METHOD OF GENERATING, TRANSMTTING AND RECEIVING CORRECTION INFORMATION FOR REAL TIME KINEMATIC-GLOBAL POSITIONING SYSTEM

摘要

PURPOSE: A correction information generating, transmitting and receiving method for a satellite navigation accurate real-time kinematic(RTK) and an apparatus for the same are provided to increase the endurance for the data communication time delay of the RTK-GPS correction data as well as to minimize the additional RTK-GPS accuracy position error due to the data time delay. CONSTITUTION: A correction information generating, transmitting and receiving method for a satellite navigation accurate real-time kinematic(RTK) includes the steps of: a first step of extracting various GPS navigation data from GPS receivers(10,21); a second step of calculating the distance and satellite time error from the GPS reference station to various GPS satellite; a third step of estimating the GPS time error of the GPS receivers(10,21) of the GPS reference station by using the various GPS data; a fourth step of generating RTK-GPS correction information through the various GPS data; a fifth step of transmitting the RTK-GPS correction data; a sixth step of compensating the data communication time delay error; and a seventh step of reconstructing the GPS quasi distance measurement value and the carrier wave phase correction value of the GPS reference station from the RTK-GPS correction data.
