Description: 本程序提供WGS-84、BJ54和Xi’an80下大地坐标、空间直角坐标以及高斯坐标的相互转换，不同椭球参数下的转换需通过空间直角坐标过渡，由于时间原因，高斯坐标正反算只在BJ54下进行。空间坐标的转换需要借助七参数，可手工输入，也可由文本文件中至少公共点平差计算得到（data.txt可用于七参数计算测试）。 计算过程： WGS-84 B=30.303622 L=114.212196 H =47.36 （经纬度采用度分秒联写） BLH ——>XYZ X=-2268156.8016 Y=5010324.6053 Z=3219239.5885 WGS-84 XYZ ——> BJ54 XYZ ( 参数均设为0, 值不变) BJ54 XYZ——> BLH B =30.303614 L=114.212196 H= -61.3351 BLH ——> xyH x=3376768.6854 y=534182.3886 H不变 (出于正反算方便的考虑，没有在y前加三度带投影带数，这里由中央子午线114可知为38，即y=38534182.3886)

Description: 一般的GPS数据处理软件都是采用上述步骤进行计算的，其中只有第2步涉及转换参数。鉴于我国曾使用不同的坐标基准（BJ54、State80、 Correct54），各地的重力值又有很大差异，所以很难确定一套适合全国且精度较好的转换参数。通行的做法是：在工作区内找三个以上的已知点，利用已 知坐标和所测Wgs84坐标，求解七参数。若多选几个已知点，通过平差的方法可以获得较好的精度。 -General GPS data processing software are used in calculating the above steps, only Step 2 involves the conversion parameters. In view of our country have been benchmarks for the use of different coordinates (BJ54, State80, Correct54), around the gravity value, and very different, so it is difficult to determine the accuracy of a better suited to the country and the conversion parameters. Practice is: to find in the work area more than three known points, using the known coordinates and measured coordinates Wgs84, solving seven parameters. If more than a few known points selected by the method of adjustment can be a better accuracy.
