摘　　要：介绍了基于微机械惯性器件和全球定位系统(GPS)的组合导航系统电路设计。根据组合导航系统工作的特点和控制的要求,设计了基于TMS320F2407的信息采集处理模块和基于TMS320VC33的组合导航计算模块,给出了以双口RAM作为共享存储器的设计方案。实际应用表明,该电路设计方案达到了导航系统的指标要求,并具有体积小、重量轻、功耗低、成本低等诸多优点。The design for the circuit of integrated navigation system based on micro inertial measurement unit and GPS is presented. In view of characteristics and requirements of the system, the module of data sampling and processing based on TMS320F24007 and the module of integrated navigation calculating based on TMS320VC33 are designed. A method based on dual-port RAM makes the communication between modules quick and credible. The results show that the design for circuit of integrated navigation satisfies the requirements of the system. The system has advantages of small volume, light weight, low power, low cost and so on.
