基于单天线GPS的伪姿态测量算法研究

Algorithm of Pseudo-Attitude Determination Based on Single Antenna GPS

介绍了根据单天线GPS速度测量值测定载体伪姿态的基本算法原理,建立了卡尔曼滤波方程,改进了伪航向角的计算和卡尔曼滤波模型,并进行了算法仿真。结果表明,在载体进行中高速飞行时,单天线测姿算法具有较高的精度,基本满足常规姿态测量要求。

The basic principle of determining pseudo-attitude based on the velocity measurement of single antenna GPS receiver is introduced,and the Kalman filtering equation is also established,and the calculation of pseudoheading angle and the Kalman Model are improved.Then we carry out algorithm simulation.The results show that when the carrier is in the medium and high speed flight,this pseudo-attitude algorithm has the higher accuracy,which basically meets the requirements for measuring conventional attitude.
