摘要
由于传统的卫星导航系统容易受到干扰和遮挡,惯性导航存在误差积累的缺陷。为了提高定位导航授时服务质量,提出一种基于微惯性测量单元(MIMU)、芯片原子钟(CSAC)和北斗卫星导航(BDS)模块的组合导航微系统硬件设计方案,介绍了它们的硬件特征与配置设计,完成了组合导航微系统底层驱动设计。实验表明:组合导航微系统在真实路段跑车试验可以得到准确的位置和速度等信息。此外,组合导航微系统在最大速度为8km/s,最大加速度为50g的高动态仿真环境中,仍能保持较高的导航精度和跟踪性能。
Traditional satellite navigation systems are vulnerable to jamming and shielding,and the inertial navigation system has existing the problem of error accumulation. In order to improve the quality of PNT services,a micro integrated navigation system hardware design is presented,which is based on the miniature inertial measurement unit（ MIMU）,chip-scale atomic clock（ CSAC） and Beidou satellite navigation system（ BDS）. The hardware features and configuration design of MIMU,CSAC and Beidou navigation module are introduced,and the bottom-driven design of integrated navigation micro system is completed. The experimental results show that integrated navigation micro system can obtain accurate location and velocity information in field test. In addition,it can maintain high navigation precision and tracking performance in the high dynamic simulation environment by a maximum speed of 8 km/s and acceleration of50 g.
