查询词典 azimuth

In this paper, the basic mathematical model was derived by means of two methods, the first is the twostar positioning algorithm in celestial navigation theory and the second is based on the gyro dynamics theory. The results from these two methods are identical and therefore are correct. The latitude is equal to the elevation-angle of the polar gyro. The course is the ideal output from the sensor fitted to the outer gimbal. The longitude is a function of the equator gyro's azimuth and elevation angles.

本论文用天文导航中的双星定位法和经典的陀螺力学原理两种方法建立了ESGM的基本数学模型，并且得到一致的结果，说明所建模型是正确的，即载体的纬度等于极轴陀螺主轴相对水平面的高度角，载体的航向等于极轴陀螺外环轴上角度传感器的理想输出，载体的经度是赤道陀螺的方位角和高度角的函数。
