POSITION LOCATION SYSTEM |
摘要 |
Methods and apparatus are provided for locating the position, preferably in three dimensions, of a sensor by generating magnetic fields which are detect ed at the sensor. The magnetic fields are generated from a plurality of locations and, in one embodiment of the invention, enable both the orientation and location of a single coil sensor to be determined. The present invention thus finds application in man y areas where the use of prior art sensors comprising two or more mutually perpendicular coils is inappropriate.
