摘　　要：为了进一步研究GPS数据处理方法,结合BERRESE5.0软件在单历元解算中的应用,阐述了精密单点动态定位(PPP)和差分动态定位处理模型和解算方法;为验证2种单历元动态定位模型的精度,提出了一套验证方案,并通过对实验数据分析验证,得出了BERNESE5.0软件2种动态数据处理模型的精度。结果表明BERNESE5.0的PPP模型和双差模型在动态数据处理中的应用可达到优于5cm的定位精度。In order to further study on GPS data processing, combining with the BERNESE5.0, the paper discussed the data-processing models and the resolution used in the dynamic single-epoch positioning and dynamic double-difference process- ing. For checking the precision of the two models, a set of verification methods was proposed. Experimental result showed that the accuracy of the two dynamic data processing models of BERNESES. 0 could be better than 5 cm.
