摘要
目前尚未有文献对POS MV OceanMaster原始数据存储结构进行详细阐述,给后续的数据处理带来了诸多不便。从惯性导航原理入手对OceanMaster格式数据进行解析,通过软件开发对OceanMaster格式数据进行解码,提取各种数据包,并通过紧耦合算法对原始数据进行处理,分别获取三维坐标系下的位置均方差以及位置信息。实验结果表明,经过相应数据处理后可获得精度较高的位置数据,均方差约为0.03m,能够更好地为海洋测绘提供可靠的位置和姿态信息。
Due to the POS MV OceanMaster series raw data structure has not yet been published in detail in current literatures,which may bring inconvenience for subsequent data processing.This article starts with the principle of inertial navigation for OceanMaster format data parsing,and decrypts the OceanMaster format data,extracts all sorts of data packets and deals with the original data through the correct posture and Kalman filtering method,through which obtains the three-dimensional coordinates of position variance.The results show that after the corresponding data processing,the high precision position data whose mean square error is about 0.03m is obtained,and it provides reliable position and posture information for marine surveying.
