长度基线校准装置的设计与实现

为了实现长度基线的量值统一,保证长度基线的溯源和量传准确,在分析长度基线校准方式、测量标准的建立、溯源途径和计量保障需求的基础上,采用高精度光电测距仪和GPS接收机建立了长度基线校准装置测量标准,解决了传统基线校准方法难于实现大长度、空中基线的校准问题,提高了长度基线校准精度、效率,降低了生产成本,丰富了长度计量标准器具。

Design and Implementation of Calibration Device for Length of Field Baseline

In order to ensure the accurate value and realize the value unification for the length of field baseline,we research the establishment of the standard equipment,the way of tracing to the source and the requirement of field metrology support.Base on this,the paper studies the performance of three instruments such as ME5000 EDM instrument,TC2003 total station and R7 GPS receiver,and analyzes the uncertainty of measurement.By using the calibration device for the length of field baseline,the labor intensity and cost will be reduced, and work efficiency will be improved.
