摘要
针对实际工程要求,设计适用于低精度光纤陀螺的组合导航系统的试飞方法。构建一种基于低精度光纤陀螺的组合导航系统,包括磁传感器、多普勒雷达和卫星导航子系统,设计Kalman滤波器,给出其状态方程和量测方程,并进行飞行试验。试验结果表明:该组合导航系统满足中等精度导航需求,设计成本较低,算法科学可行,具有较强的实用性,可广泛应用于各种民用航空导航领域。
Aiming at the practical engineering requirement, design the flight test method for integrated navigation system based on low precision fiber optic gyroscope. Establish integrated navigation system based on low precision fiber optic gyroscope, including magnetic sensor, Doppler radar, and satellite navigation subsystem, design Kalman filter. Put forward the status equation and measurement equation, and carry out flight test. The test results show that the integrated navigation system can satisfy medium precision navigation requirements, with low design cost, and the system algorithm is scientific and feasible. The system is practical and can be widely used in civil aviation navigation field.
