Research on Integer Ambiguity Algorithm of GNSS under Different Monitoring Modes

Abstract

According to the different requirements of GNSS deformation monitoring in terms of time and accuracy, based on the traditional periodic repeated monitoring mode, two GNSS monitoring modes, fixed continuous monitoring mode and real-time dynamic monitoring mode, are adopted, and the corresponding double difference integer ambiguity processing algorithm is mainly studied, so as to form a GNSS model to meet the monitoring requirements of different accuracy levels and time resolution, and through the analysis of examples to verify the correctness of the two methods.
