The invention relates to an orientation device comprising: a true north finder including a rate-gyroscope-type member, as well as sensors that can be used to measure the inclination of the device in relation to the horizontal, and associated calculation means for determining the orientation of the true north used on information provided by the rate gyroscope-type member and the sensors. According to the invention, the device also includes three feet that are used to support the device when it is placed on a support, at least one of said feet including a built-in sensor that changes state when the device is resting on a support by means of the feet, and means for automatically triggering the determination of the orientation of the north when the device is sufficiently horizontal and when the sensor indicates that it is placed on a support. |
