UAV flight safety is the first issue of the UAV's attention. The establishment of a UAV flight monitoring system not only meets the needs of the army but also has important significance. This paper introduces the development status and trends of aircraft fault prediction and health management at home and abroad. The key technologies of UAV flight monitoring system are analyzed, Including flight state...
According to actual QAR data which can reflect flight safety, a new method of flight operation safety on event margin was proposed. And a model for event margin was established based on flight safety monitoring standard. By quantitative analysis event margin of parameters, it can be used to evaluate flight safety, and it can help to reconstruct operation morphology. Furthermore, it widens research...
The snow-covered information, including snow-covered area, snow depth and snow water equivalent have been extracted from the remote sensing imagery of CBERS-02 satellite over the area of Jiaodong Peninsula in west Shandong Province, one of the snowiest regions in China. Based on the pre-processing of remote sensing data of CBERS-02 imagery, the statistical analysis of spectral characteristics has...
