单天线GPS接收机载体姿态测定分析

该文研究了利用单天线GPS接收机的输出信息来实时确定载体姿态的基本原理与方法。文中的GPS载体姿态是指关于载体飞行速度矢量轴的新系偏航角、航迹角和新系滚转角，亦称为新系姿态。文中对姿态测定的分析包括利用GPS接收机配合软件LABMON46输出的原始信息来分析速度矢量的求解方案；利用卡而曼滤波模型对速度信息进行处理得到相应的加速度信息；根据前面2步求得的速度和加速度给出解算载体新系姿态的方法；最后给出常规姿态与新系姿态的关系和对照说明。

Attitude Determination with Single-antenna GPS Receiver

The principle and method of aircraft attitude determination with the information given by single antenna GPS receiver are discussed . The attitude mentioned in the paper is also called as pseudo attitude. It consists of flight path angle to the local horizontal plane and roll angle about the aircraft velocity vector axis. There are four major sections in this paper: to achieve the velocity vector by analyzing the information given by the GPS receiver; to estimate acceleration vector using a Kalman filter model with the velocity vector information; the attitude synthesizing algorithm model; the relation and contrast of traditional attitude and pseudo attitude.
