Apparatus and method for efficiently providing revising information of satellite location coordinates by dynamical request of terminal

摘要

Disclosed is an apparatus and method for efficiently providing correction information of satellite position coordinates by a dynamic request of a terminal generated as the increase or decrease of the request period of the correction information is dynamically changed. An apparatus for providing correction information of satellite position coordinates by a dynamic request of a terminal includes: a threshold information management unit that generates and manages threshold information that the terminal needs to compare in order to generate a dynamic request due to the arrival of a timer period set in the terminal; In the terminal receiving the threshold information, it is determined whether the correction information is received by comparing each threshold value included in the threshold information, and receiving a dynamic request generated by the period of the increased or decreased timer according to the determined reception from the terminal A request receiving unit; And a providing unit that provides correction information and threshold information to the terminal by the received dynamic request.
