摘　　要：航向测量仪(Vector Sensor)的作用就是为车载惯导系统初始化提供所必须的航向角;根据不同的应用环境和特性,用航向测量仪获取在各种条件下的航向角数据,通过对这些数据在精度、稳定性以及解算时间等性能上的对比分析,得到该仪器的最佳工作状态,进而获取该状态下的航向数据;通过实际的实验测试,此状态下的数据在精度和稳定性方面都能满足惯导系统的需求。Vector sensor can provide the navigation angle for the initialization of the inertial navigation system. According to different application conditions and peculiarity of vector sensor, many data about navigation angle needs to be gotten in many conditions, Through the contrast in precision, stability and the time spent getting navigation angle, we can receive the high-point of vector sensor, and we can get the navigation angle in this state. Then the navigation angle can satisfy the need of the inertial navigation system in precision, stability and the time to get the navigation angle during the test of the Inertial Navigation System.
