The goal of this paper is to compare academic and online GNSS processing services for CORS-TR. To determine whether differences in the coordinate components were statistically significant, statistical significance test and 3D coordinate transformation were applied. Furthermore, local coordinates analysed to show jumps that occurred to seismic events. While there are significant differences only in the Z coordinate component between GIPSY and GAPS in the Cartesian coordinate system, all differences in local coordinate components are insignificant. 3D coordinate transformation results included random errors and there are insignificant differences in terms of transformation parameters between GIPSY and online GNSS processing services.

本文的目的是比较 CORS-TR 的学术和在线 GNSS 处理服务。为了确定坐标分量的差异是否具有统计学意义，应用了统计学显着性检验和 3D 坐标变换。此外，分析局部坐标以显示地震事件发生的跳跃。虽然在笛卡尔坐标系中 GIPSY 和 GAPS 之间仅 Z 坐标分量存在显着差异，但局部坐标分量的所有差异均不显着。3D 坐标变换结果包含随机误差，GIPSY 和在线 GNSS 处理服务在变换参数方面没有显着差异。
