[ China Instrument Network Instrument Development ] On October 25, 2018, the Ministry of Science and Technology organized a national 863 program major project “Star Grid Comprehensive Quantitative Remote Sensing System and Application Demonstration (Phase I), (Phase II)†in Beijing.
The comprehensive quantitative remote sensing of satellite planes is an important way to give full play to satellite, aviation and ground coordinated Earth observation capabilities, and to improve the quantitative acquisition and application of remote sensing data. It is also an inevitable trend in the development of international Earth observation.
In China, the Ministry of Science and Technology has taken the construction of integrated quantitative remote sensing systems and application demonstration projects as one of the four priority development themes in the field of Earth observation and navigation technology. The project will focus on the key technologies of satellite-ground coordinated observation and satellite networking, and capture key technologies such as rapid quantitative process processing of multi-scale space-time remote sensing data, comprehensive quantitative remote sensing product generation and authenticity testing based on satellite networking and virtual constellation, and realize events. Driven remote sensing data proactive services, as well as operational services for resource and environmental remote sensing information.
Among them, the overall supporting units of the first and second phases of the project are the Institute of Remote Sensing and Digital Earth of the Chinese Academy of Sciences. The first phase of the project from January 2012 to June 2015, with a total funding of 96.12 million yuan, includes 11 topics, including 4 topics for remote sensing Earth; the second phase of the project from January 2013 to June 2016, with a total funding of 37.1 million. Yuan contains three topics, of which two topics are handled by remote sensing Earth.
In 2015, the project has broken through the remote sensing application-oriented multi-star coupling network imaging planning and multi-source data active services, surface parameters multi-source remote sensing collaborative inversion and pixel-scale true value acquisition, etc., in the international arena. It is the first to realize the leap from the single sensor quantitative remote sensing product production system to the multi-star collaborative inversion production system that does not depend on specific sensors for quantitative remote sensing products.
On October 25, 2018, the acceptance experts listened to the project summary report, watched the results and system demonstrations, and reviewed the relevant materials. After questioning and discussion, the acceptance expert group believes that the first and second phases of the project have completed the research content and assessment indicators specified in the project notification, and passed the acceptance.
This time, the breakthrough of the “Star Quantitative Integrated Remote Sensing System and Application Demonstration†project will promote China's mineral resources, regional rivers, grain production, forest resources and ecological environment, as well as other application areas that are critical to China's social and economic sustainable development. The global monitoring capability provides important scientific and technological support for spatial data and information products for major applications such as the Global Eco-environment Remote Sensing Monitoring Report, the Digital One Belt and One Road, the National Integrated Earth Observation Data Sharing Platform, and the Hainan Province and the South China Sea Spatial Big Data Center.
