In the year 2009, a new system called IMC (Integrated Magnetic Compass) was developed by researchers at the University of the Basque Country. This new compass obtains, in real time, all the deviations at all the compass courses that the vessel steers. In other words, it calculates all the deviations and can print a deviation card with the latest deviations of the compass. Patents have been obtained for this invention both by the University of the Basque Country and by another American patent, and a PhD dissertation has been completed on this new system. This paper begins by introducing a simplified compensation system, which the authors are developing based on the proposals put forward in the dissertation mentioned above, and using the data provided by the IMC. This new device will allow us to substitute the old compensation system based in standard spheres, magnetic bars, heel magnets and Flinder’s bar, by a simple adjustable disc with magnets bars. The aim is to define how to use it, and to be able to compensate properly the deviations at any moment with minimum knowledge.
