摘要
An integrated position and direction system is disclosed that includes a digital compass and a satellite positioning system (SATPOS) having a receiver adapted to receive satellite position determining signals. Direction is determined using the digital compass and heading is determined using the SATPOS. The integrated position and direction system is operable to display, on a display device, map information that is oriented according to a current orientation regardless of whether the system is stationary or moving. The map display is oriented according to either heading determined using the satellite positioning system or direction determined using the digital compass. The integrated position and direction system updates the map display to orient the map display with a current position. Moreover, the integrated position and direction system updates the map display to orient the map display with a current orientation (e.g., heading or direction).
