摘要
如何将GPS位置实时推算至海底地形点位置、获取海底测点在地理坐标系中的精确位置是一个十分复杂的计算过程。文章从数学角度剖析了这一坐标转换的全部过程,揭示了多波束水深点定位的实质,指出了各步转换中的具体转换参数实际内涵。以便对多波束的实现理论更加清楚,对于控制误差传播、测量关键环节的质量控制都有十分重要的意义。
It is acomplicated procedure that how to transfer the location of GPS to accurate survey point on sea-bed in geographic coordinate system.This paper analyses the whole procedures by mathematic principal,reveals the essence of multi-beam positioning on sea-bed point and points out the real content of transformation parameter,which can help us to recognize the multi-beam positioning principle better.It is significant to control error propagation and grasp the key link in quality control.
