A new method to estimate the aircraft heading angle, wind velocity, and airspeed bias error is proposed without relying on the magnetometer. A GPS, rate-gyro, pitot-static tube, and sideslip angle sensor are combined through a design of an extended Kalman filter based on a vectorial geometric relation among the ground, air, and wind velocity. The feasibility of the method is validated through a desktop simulation. The flight test is conducted utilizing the estimated yaw angle as a guidance variable to evaluate the performance of the method. The estimated wind information is compared to the automatic weather system nearby.

固定翼无人机包括风速的方向轴估计

提出了一种不依赖磁力计来估计飞机航向角,风速和空速偏差误差的新方法。通过基于地面,空气和风速之间的矢量几何关系,通过扩展卡尔曼滤波器的设计,将GPS,速率陀螺仪,皮托管和侧滑角传感器组合在一起。通过桌面仿真验证了该方法的可行性。使用估计的偏航角作为指导变量进行飞行测试,以评估该方法的性能。将估计的风信息与附近的自动气象系统进行比较。
