文中就多系统GNSS数据质量检测及预处理的算法展开研究,基于MATLAB软件平台自行开发了GNSS-QL软件,可实现对美国GPS和中国北斗两大GNSS系统的数据质量检测及预处理,该软件具有操作简便、精确度高等特点,为GNSS系统进一步应用于相关领域奠定基础。

Welcome to GNSS-SDR! This program is a software-defined receiver which is able to process (that is, to perform detection, synchronization, demodulation and decoding of the navigation message, computation of observables and, finally, computation of position fixes) the following Global Navigation Satellite System's signals: In the L1 band: artificial_satellite GLONASS L1 C/A (centered at 1602.00 MHz) white_check_mark artificial_satellite GPS L1 C/A (centered at 1575.42 MHz) white_check_mark artificial_satellite Galileo E1b/c (centered at 1575.42 MHz) white_check_mark artificial_satellite BeiDou B1I (centered at 1561.098 MHz) white_check_mark In the L2 band: artificial_satellite BeiDou B3I (centered at 1268.520 MHz) white_check_mark artificial_satellite GLONASS L2 C/A (centered at 1246.00 MHz) white_check_mark artificial_satellite GPS L2C (centered at 1227.60 MHz) white_check_mark In the L5 band: artificial_satellite GPS L5 (centered at 1176.45 MHz) white_check_mark artificial_satellite Galileo E5a (centered at 1176.45 MHz) white_check_mark GNSS-SDR provides interfaces for a wide range of radio frequency front-ends and raw sample file formats, generates processing outputs in standard formats, allows for the full inspection of the whole signal processing chain, and offers a framework for the development of new features.
