摘　　要：广西南宁全球导航卫星系统(GNSS)接收机检定基线场建于2001—2003年,于2018年完成升级改造,是全国唯一有高铁穿过的GNSS接收机检定基线场。该检定场分为中长基线场、短基线场和超短基线场,其中,中长基线和短基线检定场均建设8个观测墩,超短基线场建设7个观测墩。本文通过梳理该检定场过去十年基线长度成果数据,获取每次的数值及精度变化情况,分析改造前后的数据情况,判断广西南宁GNSS接收机检定基线场的可靠性和稳定性。The baseline field for global navigation satellite system(GNSS)receiver calibration in Nanning City,Guangxi Province was built from 2001 to 2003 and upgraded in 2018.It is the only GNSS receiver calibration field passed by high-speed rail in China.The calibration field is divided into medium-long baseline field,short baseline field and ultra-short baseline field,among which eight observation piers are built in the medium-long baseline and short baseline fields,and seven observation piers are built in the ultra-short baseline field.The reliability and stability of the calibration baseline field of GNSS receiver in Nanning City,Guangxi Province are judged in this paper by combing the baseline length data of the mentioned field in the past ten years,obtaining the changes of length and accuracy each time,and analyzing the data before and after the renovation.
