参考椭球坐标系转换模型研究
本论文主要研究了大地坐标与空间直角坐标的互相转换、高斯投影坐标计算以及七参数法坐标转换。大地坐标与空间直角坐标的互相转换主要介绍了迭代法和非迭代法两种方法。高斯投影坐标计算中介绍了高斯投影坐标正算公式、高斯投影坐标反算公式、高斯投影坐标正算的数值公式以及高斯投影坐标反算的迭代计算公式。在不同参考椭球转换模型中主要介绍了七参数法，以及如何求解七参数，推导出了一些转换公式，并在七参数已知的情况下如何求解已知点在新的坐标系下的坐标。论文第四章还在MATLAB编程的环境下对一些实测数据进行了计算，通过对一些数据的对比分析来检验编程的正确性。

Abstract With the continuous development of surveying and mapping technology in the world, more and more demands the unity of the national surveying and mapping data, so to realize the conversion between different measuring coordinate system is of great significance, for the reference ellipsoid coordinate system transformation model research also appears very important. Based on the basic theory, introduced this topic research background, purpose and significance, as well as some scholars at home and abroad for related to this topic research present situation.
This thesis mainly studies the geodetic coordinate and space rectangular coordinate transformation to each other, coordinate calculation of gauss projection and seven parameters method of coordinate transformation. Geodetic coordinate and space rectangular coordinate transformation mainly introduced each other iterative method and iterative method two kinds of methods. Gauss projection coordinates is introduced in the calculation of gauss projection coordinates are calculated by coordinates calculate formula, gauss projection formula, gauss projection coordinate are calculated by coordinates numerical formula and the gauss projection iterative calculation formula. In different reference ellipsoid transformation mainly introduced the seven parameters in the model method, and how to solve the seven parameters, some transformation formula is deduced, and the seven parameters under the condition of known how to solve the coordinates of known points in the new coordinate system. The fourth chapter is under the environment of MATLAB programming for some measured data was calculated, based on some data analysis to verify the correctness of the programming.
