📋 Tender Overview
On August 8, the Ministry of Natural Resources held a completion acceptance meeting for the 22 star project and 02m/2m optical satellite (8) project in Beijing. The meeting pointed out that the two types of satellite projects have continuously strengthened the deep space earth observation capabilities, improved the backbone network of remote sensing satellites for the national civil space infrastructure, and have become the backbone of rapid access to national high-resolution stereoscopic images and quarterly changes in the national territory, and played a fundamental and strategic supporting role in implementing innovation-driven development strategies and promoting high-quality development of natural resources systems.
Academicians and experts in the field fully affirmed the results of the construction of the two types of satellite projects, believing that the satellite has been operating stably in orbit for many years, and a number of innovative breakthroughs have been achieved in engineering technology, breaking the monopoly of foreign satellite data, increasing the supply rate of "three-tone" domestic satellite image data to more than 90%, and promoting the operational application of China's land remote sensing satellites to a new level. The two satellites not only become "efficiency multipliers" for natural resources work, but also integrate the main business processes of emergency management, ecological environment, urban and rural construction, transportation, agriculture, forestry and water conservancy, etc., providing strong data guarantee and technical support for serving major national strategies.
It is reported that the resource-02 2016 satellite is the first remote sensing service satellite of the national civil space infrastructure development plan, and it is also the first operational satellite of China's first generation of civil high-resolution stereoscopic surveying and mapping satellite Resource No. 5 series satellites, which was launched on May 30, 12 and put into commercial application in December of that year. It is equipped with experimental laser altimetry payload for the first time, and after networking with similar satellites such as Resource 01 03 Star and Resource 1 5 Star, it can obtain high-resolution stereoscopic images and multispectral images covering the whole country and even the world faster, providing high-precision data guarantee for the production of 1:2,5 basic geographic information products nationwide, <>:<>,<> and larger scale map repair and update, real-world <>D China construction, natural resources survey and monitoring, etc., and supporting the completion of a new generation of digital elevation model construction. It realizes the digital orthophoto from irregular update to quarterly sequential acquisition and expression.
The 2m/8m optical satellite (3) is the first civil high-resolution optical land service constellation of the national civil space infrastructure development plan, and it is also the first batch of operational satellites launched after the establishment of the Ministry of Natural Resources, which was launched on March 2018, 3 in the form of "three stars with one arrow" and put into commercial application in October of that year. The single-star imaging width is greater than 31 kilometers, which can achieve 10-day global coverage of 60 stars and 3-day revisit. Its networking with satellites such as Gaofen-15 and Gaofen-2 has achieved quarterly effective coverage of 2-meter-level satellite images in the national land area and monthly effective coverage in the northern region, and has played an important role in the investigation and monitoring of the quality and ecological status of natural resources in the country, the dynamic monitoring of "non-agriculture" and "non-grain" of cultivated land, land law enforcement, geological survey and other work.
Wu Wenzhong, chief planner of the Ministry of Natural Resources, said that in the next step, the Ministry of Natural Resources will work with various departments to promote the development and construction of the 14th Five-Year Plan land and sea observation satellite project in accordance with the national civil space infrastructure development plan and maintain stable and sustainable Earth observation capabilities. Deepen the innovation of satellite application technology, continuously improve the independent application product system, and do a good job in the standardization of satellite applications. Actively promote the innovation of satellite remote sensing applications, strengthen the development of key technologies, focus on the positioning of natural resources work of "strictly abide by the bottom line of resource security, optimize the spatial pattern of national territory, promote green and low-carbon development, and safeguard the rights and interests of resource assets", expand the efficiency of operational applications, and better support the "two unification" responsibilities and high-quality development of natural resources.
The National Development and Reform Commission, the State Administration of Science, Technology and Industry for National Defense, the Ministry of Housing and Urban-Rural Development, the Ministry of Transport, the Ministry of Agriculture and Rural Affairs, the Ministry of Emergency Management, the State Forestry and Grassland Administration, the Chinese Academy of Sciences, the China Aerospace Science and Technology Corporation and other departments and units, as well as the directors of major systems of satellite, launch vehicle, ground and other engineering projects and representatives of participating units attended the meeting.
