摘要
GPS空间定位系统利用卫星进行军事和民用定位与导航 ,其定位成果属于WGS 84坐标 ,而在区域工程测量中 ,常常采用的是地方坐标系 ,因而需要将WGS 84坐标转换为地方坐标。本文利用人工神经网络能够实现高度非线性的特点 ,设计出一种BP网络进行GPS坐标转换。通过与实际数据相比较 。
GPS is a global positioning system which is widely used in civil and military engineering, and its positioning results belong to WGS-84 coordinate system. As the local coordinate system is often used in engineering surveying, therefore, the system must be transferred into the local ones. This paper, utilizing the high nonlinear property of the artificial neural network, designs a BP network for GPS coordinates transformation. In comparison with the actual measurements, this method is proved to be effective in practice.
