Abstract: 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.
