| 摘 要： | 姿态确定是ＧＰＳ在航天器上应用的一个重要方面。采用广义卡尔曼滤波（ＥＫＦ）方法利用ＧＰＳ进行航天器姿态确定，建立了ＧＰＳ载波相位观测和航天器姿态运动的线性误差方程，并进行了仿真计算。

| Abstract: | Attitude determination is a key aspect of Global Positioning System (GPS) use on spacecraft. Spacecraft attitude determination using GPS by Extended Kalman Filtering (EKF) is described in this paper. The linear error equations of GPS carrier phase measurement and spacecraft attitude kinematic are established, and simulation calculation is performed. |
