GPS接收机噪声及天线相位中心偏差检测技术应用

内容简介：采用“零基线检验法”对6台套LeicaGRX1200系列仪器内部噪声水平和天线相位中心偏差进行检验。使用TEQC和GAMIT／GLOBK软件进行数据处理和结果评价。文章中结合leica机器检测流程，在没有测量部门标准检定试验场的情况下，阐述如何按照规范对GPS仪器进行检验。

Abstract：Based on the Zero Baseline Method, the interior noise level and phase center variation of the six Leica GRX1200 instruments are tested. The data processing and the results' evaluation are made by using TEQC and GAMIT/GLOBK software. Combined with the testing procedure of Leica, this paper expounded how to test the GPS instrument according to the standards without standard testing ground by the measurement department.
