GNSS接收机检定场设计和建造

Design and Construction of GNSS Receiver Verification Field

为满足全球导航卫星系统(GNSS)接收机等高科技测绘仪器检定以及常规测绘仪器长度的检定,潍坊市计量测试所建立GNSS接收机检定场。本文对GNSS接收机检定场的设计和建造进行了描述,给出了GNSS接收机检定场设计原则,依据要求对场地选址、超短基线场、短基线场、中长基线场、动态检定场进行了探讨,并描述了GNSS接收机检定场观测墩埋设规格和要求,以及GNSS接收机检定场设计达到的最终技术指标等。同时介绍了GNSS接收机检定场建造过程中为保证达到设计要求所运用的方法和技术,对设计和建造GNSS接收机检定场具有参考意义。

In order to meet the requirements of the verification of high-tech surveying and mapping instruments such as GNSS receivers and the length verification of conventional surveying and mapping instruments, GNSS receiver verification field established in Weifang Institute of Metrology & Testing. The paper describes the design and construction of GNSS receiver verification field. The design principle of GNSS receiver verification field is given. According to the requirements, the site selection, ultra short baseline field, short baseline field, medium long baseline field and dynamic verification field are discussed. The specifications and requirements of the observation pier embedded in GNSS receiver verification field are described. As well as GNSS receiver verification field design to achieve the final technical indicators. At the same time, the paper introduces the methods and techniques used in the construction process of GNSS receiver verification field to ensure that the design requirements are met. It has reference significance for designing and building GNSS receiver calibration field.
