摘要

尽管研究人员广泛研究了全球导航卫星系统定位误差源的分析和建模，但其中一些误差并没有被显著消除，只有全球导航卫星系的一些数据被建模。目前的工作是为了确定不同变量的影响，即：季节、可见卫星数量和精度稀释对水平和垂直CORS（连续运行参考站）定位效率的影响。为此，在600个时期内，以1秒的间隔在14个不同的测试点收集CORS数据。因子设计提供了一个有效的解决方案来理解几个因素对响应变量的影响。为了达到这些目的，采用了在两个水平上具有三个因素的全因子设计。根据全因子设计的结果，所有因素都显著影响反应变量。分析了各因素对CORS水平和垂直定位的影响。得到了所有情况下的回归方程。

A Modelling Study by Factorial Design on GNSS Positioning

Although researchers have widely studied the analysis and modelling of error sources on Global Navigation Satellite Systems positioning, some of these errors have not been eliminated significantly and only some of the Global Navigation Satellite System’s data are modelled. The present work was undertaken to determine the effect of different variables, namely: season, the number of visible satellites, and dilution of precision on the efficiency of horizontal and vertical CORS (Continuously Operating Reference Stations) positioning. For this aim, the CORS data was collected at 14 different test points during 600 epochs with 1-second intervals. Factorial designs supply an efficient solution to understand the impact of several factors on a response variable. A full factorial design with three factors at two levels was applied for these purposes. According to the results of the full factorial design, all factors significantly affected the response variable. Also, the interaction effects of factors were analysed on the CORS horizontal and vertical positioning. The regression equations were obtained for all situations.
