地理坐标系 meaning in English
geographic coordinate system
Examples
- Geographical co - ordinate system
地理坐标系统 - As a sub - problem involved in the new navigation algorithm , the transformation from earth - centered earth - fixed coordinates to geodetic coordinates is addressed
4 .研究了新导航算法中所涉及的一个子问题? ?从地球坐标系到当地地理坐标系的坐标变换问题。 - It uses the longitude and latitude geographic coordinate system to fix the position relationship among the radio systems and their interface to the electronic map database and has researched on the related problem
为了确定系统间相互位置关系及与电子地图数据库的接口,采用地心经纬度地理坐标系,并研究了相关的定位问题。 - Initial alignment is to put on some speed of control angel in order to transferring the maths platform to expected location . it can be controlled by error equation . in the platform system , it used to adopt the modern control theory method
初始对准从控制上讲就是施加一定的控制角速度把数学平台转向期望的位置(与地理坐标系重合) ，它是按误差方程进行控制的，过去在平台系统中采用频率特性方法，目前已经采用了现代控制理论设计方法。 - A new model was presented in a three dimensional geographic coodinate system to describe the linear growth of r - t instability so that the effects of magnetic inclination and declination were taken into accont . it is an generalization of former theories from equatorial to mid - latitude regions . from this model one can see the influence of magnetic strength , inclination and declination . due to the magnetic effects , the occurrence rate of the instability is not symmetric in longitudes even at the magnetic equator . some occurrence peaks or valleys will appear in certain places around the world
从三维地理坐标系出发建立模型，考虑了地磁倾角和偏角的影响，研究spread - f现象的全球分布特点，是对以前的研究从赤道地区向中低纬度地区的推广。从该三维模型中可以看到地磁场的大小和位型的影响包括磁倾角和磁偏角的效应。由于地磁位型的不同，发生率的分布并不具有经度对称性，即使在磁赤道附近也如此。
