GBAS Apparatus and Method for correcting vector error to extend operational boundary of Ground Based Augmentation System

摘要

According to an embodiment of the present invention, there is provided a vector error correction apparatus for extending a GBAS operation range, comprising: a satellite; A ground based augmentation system (GBAS) base station for receiving position information from the satellite and generating and transmitting vector-type correction information for correcting a position error according to spatial spacing error; And a user terminal for calculating a current position using the transmitted vector type correction information. According to the present invention, horizontal or vertical spatial spacing error can be minimized by dividing the error component integrated into one scalar correction information of the zone and transmitting it as vector correction information to the user.
