Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of navigation and positioning, and particularly relates to a low-altitude flight safety situation service system and method based on WebGIS. Background Art
[0002] The low-altitude economy is becoming an important part of the future intelligent social development in our country and will play an important role in aspects such as urban safety supervision, low-altitude logistics, disaster prevention and control, surveillance and tracking, etc., with broad prospects for industrial development.
[0003] Flight safety is particularly important for the development of the low-altitude economy, which requires aircraft to have reliable situation awareness and stable control capabilities. Large and high-value unmanned / manned aircraft usually integrate multi-mode navigation and positioning, communication and control units, and have good anti-wind flight qualities; but for most small and medium-sized unmanned aircraft, they usually only have satellite navigation and video transmission remote control links, and the anti-wind ability is relatively limited. Currently, the urban electromagnetic environment is becoming increasingly complex, the local low-altitude airflows change greatly, and there is a lack of information interaction among unmanned aircraft. There is no service system that can present the flight safety situation distribution in the low-altitude airspace to the operator. Unmanned aircraft operators can only operate unmanned aircraft through experience and real-time video transmission. Once the communication and positioning are disturbed and interrupted or they encounter strong winds, they will be helpless. In recent years, crashes have been frequent, and there is an urgent need in the market for a system and service software that allows users to obtain the flight safety situation in the low-altitude airspace in real time and intuitively through mobile phones or computers. Summary of the Invention
