SYSTEM AND METHOD FOR LOCATION TRACKING

摘要

A system for position tracking according to the present invention comprises: at least one position identifying terminal which generates position data based on received GPS signals, and generates and transmits beacon signals which include the generated position data and an identified ID; and at least one fixed position coordinate sensor node where the installed fixed position coordinates are stored, which calculates the separation distance from a position identifying terminal based on the signal intensity of the received beacon signals, and estimates the position coordinates of the position identifying terminal based on the received position data, calculated separation distance, and stored fixed position coordinates.
