摘要
设计了一套二维深海勘探导航定位数据处理系统,主要内容包括DGPS数据和罗盘数据的粗差探测和修复、历元化算法、曲线调整和积分计算检波点坐标。利用积分模型模拟电缆的形状来计算检波点坐标,在不损失精度的前提下,简化了计算流程。
We study the navigation and positioning data processing of two-dimensional explo-ration,and design a set of navigation and positioning data processing systems.For the characteristics of two-dimensional exploration,we use the integral model to simulate the shape of the cable to calculate the detection point coordinates.Under the premise of without loss of accuracy,this method simplifies the calculation process and improves the calculating speed.The main components of this method include gross errors detection and the repair for DGPS data and compass data,data epoching,curves adjustment and detecting node calculation.Compared with some abroad mature deep-sea exploration and navigation data post-processing software,the calculation accuracy of this method meets the demand of deep-sea exploration work.
