GNSS RTK接收机检定的国际标准ISO 17123-8及其实验结果分析

International standard ISO 17123-8 and its application in verifying GNSS RTK receiver

针对国内同行对GNSS RTK接收机检定的国际标准ISO 17123-8不悉知的情况,以ISO 17123-8最新版为蓝本,介绍了国际标准ISO 17123-8检定GNSS RTK接收机的方法,详细阐述了简化检定及完整检定的全过程。以海星达H32接收机为例,对该仪器进行了实际检定。其结果表明:受检仪器的技术指标满足出厂要求,与仪器的计量检定结论一致。同时,该方法可以用于核查在计量检定周期内,GNSS RTK接收机是否处于正常的工作状态,精度能否达到出厂指标,这样能够确保测量成果可靠。

For solving the professional problem of unknowing about the national standard ISO 17123-8 for verifying GNSS RTK receiver,according to the newest ISO 17123-8 version,the field of verification and the method of data acquisition and process,which are stipulated by the national standard ISO 17123-8,are introduced.The result of a verification example indicates that the technical indexes of the verified instrument meet the factory requirements,which is in agreement with the conclusion of its metrological verification.So,in a period of metrological verification,the normality and precision of GNSS RTK receiver can be checked by the national standard ISO 17123-8.
