In this paper, the GNSS single epoch algorithm is used to measure the dynamic dynamic deformation of the high-rise building. The mathematical model of the deformation information of the single epoch is studied, the single epoch algorithm of no whole week parameter and single epoch similar single difference algorithm model is analyzed to determine the error source of the single epoch similar single difference algorithm model in GNSS deformation monitoring. In order to improve the accuracy of GNSS dynamic monitoring and measurement, this paper simulates and systematically studies the GNSS single epoch algorithm to provide guidance for the deformation law and healthy operation of the building.
