GPS Compass: A Novel Navigation Equipment

Abstract:	A GPS (Global Positioning System)-based compass is designed, which consists of three parts: the pointer, the sensor, and the controller. Using the carrier phase signals from GPS satellites, the I-m long pointer equipped with two GPS receivers can point to the desired direction with accuracy less than one degree. A baseline rotation method is proposed to resolve the problem of integer ambiguities. The classical antemla swap method is simply a special case of the rotation method. The rotating character of the compass provides the convenient environment for applying the rotation technique. Such compass may replace the traditional heading devices in navigation system, such as the magnetic compasses or gyroscopes.
