METHOD FOR ENHANCEMENT ACCURACY AT RF REAL-TIME LOCATING SYSTEM

摘要

PURPOSE: A method for enhancing accuracy at an RF real-time locating system is provided to reduce location errors caused by a peripheral electromagnetic interference in a changed output value in a node. CONSTITUTION: A tag(102) is in a sleep mode state during a normal time. If a tag is in a transmission period, the tag is awake. The tag receives and re-transmits the node output information and the reception sensitivity according to the received sensitivity outputted form a node. A position server(104) calculates the reception sensitivity value of the tag and the node output information received from the node. The location server detects the current position of the tag.
