【摘要】 系统时差目前一般只能在时间实验室采用标校过的GNSS接收机进行获取。论文首次提出了一种新的单站时差监测方法,基于该方法设备时延不需要进行标校,而是得到了消除。文章的第一部分总结、分析了目前GNSS时差监测主要的方法;文章的第二部分详细阐述了本文提出的新方法;文章第三部分介绍了单站多卫星系统时差监测数据处理的流程;文章最后给出了单站多卫星系统时差监测的结果,并与其它方法求得的结果进行了比较验证。更多还原

【Abstract】 To derive the timing bias, i.e. time offset between different satellite systems, hardware delay has to be measured. The GNSS receiver calibration is a complicated and environment demanding task, which is normally not performed for geodetic GNSS receivers. To overcome this problem, we present a new method for timing bias estimation at single station. Instead of calibrating, the hardware delay of the receiver at cancelled out in our approach. The first part of the paper reviews approaches for GNSS time bias estimation. In the second part, we introduce the new approach in detail. The last part of the paper describes software system developed and shows recent results.更多还原
