High-Precision Dynamic Deformation Monitoring Model of GPS/Pseudolites Integrated System

Aiming at the characteristics of small deformation range and strong correlation of multipath errors in space, a high-precision dynamic deformation monitoring model of GPS/pseudolites integrated system is proposed by introducing time forgetting factor. The model can effectively eliminate the influence of multipath of Pseudolite on combined positioning and improve the positioning accuracy and reliability in theory. The findings of the research have led the author to the conclusion that high-precision integration of GPS/pseudolites dynamic deformation monitoring model can weaken the influence of pseudolites multipath on integrated positioning more efficiently than conventional model, which increases the positioning precision largely.
