超小型无人机GPS/MIMU组合导航定位系统研究

Study of GPS/MIMU Integrated Navigation and Location Systems for SUAV

在考虑超小型无人机特点及其对导航定位需求的基础上,研究了利用微型惯性测量单元(MIMU)和GPS-OEM板,设计出一种低成本、轻小型的GPS/MIMU组合导航定位系统。为了验证该系统的性能,利用MIMU和GPS观测数据对该组合系统进行了仿真。仿真结果表明,组合导航系统在精度和可靠性方面,较单一的导航系统都有明显的改善。

Based on the characteristic and the demands for navigation and location to SUAV, a low cost GPS/MIMU integrated navigation system is designed by using MIMU and GPS-OEM panel in this paper. In order to verify the performance of the integrated system, the simulation is implemented by using the actual data measured and observed. The simulation results show that the integrated navigation system can more greatly improve reliability and precision than the single navigation system.
