Beschreibung
Zusammenfassung:	A hybridized system for measuring the attitude of a wearer, the system includes a satellite positioning system; a measurement unit comprising at least one gyrometer; electronics for calculating the attitude information of the wearer from the information originating from the satellite positioning system and the measurement unit. The hybrid system comprises calculation electronics comprising a means for calculating an angular radius of protection, that is to say an angular radius such that the risk that the error between the calculated attitude and the true attitude of the wearer is not included within this radius is less than a given probability, the radius being equal to the sum of two contributions, the first contribution being equal to positioning errors linked to the measurement unit, the second contribution being equal to positioning errors linked to the satellite positioning system.
