The existing GNSS deformation monitoring systems often adopt the single-baseline solution (SBS) model due to its simplicity and ease of implementation. When monitoring long-span linear objects such as bridges and railways, or large-area land subsidence, multiple reference stations are often used. However, the SBS model neglects the mathematical correlation between baselines, and sometimes the accuracy and reliability can be limited due to long baseline length and satellite occlusion. This paper proposes to use the multi-baseline solution (MBS) model to solve the deformation monitoring network. Based on real monitoring datasets, the accuracy of MBS model and SBS model were compared. The experimental results show that, compared with SBS, MBS can improve the ambiguity fixing rate and the coordinate accuracy by up to 22.7% and 27.8% respectively.
