| 摘 要： | 研究利用GPS技术间接获取正常高，对铁路测量具有非常重要的实用意义。用BP人工神经网络，对京沪高速铁路某段实测GPS大地高程数据进行了转换计算，得到了比较高的转换精度，结果也是稳定的。经过与其它常用方法进行对比，表明利用人工神经网络进行带状测区GPS大地高到正常高的转换计算是可行的。

| Abstract: | The study of obtaining normal height by using GPS geodetic height indirectly is of important significance in railway survey. In this paper some GPS geodetic heights of Jing - Hu High - speed Railway are transformed to normal height by means of the BP Artificial Nerve Network, the result of which is both precise and steady. A comparing with other common methods indicates that it is practicable to transform GPS geodetic height to normal height with ANN in long belt area. |
