Determination of positions

摘要

A method for position determination, having a first step, in which a first sequence of positions is determined from radio signals of stationary transmitters, and a second sequence of positions being determined from other sensor data by dead reckoning. The first sequence of positions and the second sequence of positions are compared with one another in a second step. A computer program product for carrying out the method is also provided. A position determining device, in particular in a mobile terminal is also provided, having a receiver for radio signals of stationary transmitters, having position determining means for determining a first position of the receiver from radio signals of stationary transmitters, sensors at least for determining a direction and a distance in order to determine a second position by dead reckoning, and a memory for storing a sequence of first positions and a sequence of second positions. The first position determining device has a processing unit for comparing the sequence of first positions and the sequence of second positions.

1. A method for position determination, comprising:
obtaining, by processing circuitry and via a receiver, electronic radio signals from stationary transmitters; obtaining, by the processing circuitry and via an input interface, sensor data from at least one sensor; determining, by the processing circuitry, a first sequence of positions by processing the electronic radio signals from the stationary transmitters; determining, by the processing circuitry, a second sequence of positions by dead reckoning processing of the sensor data; comparing, by the processing circuitry, the determined first sequence of positions to the determined second sequence of positions; ascertaining position information, by the processing circuitry and based on the comparison, wherein the position information is a resulting sequence of positions that represents a deviation of the first and second sequences of positions from each other; and optimizing the first sequence of positions by: differentiating the determined first sequence of positions; and weighting the differentiated determined positions based on the resulting sequence of positions to correct the deviation.
