This paper discusses in detail the range of lon gitude of ascending node of the orbits, by which point and area targets can be c o vered in different conditions by considering the disturbance of the earth shape J2 using a sphere triangle method, and provides a whole analytic expressio n.

利用球面三角方法详细讨论了在考虑地球形状J2项的摄动影响时，各种情况下能覆盖目标点的轨道的升交点经度范围，并将其推广到对区域目标的覆盖，给出了完整的解析表达式。

Since the storm heating intensities at the lower thermosphere resulting from energetic particles precipitated from the magnetosphere are different from area to area, the features of the ionospheric storm are also discrepant in different longitudinal chain regions.

特强磁暴引发的电离层暴是全球性的，但自磁层沉降的高能粒子对热层低部的加热程度及区域分布不同，因而各经度链区域内电离层暴的特征也有所差异。

格林威治以西第时区的时间，即西经度的时区，该时区包括西阿拉斯加和阿留申群岛。

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。

These images were placed in celestial latitude and longitude coordinate systems that allowed the positions of the stars to be mapped in the sky and formed the backdrop for predictions of the location of the planets and other heavenly bodies throughout the year.

这些图像被放置在天文经度和纬度坐标上允许明星的被映射在天空中并形成了全年的对行星和其他天体的位置预测系统的背景。
