| 摘 要： | 针对GNSS数据处理中框架点的选取,以及GNSS数据处理与全球解绑定和相似变换参数的选取问题,设计4种计算方案,分析了各种尺度GNSS观测网下不同计算方案得到的时序位移差异.结果显示:对于各级GNSS网,在与全球H文件联合解算并满足相同相似变换要求的前提下,选择IGS05的全部框架点和从中较均匀地挑选部分框架点得到的结...

| Abstract: | Aiming at selection of frame sites,combination of global H-files and selection of parameters of similarity transformation,four calculation schemes are designed to process the observations of regional GNSS net in large,medium and small scale.On the basis of these solutions,the differences shown as follows between results under different calculation schemes are analyzed.As far as all levels of regional net are concerned,if combined with global H-files and similarity transformation is invoked successfully,the ... |
