基于双DSP的SINS/GPS组合导航计算机系统

摘要

为满足SINS/GPS组合导航系统对实时性、精度的要求,设计了一种基于双DSP的高性能SINS/GPS组合导航计算机系统.本系统按功能划分为数据传输子系统和导航计算子系统.选用高性能数字信号处理器TMS320F28335(DSP1)和TMS320C6713 (DSP2)分别作为数据传输子系统,导航计算子系统的核心处理器；两子系统之间通过双口RAM实现高速可靠通信.系统通过扩展外部接口实现对惯性组件数据,GPS数据实时采集,并输出导航参数,具有很强的实时性.%A high performance computer system for integrated navigation based on dual DSP was designed to satisfy the reuqirements of real-time performance,accuracy.The system can be divided into two parts:data transmission subsystem and navigation computing subsystem.TMS320F28335 (DSP1)and TMS320C6713 (DSP2)were selected as core processors for the data transmissio subsystem and navigation calculation subsystem.Dualsubsystems can make fast and reliable communication by shared dual pert ram.The system can access IMU data and GPS data in real time,also output navigation results by extending the external interface.
