METHOD FOR INCREASING RELIABILITY OF POSITION INFORMATION WHEN TRANSITIONING FROM REGIONAL, WIDE-AREA, OR GLOBAL CARRIER-PHASE DIFFERENTIAL NAVIGATION (WADGPS) TO LOCAL REAL-TIME KINEMATIC (RTK) NAVIGATION SYSTEM

摘要

FIELD: information technology. ^ SUBSTANCE: first position of the object is determined based on information from the WADGPS, and a second position of the object is determined based on position information from a local positioning/RTK positioning system; the position determined by the WADGPS and the position determined by the local positioning/RTK positioning system are then compared. The WADGPS position is used for navigating the object when the WADGPS position and local positioning/RTK position differ by more than a predefined threshold, and the local positioning/RTK position is used for navigating the object when the WADGPS position and local positioning/RTK position differ by less than the predefined threshold. ^ EFFECT: high accuracy of real-time navigation and positioning. ^ 22 cl, 7 dwg
