PURPOSE: A precise recognition of a positioning and an intelligent searching algorithm are provide to remove environment restriction by calculating the same position data when receiving a GPS signal. CONSTITUTION: A GPS signal is received from a GPS satellite. The current position of a location detecting system is confirmed in 3D form by using the GPS signal. The GPS signal is continuously measured through a GPS signal intensity measurement and condition establishment step. Through the above step, the GPS signal is effective or not. The direction and distance of a moving terminal is calculated by using only a terrestrial magnetism sensor and an acceleration sensor of three-shaft. |
