Abstract: UAV remote sensing network system is an important part of the remote sensing system following satellite remote sensing network and airborne remote sensing network in China. UAV remote sensing system was scatteredly equipmented, widely used, lack of overall planning, so it is difficult to dispatch efficiently and configure reasonable, the effectiveness was degraded. It is unsafe for UAV remote sensing systems couldnt be supervised when it fly, because it was very small ,low and slow. Key technologies of UAV remote sensing network system based on Big Dipper Navigation Positioning System and GPRS/3G was researched in this 863 program that Ministry of Science and Technology organized in 2013 to take advantage of this new technology, improve its ability to innovate and emergency response. Operation and management mechanism UAV remote sensing network system was researched and series standards and codes was established in this paper, it made up the domestic blank of civilian UAV standards. This paper expounded the key technologies of UAV remote sensing network system based on Big Dipper Navigation Positioning System and GPRS/3G, It solved the problem of UAV remote sensing systems couldnt be supervised. This paper introduced the design thought of integrated operation management platform for UAV remote sensing network system. It provided technical support for co-ordinating scientific and technological resources, optimizing configuration, promoting sharing and comprehensive utilization. The key algorithms of building damage detection and construction of three-dimensional model was proposed, It laid the foundation of forming ability of UAV remote sensing data disaster assessment and establishing disaster emergency pilot. This paper discussed processing rapidly algorithms of UAV remote sensing data such as wallis filter. It provided the basis for developing UAV remote sensing data processing rapidly system. Through the key technologies research on operation and management mechanism UAV remote sensing network systems, flight control technology, integrated operation management platform, building damage detection and construction of three-dimensional model. It made a contribution for program ”Research on key technologies and demonstration of UAV remote sensing network system based on Big Dipper Navigation Positioning System and GPRS/3G”and provided the technical support for building social network demonstration system of UAV remote sensing.
