摘要
GNSS数据预处理是实现高精度导航定位服务的重要环节。随着GNSS接收机由单频单模向多频多模发展,用户可获得的观测数据内容更为丰富,有利于增强位置服务的可靠性。针对现有GNSS数据预处理软件存在的不支持新卫星新频点数据、软件操作相对复杂和预处理功能不完善等问题,论文引入一款由日本国土地理院(GSI)研发的RINGO软件,并利用该软件进行GNSS数据预处理的实验测试和分析。实验结果表明,RINGO软件功能全面且丰富,支持数据编辑、电离层校正和质量检核等,可满足不同用户对GNSS数据预处理的需求。
GNSS data preprocessing is an important part of achieving high-precision navigation and positioning services.With the development of GNSS from single-frequency and single-mode to multifrequency and multi-mode,the observation data available to users are richer in content,which is conducive to the enhancement of the reliability of location services.The existing GNSS data preprocessing software has some problems,such as not supporting new satellite and new frequency data,relatively complicated operation and imperfect preprocessing function.This article introduces a RINGO software developed by the Geospatial Information Authority of Japan,and with which carries out experimental testing and analysis of GNSS data preprocessing.The experiment results show that RINGO software has comprehensive and rich functions,which can support data editing,ionospheric correction and quality check,etc.,and can meet the needs of different users for GNSS data preprocessing.
