摘要
A mobile device is described. The mobile device includes an electronic compass that generates compass data corresponding to an orientation of the mobile device relative to true north. A global positioning system (GPS) module receives a GPS signal from multiple satellites. The GPS module determines a heading direction of a vehicle transporting the mobile device relative to true north based on the position data when the vehicle is moving above a threshold velocity. A motion sensor generates motion data corresponding to a motion of the mobile device when the mobile device is moved. A processor adjusts the heading direction of the vehicle relative to true north based on the compass data when the vehicle is moving below the threshold velocity.
