基于“即插即用”技术的无人机机载卫星导航设备的自动识别

Auto-recognition of Satellite Navigation Equipment Onboard for UAVs Based on PnP Technique

针对某型无人机使用的几种卫星导航设备,导航系统硬件设计采用通用一致接口,软件设计了自动识别功能,实现对不同接收机的"即插即用"。改变了以往机载导航系统软件版本随外接接收机类型的不同而不断换版的现象。满足了无人机系统在不同试验阶段对不同性能、不同成本的卫星导航设备配置的需求。并对其在系统长期静态、动态试验中出现的问题提出了有效的解决措施。

Through adopting the same common interface in hardware design and designing the auto-recognition function in software, the three different kinds of satellite navigation equipments can be ＂plug and play＂ in the navigation system for the UAV. The situation that the navigation software version was changed with the different kind of receiver onboard does not exist now. The design satisfies the need of installing the receivers with different features in precision and cost for the UAV during different testing phases. It also put forward very effective methods for solving the relevant problems which were appeared during the long period of the ground and flight tests.
