Real‐time and dynamic time transfer method based on double‐differenced real‐time kinematic mode

In this study, a real-time and dynamic time transfer method based on double-differenced (DD) kinematic (RTK) mode is proposed. First, the forms DD observations of Global Navigation Satellite System (GNSS) to fix ambiguity, then, all fixed single-differenced (SD) ambiguities are recovered while defining SD ambiguity datum; finally, uses realise by using ambiguities. Five different baseline links were used for validations. The results demonstrated that DD-RTK can be both positioning precise transfers, it provides much better accuracy stability than un-differenced point because operated broadcast ephemeris, which more convenient applications.
