This method and device provides, on the one hand, for determining the vehicle course, that the data be acquired from a number (for example three) of gyro compasses with different stochastic error characteristic but at least partially compensating for one another, in order to determine individual errors, that the data be supplied to an arithmetic averaging circuit and a trip error correction be carried out. To determine the lateral bearing of the object, on the other hand, one or a number of bearing diopters are used, the angle of which between their optical axis and the longitudinal axis of the ship is picked up via an angle encoder and output for further processing to a course and direction-finding computer, the validity of the bearing value being marked by an observer by triggering an electrical signal. Vehicle course and bearing are then combined in a course and direction-finding computer for determining the true bearing.

System and method for enhancing non-inertial tracking system with inertial constraints

A position and orientation of a device 100 is found by estimating a first tracking state of the device using measurements from an exteroceptive sensor (ES) 104 such as a camera, sampled at a first rate.

METHOD FOR POSITION AND LOCATION DETECTION BY MEANS OF VIRTUAL REFERENCE IMAGES

A method describes the architecture of a vision-supported navigation system in a terrain using available topographical maps, which is based on already existing methods for detecting prominent terrain features. An offline process used in this case creates a feature database from existing topographical maps, which is subsequently used in an online process for recognising features that have been seen. In this case, virtual reference images of the expected situation are created using computer graphical methods, which are analysed using methods for feature extraction, and a feature catalogue made up of vision-based feature vectors and the associated 3D coordinates of the localised features is derived from the same. These data are stored in a flight system in the form of a model database, for example, and enable navigation close to a reference trajectory and for a planned lighting situation. High localisation characteristics and a correspondingly high navigation accuracy are achieved by means ...
