摘　　要：在5G+北斗的新基建时代,基于GNSS卫星服务与INS惯性导航的融合定位技术,成为智能驾驶的标配。近年来伴随着北斗第三代卫星导航系统和地基增强系统的陆续建成,如何高效地利用这些资源并在智能驾驶领域应用落地已经成为智能汽车行业研究的重点。基于此,文章依托中国移动的高精度定位服务,针对集成了上海司南高精度RTK定位算法的TBOX进行路测,以判断其定位性能。测试表明,该TBOX能很好地满足一般智能驾驶对高精度定位服务的需求。In the new infrastructure era of 5G+ Beidou, the integrated positioning technology based on GNSS satellite service and INS inertial navigation has become the standard of intelligent driving. In recent years, with the completion of beidou thirdgeneration satellite navigation system and ground-based enhancement system, how to efficiently utilize these resources and apply them in the field of intelligent driving has become the focus of intelligent vehicle industry research. Based on this, this paper relies on the high-precision positioning service of China Mobile and carries out road test for TBOX integrated with Shanghai Sinan high-precision RTK positioning algorithm to judge its positioning performance. The test results show that the TBOX can well meet the requirements of general intelligent driving for high-precision positioning services.
