摘　　要：手持GPS接收机的校准是检验此类产品是否达标的重要工作,在实际应用中经常遇到。针对手持机测量大地高精度偏低的问题,该文在传统理论的基础上,提出了"大地高取代法""实测拟合法"和"特定校准法"三种手持机校准方法。通过实测案例论证了所提方法的有效性,经对比分析,推荐使用更全面的"实测拟合法"进行校准工作,以保障手持GPS接收机校准结果的客观准确性。该文对于手持GPS接收机的实际校准工作具有一定的参考价值。Calibration of hand-held GPS receiver is often encountered in the actual application, which is the key of checking whether these products are up to standard or not. Aiming at hand-held GPS receiver＇s poor height surveying accuracy, this paper presented some new calibration methods like elevation replacing method, measurement fitting method and specific calibration method. This paper also verified the feasibility of the new method by measurement, it recommended using measurement fitting method to calibrate receiv- ers. This paper has actual reference value for calibration.
