摘　　要：针对高动态和干扰环境下GPS接收机工作时存在的问题,研究了SINS/GPS四种典型组合模式的工作机理,从系统的动态适应性和抗干扰性等方面对各组合模式的特点进行了深入分析;最后,从抗干扰能力、精度、快速性及鲁棒性等方面对其中两种代表性组合导航模式的性能进行了详细的仿真验证与比较,并给出了可供工程参考应用的建议。Aiming at the problems of GPS receivers working in high dynamic and jamming environments, the working mechanisms of four typical SINS/GPS coupled modes are studied, and the characteristics of each coupled mode are analyzed thoroughly from dynamic adaptability and anti-jamming performance. Finally, the simulations are implemented to validate and compare the performance of the two representative coupled modes including anti-jamming capability, precision, rapidity, robustness and so on, and the conclusions could be consulted and applied in practical projects.
