| Abstract: | 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. |
