Abstract
An electromagnetic position and orientation detector. A determination is made by a calculator of the position and the orientation of a mobile sensor as a function of the coupling coefficients measured between each of the coils of the sensor and each of the coils of a transmitter. These measurements are tainted with errors due to the imperfections in gain of the various elements of the transmission and reception channels. To eliminate these errors, a stationary sensor is used whose coupling coefficients with the coils of the transmitter are measured to serve as a reference to correct the coupling coefficients between the coils of the transmitter and of the mobile sensor.
