GPS数据联合处理中天线自定义问题

Self-defined antenna in GPS data joint processing

为了研究GPS数据联合处理,采用自定义和工程实际相结合的方法,在对GPS天线的几何相位中心、电学相位中心、物理相位中心和标志相位中心及其相互关系进行阐述的基础上,根据TGO软件中天线定义格式定义了Leica AT502天线。用工程实际数据证明所提出自定义天线方法的完整性、准确性和可靠性。为GPS数据的联合处理提供了理论依据,具有实际应用价值。

In terms of GPS data joint processing,this study investigates Geometric Phase Center,the Electric Phase Center,Physical Phase Center,Nominal Phase Center in GPS antenna and their relationships.Based on the antenna form in TGO software,LEICA AT502 antenna is defined.The engineering practice proves that the technique developed for user-defined antenna is complete,accurate and reliable.The technique provides a theoretical basis and practical mean in GPS data joint processing.
