| Abstract: | 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. |
