摘　　要：为加快捷联惯性导航/卫星定位组合导航系统(Strapdown Inertial Navigation System/Global Positioning System,SINS/GPS)从算法到硬件产品的实现过程,采用快速原型技术进行设计.该方法在1个统一的Matlab/Simulink开发环境中建立系统模型并进行数字仿真;借助RT-LAB快速原型开发平台和实时工作间(Real-Time Workshop,RTW)为系统模型自动生成代码并加载到目标机和DSP硬件;实现SINS/GPS组合导航系统DSP硬件在回路仿真的快速原型设计.系统实时仿真结果与数字仿真结果一致,表明其具有开发周期短、实时性能好等优点.To accelerate the development of Strapdown Inertial Navigation System/Global Positioning System（SINS/GPS） products from algorithm to hardware, the rapid prototype technology is used to design the system. The system model is designed and the digital simulation is done in a unified development environment of Matlab/Simulink. The code is automatically generated for the system model and loaded on the target machine and DSP hardware by using the rapid prototype development platform RT-LAB and Real-Time Workshop （RTW）. The rapid prototype design on DSP hardware-in-loop simulation of the SINS/GPS integrated navigation system is implemented. The real-time simulation result of rapid prototyping system is consistent with the digital simulation result. So the method has the advantages such as short development cycle, good real-time performance and so on.
