In order to decrease the weight of tracking system and make suitable use of the Lander space, the pitching-axis of Lunar optical telescope is vertical with the Lander's flank, its rotation part is fastened on the Lander's flank, the azimuth-axis adopts rotation reflecting mirror, the flat mirror is located before the telescope tube, the angle of flat mirror and the telescope ray-axis is 45°,so that the reflecting ray can enter the telescope optical system, the scan of the mirror can be accomplished by the rotation of the telescope tube.

工作过程中望远镜支架的两个轴需带动望远镜一起转动，为了减小跟踪平台的重量和合理利用着陆器空间，又能在大范围内对太空目标进行跟踪，月基天文望远镜的俯仰轴垂直于着陆器的侧面，其转动部分固联在着陆器的侧面，方位轴采用旋转反射镜方式，将平面反射镜放在望远镜的镜筒前端，并与望远镜光轴成45°安装，使反射光线能够进入望远镜光学系统，通过转动望远镜镜筒使得反射镜实现对空间的扫描。

In order to improve the monitoring precision and resolution of tropospheric zenith delay, the hybrid approach, using a batch least squares estimator but parameterizing the zenith delay by a linear spline with knots at 30-minute intervals and treating the knots as a Gauss-Markov process, is employed to deal with the tropospheric zenith delay.

为了提高对流层天顶延迟的监测精度和分辨率，我们采用了分段的参数估计和随机过程相结合的估算方法来处理对流层延迟，由此获得了分辨率分别为2 h和30 min，精度好于1 cm的天顶延迟量。

To get the observer's Lat.and Long.just by pressing a button without the sea horizon to turn to,we should know clearly the relationship between the accuracy of zenith distance observed and the accuracy of a position fixed,the causes of the errors of zenith distance observed,what accuracy of zenith distance observed could be obtained and what accuracy standard should be used.

要在无水天线测天时一按按钮就可定出较精确的船位经纬度，必须弄清天体顶距测量精度对定位精度的影响，弄清顶距测量误差产生的原因，可达到的精度及选用适当的精度标准。
