A method for controlling a vehicle includes receiving input data. The input data includes sensor data from a plurality of sensors of a vehicle. The method further includes filtering the input data with a sliding window Extended Kalman Filter (EKF) to deter...

A position output device for outputting position data indicating a current position of an object, based on position data of a determined current position of the object as determined by a satellite navigation system. When a position jump has occurred in the...

One aspect of the present invention relates to a mobile terminal having an autonomous navigation function including a map application unit configured to perform map matching of a current position of the mobile terminal onto a route from a departure point t...

Systems and methods for updating a navigation system are provided. In one implementation, a system includes: a navigation system configured to provide a navigational solution; at least one memory device configured to store a terrain object database, the te...

The method involves determining an angle of pitch and/or an angle of heading and/or an angle of roll of an aircraft (100). A first pair of accelerometers (A5, A6) used for determination of the angle of heading is arranged on a side of a center of gravity (...

A fault detection method uses inertial measurements provided by an inertial measurement unit (IMU) (2) to detect faults in position measurement equipment (PME) (4). The method uses at least one inertial measurement ( ± ( t-N ) ...± ( t )) to derive at le...

A velocity calculation device for a Personal Navigation Device (PND) includes a vertical direction acceleration detection unit (4) that is mounted on the PND, which is fixed on a mobile object, to detect the acceleration of a vertical direction generated c...

The invention is a method for compensating for coning in a strapdown inertial navigation system which utilizes groups of five successive incremental angles of rotation of a body-fixed coordinate system as measured by orthogonally-mounted gyros at regular m...

Provided are a method and apparatus for compensating for an acceleration error in an inertial navigation system (INS). The apparatus includes a motion detector that detects the motion of the INS and outputs information on stationary time intervals during w...

A vehicular navigational system (2) is provided that compensates for temperature-dependent drift of bias in a vehicle heading sensor (6) associated with a dead reckoning vehicle positioning system (12). Specifically, a Kalman filter (38) generates a calibr...
