Neat and simple formulae for correcting tropospheric refraction effect aro presented in this paper. They can meet the needs of the positioning accuracy of the order of meter magnitude. At present time there are various models of the tropospheric refraotivity, in which the Hopfield's is the best, it is adopted here. In the satellite doppler positioning, the observations are discarded when the elevation of the satellite is under ten degrees. Thus the buckled parts of wave path do not effect on the positioning accuracy for the order of meter magnitude and then can be neglected.

本文提出了对流层折射改正的简化公式,可以满足米级精度的定位需要, 目前已有的关于对流层折射率的模型中,霍普费尔德的模型是比较好的,我们采用了这个模型.在卫星多普勒定位中,抛弃了卫星的仰角低于10°的观测资料,因此,波迹弯曲不影响米级定位精度,可以忽略。

This paper discusses the influence of an elevation error on the determination of longitude and latitude in two-dimensional positioning of satellite Doppler station. As a result, a method for the determination of three-dimensional coordinates of the station by means of multiple-pass two-dimensional solution is suggested. The results of computation show the effectiveness of the method.

本文讨论了在卫星多普勒二维定位中高程误差对测定测站经纬度的影响,并根据这些影响特性介绍了用多次卫星通过的二维定位解算方法定出测站的三维最佳值的方法。计算结果表明:其方法是有效的。

The researches in the photographic astrometry require to keep stabilization of teles" cope system, i. e. the proper positioning accuracy and precision of the telescope have n?variations. But they would have variations, if the optical and mechanical systems of the telescope were changed.

照相天体测量学研究要求望远镜所固有的定位准确度和精确度保持稳定。但是,由于望远镜光学系统及机械系统等的变化,从而导致望远镜固有的定位准确度和精确度发生变化。因此,需要定期对望远镜系统进行检验,以便了解望远镜系统的定位状况。本文叙述了统计检验方法,并选取了10张昴星团区域的底片,两期底片相隔约23年,对佘山40厘米赤道议作了检验,结果表明望远镜系统是稳定的,为我们今后利用40厘米赤道仪测定恒星自行及精密定位等研究工作提供参考。
