摘要：
In order to quantitatively and accurately evaluate the positioning accuracy of integrated train positioning system (ITPS), by studying the positioning accuracy evaluation method based on the high-precision reference system, this paper proposed real-time and post-processing positioning accuracy evaluation strategies. The high-precision integrated navigation system SPAN-FSAS(Synchronized Position Attitude & Navigation-FSAS)was selected as the reference system, while instantaneous positioning error was calculated to evaluate the real-time positioning accuracy for ITPS. In addition, the positioning results based on the IE (Inertial Explorer) tightly-coupled integration and RTKLIB kinematic mode were chosen as the post-processing reference system, and multiple positioning accuracy evaluation parameters were calculated to synthetically evaluate the post-processing positioning accuracy of ITPS. The real operation data of Test Loop Track verified that the proposed method can observe the instantaneous and post-processing positioning accuracy intuitively and quantitatively for ITPS. © 2019, Department of Journal of the China Railway Society.
