Embodiments include methods and systems by which an object can be located within an area. The system includes a moveable radio frequency identification (RFID) tag reader and multiple RFID tags, which are positioned at known locations. The RFID tag reader is associated with the object, and is adapted to interrogate the RFID tags, to receive unique identifiers from responding RFID tags, to correlate the unique identifiers with tag location information stored in memory to determine fixed positions for the responding RFID tags, and to mathematically determine at least one location solution for the RFID tag reader using the fixed positions. A responding RFID tag is adapted to respond to an interrogation signal from the RFID tag reader by transmitting a unique identifier.
