The DGPS approach, spatially limits the operating range of the rover receiver to about 20 km from the base stations. As a result, it increases not only the operational cost of equipment and human resources but also the logistical complexity of many applications such as land and geodetic surveying, and airborne mapping. With the increased availabiliiy of precise GPS satellite orbit and clock data with reduced latency from the International GPS Service (IGS) and many other organizations, high precision kinematic at centimetre to decimetre-level is now possible using a single GPS receiver. This paper describes a method known as precise point positioning and its application to airborne kinematic positioning. Different from the conventional DGPS approach, the new method does not need a base station since the positioning determination is based on the processing of un-differenced code and carrier-phase observations from a single GPS receiver. It therefore eliminates the dependency on base station and the rover range limitation associated with conventional methods, resulting in instant advantages in field operations. A software system that has been developed at the University of Calgary will also be described in this paper along with numerical results to demonstrate the positioning accuracy obtainable.
