Real‐time and dynamic time transfer method based on double‐differenced real‐time kinematic mode
IET Radar, Sonar & Navigation, 2021 In this study, a real‐time and dynamic time transfer method based on double‐differenced (DD) real‐time kinematic (RTK) mode is proposed. First, the method forms the DD observations of Global Navigation Satellite System (GNSS) to fix the DD ambiguity, and
