Abstract

The geographical environment with low-altitude is complex. Ground mountain, tall buildings, communications tower, bridge across the river, the tall vegetation has a significant effect on low altitude fly. The technology of virtual navigation and collision warning system which based on satellite navigation and virtual geographic environment is an important technical guarantee for safety fly in low-altitude space. This paper analysed the characteristic of low-flying environment and its impact on safe flight. And designed a global virtual geographic environment data organization model based on global discrete three dimensional grid model combining with object-oriented data organization model. The way of subdivision, coding and object organization has been discussed, then designed the structure of the object in the model in low attitude environment. At last an algorithm for low-flying anti-collision warning was designed to prove use of this model.
