摘　　要：主要是利用了Matlab二次开发编制了teqcplot部分程序模块,实现了对teqc的图形显示和可视化查询,使质量检查结果更加清晰明确,同时将GPS观测数据中的多路径效应和信噪比的影响定量地显示出来,提高了数据的有效处理。用某次北极科考的实测数据进行有效性验算,并根据检查的结果对GPS的观测数据进行相应的处理,结果表明,经过TEQC预处理后的数据质量结果均符合检测经验值,在GPS基线解算的质量方面得到了有效的提高。This paper mainly use the Matlab teqcplot part is compiled secondary development module,so as to realize the graphic display and visualization query of teqc,make quality inspection results more clear,will further the multipath effects of GPS observation data and displayed quantitatively the influence of signal-to-noise ratio,thus to further improve the effective data processing.And use the measured data of an arctic expedition for effective analysis,and according to the result of checking of GPS observation data to carry on the corresponding processing,compares and discusses the processing result shows that after TEQC pretreatment of data quality results conform to the inspection experience value,thus in the quality of the GPS baseline solution has been effectively improved.
