GPS在载体姿态测量中的应用

本文主要介绍利用ＧＰＳ进行勒体姿态测量的工作原理、有关技术及ＧＰＳ姿态测量系统的组成。利用ＧＰＳ测量姿态，精度不会随时间而降低，运用皮信号测量不涉及Ｐ码及Ｃ／Ａ码的具体结构，造反可用性（ＳＡ）和轨道误差及电离层折射误差可以忽略不计，比通过惯性猎取将更便宜、精度更高。在不远的将来，这种技术可望在某些领域代替惯性技术，或与惯性系统组合，成为一种新的高精度、高可靠性、成本低的导航系统。

The Application of GPS in the Determination of Attitude

The principle of attitude determination using GPS,the techniques concerned with it and the composition of the attitude determining system are discussed. The accuracy of attitude determining system using GPS doesn't debase with time,the measurement of GPS carrier phase doesn't deal with the P Code or C/A code,the errors caused by SA,orbit and ionosphere can be neglected,so the attitude determining system has a higher accuracy and lower cost than traditional inertial system. It will replace inertial system in some fields,and the combination of it with inertial system will become a high accuracy,high reliability and low cost navigation system.
