摘　　要：微机电系统的迅猛发展,使得固态传感器具有体积小、重量轻、成本低等特点,研究利用固态传感器来构建低成本、小型化的导航系统成为导航领域的热点之一。通过将捷联惯性导航系统、磁阻/加速度计测姿系统和全球定位系统结合在一起,形成了组合导航系统。静态测试表明,相比单一的导航系统,组合导航系统的性能有了较大的提高。With the rapid development of the micro-electro mechanical systems,the solid-state sensor has features of small-cubage,light-weight and low-cost.Designing the low-cost and miniature navigation system with the solid-state sensor has become one of the hotspots in the navigation field.The integrated navigation system included strapdown inertial navigation system,attitude reference system constructed by magnetoresistance and accelerometer and GPS is discussed.In addition,static experiments are executed on the system.The results indicate that the performance of the integrated navigation system is much better than the single navigation system.
