Abstract

AbstractIn the paper, the differences between position components obtained using the precise point positioning (PPP) technique with individual and type mean PCC models were investigated. Daily GNSS observations from ten selected European Permanent Network (EPN) stations were used in the study. Eight different combinations of GPS, Galileo, BeiDou and GLONASS systems observations were proposed for analyses. The observation processing was done using the open-source software package GAMP. The results show that differences in the calibration models propagate to the position domain. Position offsets, resulting from the use of individual calibrations instead of the type mean, reach up to 10 mm in the vertical component while are generally keeping below 2 mm in the horizontal ones. The analysis also shows that adapting GPS PCCs to other GNSS (e.g. Galileo or BeiDou) signals does not significantly increase achieved position component differences.Keywords: multi-GNSSEPNantenna phase center correctionsposition components time series‌PPP AcknowledgmentThe author is grateful for GNSS data provided by the International GNSS Service, EUREF Permanent Network, and Zhou et al.

在多gnss PPP中使用类型平均值与单个接收天线PCC的影响

摘要本文研究了精确点定位(PPP)技术在个体和类型平均PCC模型下得到的位置分量的差异。研究中使用了10个选定的欧洲永久网络(EPN)站的每日GNSS观测数据。提出了GPS、伽利略、北斗和GLONASS系统观测的8种不同组合进行分析。使用开源软件包GAMP进行观测处理。结果表明，标定模型的差异会传播到位置域。由于使用个别校准而非型号平均值，垂直组件的位置偏移可达10毫米，而水平组件的位置偏移通常保持在2毫米以下。分析还表明，将GPS PCCs与其他GNSS(例如伽利略或北斗)信号相适应不会显著增加所获得的位置分量差异。关键字:多gnssep纳米天线相位中心校正位置分量时间序列PPP致谢感谢国际GNSS服务、EUREF永久网络和Zhou等人(Citation2018)提供的GNSS数据免费共享GAMP软件。披露声明作者未报告潜在的利益冲突。karol Dawidowicz karol Dawidowicz于2001年在奥尔什丁的瓦姆尼亚和马祖里大学获得卫星大地测量学博士学位。主要研究方向为GNSS调平、GNSS天线相位中心变化建模和精密点定位。他是全球导航卫星系统数据处理高级方法组的成员。Mieczysław BakułaMieczysław Bakuła于1999年获得卫星大地测量学博士学位。他的研究主要集中在全球导航卫星系统的定位及其在测量和导航中的应用。他是精确和快速的歧义解决/重新初始化方法(PREFMAR)的作者。

期刊介绍： Survey Review is an international journal that has been published since 1931, until recently under the auspices of the Commonwealth Association of Surveying and Land Economy (CASLE). The journal is now published for Survey Review Ltd and brings together research, theory and practice of positioning and measurement, engineering surveying, cadastre and land management, and spatial information management. All papers are peer reviewed and are drawn from an international community, including government, private industry and academia. Survey Review is invaluable to practitioners, academics, researchers and students who are anxious to maintain their currency of knowledge in a rapidly developing field.
