摘要： Optoelectronic measuring device having an electronic magnetic compass and a compensation device assigned to the magnetic compass for compensating device-fixed interference fields and is designed to occupy at least two defined, repeatable operating states and generates a different device-fixed interference field in each of the operating states. The measuring device is designed to occupy at least two defined, repeatable application states, the magnetic compass being exposed to a different external magnetic interference field in each of the application states. The compensation device being designed to measure a first, second and third magnetic field set in a first, second and third overall state of the measuring device, and to determine by means of the processing unit a first, second and third set of parameters based on the first, second and third magnetic field set respectively, and to derive a fourth parameter set based on the first, second and third parameter set.

摘要： Disclosed is an optoelectronic measuring device having an electronic magnetic compass for determining an azimuthal alignment of the measuring device and a compensation unit, which is associated with the magnetic compass, for compensating for device-fixed interference fields, wherein the measuring device assumes at least two defined, repeatable operating states, has a different device-fixed interference field in each of the operating states, and the compensation unit carries out an initial compensation of the electronic magnetic compass in a first operating state of the measuring device, wherein the compensation unit has a detection unit for detecting a present operating state, a memory unit for storing a magnetic offset resulting from the different device-fixed interference fields between the first and a second operating state of the measuring device, and a computer unit for computing the azimuthal alignment of the measuring device depending on an ascertained operating state and based on the magnetic offset.

摘要： A north-referenceable goniometer for azimuthal orientation determination of a sighting device has a base, a rotary part, a rotation angle encoder for determining a rotational position of the rotary part about an upright axis, a gyroscope fixed on the rotary part and having a measuring device oriented orthogonally to the upright axis for determining a component of the Earth rotation vector, and an evaluation unit for determining the azimuthal angle of the geographical north pole. The goniometer also includes an acceleration sensor, and the evaluation unit is formed such that, using the evaluation unit, the determined component of the Earth rotation vector is corrected by a sink rate of the goniometer, determined with the aid of the acceleration sensor, and a systematic measurement error of the gyroscope is corrected by determining measurement values of the component of the Earth rotation vector in at least three different rotational positions.

摘要： The invention relates to a method for a field compensation of an electronic compass for influences to a geomagnetic field by magnetic objects in the vicinity of the compass, that is done with acquiring a magnetic field value by a magnetic field sensor and acquiring an inclination with respect to level plane by an accelerometer, in a discrete set of multiple orientations of the compass.Therein, a user guidance for subsequently orienting the compass into a predetermined desired range of orientation is provided to the user. In the following, compensation data are calculated from those magnetic sensor acquisitions to compensate for the influences in such a way, that a magnetic north heading is determinable based on the compensated magnetic field values.Therein, the user guidance for the compensation is done with a gathering of directional information based on rotary rate readings from a gyroscope for an azimuthal component of the orientation.
