近年来,随着多系统全球导航卫星系统(global navigation satellite system,GNSS)的迅速发展以及实时高精度应用需求的日益增长,国际GNSS服务分析中心(International GNSS Service,IGS)提供的状态空间表述(state space representation,SSR)产品越来越丰富。评估不同分析中心的GNSS实时产品及其定位性能对用户具有重要参考价值。对中国科学院(Chinese Academy of Sciences,CAS)、法国太空研究中心(Centre National d’Etudes Spatiales,CNE)、德国宇航中心(Deutsches Zentrum für Luft-und Raumfahrt,DLR)、西班牙航天与防务公司(GMV Aerospace and Defense,GMV)、德国地学研究中心(Deutsches GeoForschungsZentrum,GFZ)、武汉大学(Wuhan University,WHU)6个分析中心的GPS/北斗卫星导航系统(BeiDou satellite navigation system,BDS)SSR产品的可用性、精度和实时精密单点定位性能进行了评估。实验结果表明:CAS播发的GPS卫星可用性最高,提供了所有32颗GPS卫星的SSR改正数;CAS、GFZ、WHU 3家分析中心的BDS卫星可用性相对较高,提供了15(BDS-2)+27 (BDS-3)卫星的SSR改正数。在6个分析中心中,WHU的GPS卫星的三维轨道精度和钟差精度均为最佳;不同分析中心GPS卫星的信号空间测距误差(signal-in-space ranging errors,SISRE)普遍优于5 cm,不同分析中心GPS卫星的SISRE值的大小顺序为:WHU < GMV < CNE < DLR < GFZ < CAS;BDS卫星轨道钟差精度相对较差,表现最优的WHU分析中心的BDS-2和BDS-3的中地球轨道卫星精密产品的SISRE值分别为8.83、5.91 cm。在单GPS动态PPP模式下,DLR的收敛速度最慢,GFZ收敛速度最快;加入BDS卫星以后,定位精度无显著差异,但能够有效提升收敛速度。
Objectives
2
In recent years
the rapid development of multi-system global navigation satellite systems (GNSS) and the growing demand for real-time
high-precision applications have led to an increasing variety of state space representation (SSR) products provided by the International GNSS Service (IGS). Evaluating the accuracy and availability of GNSS real-time precise products and their positioning performance across different analysis centers is of great importance for users. We aim to assess the availability and accuracy of real-time SSR products and their impact on real-time precise point positioning (PPP) from six commonly used analysis centers.
Methods
2
We evaluated the epoch availability and satellite availability of SSR corrections
as well as the accuracy of GPS and BeiDou satellite navigation system (BDS) precise orbit and clock products. Simulated kinematic GPS and GPS/BDS PPP experiments were conducted to investigate the relationship between SSR product accuracy and three-dimensional (3D) position accuracy.
Results
2
The Chinese Academy of Sciences (CAS) exhibited the highest availability for GPS satellites
providing SSR corrections for all 32 GPS satellites. CAS
Deutsches GeoForschungsZentrum (GFZ)
and Wuhan University (WHU) demonstrated the highest availability for BDS satellites
with all three providing SSR corrections for all 15 BDS-2 and 27 BDS-3 satellites
excluding BDS-3 geostationary Earth orbit (GEO) satellites. Among the SSR products from the six analysis centers
WHU's GPS satellites achieved the best 3D orbit and clock accuracy. The signal-in-space ranging errors (SISRE) for GPS satellites across all six centers were generally better than 5 cm. The SISRE ranking for GPS satellites was as follows: WHU < GMV Aerospace and Defense (GMV) < Centre National d’Études Spatiales (CNE) < Deutsches Zentrum für Luft- und Raumfahrt (DLR) < GFZ < CAS. In contrast
the orbit and clock accuracy of BDS satellites was comparatively lower. For WHU
the best-performing analysis center
SISRE values for medium Earth orbit satellites of BDS-2 and BDS-3 were 8.83 cm and 5.91 cm
respectively. In GPS-only kinematic PPP
DLR exhibited the slowest convergence speed
while GFZ achieved the fastest. Adding BDS satellites did not significantly improve positioning accuracy but effectively enhanced convergence speed.
Conclusions
2
SISRE is shown to reliably reflect the 3D position accuracy of GPS-only kinematic PPP. Moreover
incorporating BDS satellites can significantly improve convergence speed
even if their impact on positioning accuracy is minimal.
