0引言数据处理的流程包括数据采集、数据预处理、解算等。数据采集是接收机记录原始观测数据。数据预处理阶段的主要工作包括数据传输和解码、数据筛选和编辑、数据标准化、接收机钟差估算、差分观测值或线性组合观测值形成、基线向量近似值估算和周跳探测、修复或标记等。数据解算指对采集到的观测值进行处理,最终输出相应的结果。在数据筛选和编辑过程中,将根据观测值的信噪比、卫星高度角、卫星健康状态、观测值间的同步情况等对数据进行整理, 0 Introduction Data processing processes include data acquisition, data preprocessing, solution and so on. Data acquisition is the receiver to record the original observation data. Data preprocessing stages include data transmission and decoding, data filtering and editing, data normalization, receiver clock error estimation, formation of differential observations or linear combination observations, estimation of baseline vectors and hopping, repair or labeling, etc. . Data solution refers to the observation of the collected data processing, the final output of the corresponding results. During data screening and editing, the data will be sorted according to the signal-noise ratio of the observed value, the altitude of the satellite, the state of satellite health, and the synchronization between observations.
