancy.
The satellite has wide-format imaging capabilities, and the coverage area of a single remote sensing image can reach 100*100km2, which can meet the rapid coverage of remote sensing images in the whole province. In addition, the satellite can be customized on demand, and emergency dispatch can be carried out after determining the target area to meet the needs of emergency monitoring.
At the same time, the "Longyuan Water Conservancy No. 1" satellite is a radar satellite, and the data collection is not affected by cloud and rain weather, which is an ideal data source for water conservancy business. After the networking with the same series of satellites is completed, flood disaster monitoring and dynamic monitoring of surface water resources can be gradually realized once a day or even once an hour.
The Longyuan Water Conservancy No. 1 satellite also has high-resolution imaging capabilities, with a maximum resolution of 0.5m in remote sensing images, which can accurately obtain the location and range of water conservancy objects with an area greater than 3m².
Niu Jun, Secretary of the Party Leadership Group and Director of the Gansu Provincial Department of Water Resources, said that at present, Gansu Province is speeding up the construction of meteorological satellites, rain measurement radars, rain gauge stations, and hydrological stations to form the "three lines of defense" for rainwater monitoring and forecasting, and vigorously implement the construction of smart water conservancy. Aerospace Hongtu Company is a leading satellite Internet company in China, with rich experience in the fields of flood and drought disaster early warning and forecasting, water conservancy digital twin, and water conservancy safety supervision, with obvious technical advantages. The signing of this strategic cooperation agreement is an organic combination of "water conservancy needs" and "enterprise capabilities", which can be said to be timely and timely. In particular, the "Longyuan Water Conservancy No. 1" satellite is the first commercial remote sensing satellite serving the provincial water conservancy department in China, with the characteristics of dynamic monitoring, precise positioning, situational awareness, etc., which will greatly help Gansu Province improve the modern rainwater monitoring and forecasting system and improve the level of water conservancy informatization in the province.
According to reports, the "Longyuan Water Conservancy No. 1" satellite is one of the radar satellites of the first phase of the "Nuwa Constellation" project that plans to launch 54 operational satellites, and the first batch of 4 radar remote sensing satellites has been successfully launched at the Taiyuan Satellite Launch Center on March 30, 2023.
The "Longyuan Water Conservancy No. 1" satellite is expected to be launched at the Jiuquan Satellite Launch Center at the end of August this year, followed by the "Longyuan Water Conservancy No. 2" satellite, after the two satellites are networked, it will accurately locate and dynamically detect the water conservancy system in Gansu Province, and escort the high-quality development of the water conservancy system with intelligence and digitalization.
