摘要
阐述了跨海高程传递的基本原理和方法,介绍了跨海高程传递数据采集及处理系统。跨距约10.5km的高程传递试验表明:基于三角高程的高程传递方法在跨距10km左右能够达到三等水准精度,严格的同步对向观测能够有效消除大气折光差的影响。
The basic principle and method of cross-ocean height transfer are illustrated;the data collection and processing system are introduced.The transfer experiment about 10.5km indicates that the height transfer method based on trigonometric leveling can achieve the accuracy of third-order leveling while the span is about 10km,and the rigorous reciprocal observing method can reduce the influence of astronomic refraction error obviously.
