摘　　要：利用超短基线进行载体姿态测量,可以实现载体的航向及姿态的测量。利用两片GPS OEM板同步载波相位观测,对姿态进行测量,不仅成本低,而且可以提供较高的精度,基本满足船舶导向的需要。从船舶姿态测量的实时性出发,对船舶的精确方位及姿态测定进行了算法研究,给出了船舶测姿系统的设计思路和信息处理过程,搭建了船舶姿态测量系统。该系统适用于静态、低动态载体的姿态测量与定位。The research of the carriers＇ orientation and attitude are based on the carrrier phase observation of two GPS OEM boards, in this paper, from the requirements of real-time determination of moving carrier＇s attitude, the GPS carrier phase differential technique is presented, meanwhile, the design thought of system and basic procedure of information processing are introduced in detail. Real-time determination of carrier＇ s attitude is achieved and the basic technical indexes are met. This system is fit for attitude determination of static carrier and dynamic carrier at middle and slow speeds.
