Abstract

The article presents a prototype wearable device that corrects inaccurate GPS readouts during pedestrian travel. The electronic circuit consists of a microcontroller, an accelerometer and a digital compass. The accelerometer readouts are filtered to detect the steps of the pedestrian and are also used to estimate the stride length. The digital compass provides the direction of motion. When the GPS parameters warn of a high dilution of precision, the location of the pedestrian is corrected by data provided by the accelerometer and the digital compass.
