Highly Integrated Chipset for GPS Receivers Using RISC

This paper describes the implementation of a very highly integrated chipset for Global Positioning System Receivers for high performance at low cost. The products described include a CMOS multi- channel correlator and a 32-bit RISC Processor (ARM60) for GPS signal processing. The use of these parts, with a silicon integrated RF downconverter (or front end) GPlOlO, can form the basis of a low cost GPS chipset. Future trends in the development of GPS receiver technology are also discussed for commercial applications,
