摘要
随着GPS应用的普及,高斯投影在测量中出现的机会越来越多。许多文献上都给出了推导过程,这个推导过程的运算量是非常大的,而且计算精度难于提高。经过研究,一种易于编程的递推公式被发现,虽然这个公式在计算量上没有减少,但是可以较好地解决精度问题。
With the application of GPS technology, Gauss projection is applied widely in surveying. Its recursion is given out in many papers. Generally, there are two problems in this recursion, which are complexity and low precision. A new method, which is easily implemented by programming and can improve calculation precision, is proposed in this paper, although the recursion is also properly complex.
