Influence of GPS antenna phase center model change on GPS data processing
Xiaoli Ding · Cehui kexue · 2010
GPS antenna exists phase center deviation,it must be corrected in high-precision GPS survey.There are two rnodels used in antenna phase center offset: relative phase center model and absolute phase center model.Based on the same geometrical models,the paper analyzes their difference on metrical and corrective methods and a practical example was given to research the influence of model change on GPS data processing precision,some helpful conclusions were given in the end.
