Commercial GPS/GNSS receivers have become on the order of 20 to 30dB more sensitive over the last ten years. At the same time they have become smaller, cheaper and consume less power. Most of this gain is due to receiver architecture and signal processing, and not through system changes such as increased number of satellites. There are different potential areas where a receiver can be optimized in order to excel in a highly competitive consumer market. Extended correlation times make a change in the fundamental sequential-search process mandatory. Other approaches facilitate the use of cellular signals and geostationary satellite services to equip the receiver for a so-called weak-signal environment.

University of Applied Sciences Rapperswil

Heinz Mathis graduated from the Swiss Federal Institute of Technology in 1993. After several years of working as a development engineer at Ascom in Solothurn and Philips in Cambridge, UK, he returned to the ETH Zürich in 1997. He wrote his doctoral thesis in the area of signal processing in 2001 and worked for the company u-blox AG in the development of GPS receivers. Heinz Mathis has been a professor for mobile communications at the University of Applied Sciences Rapperswil, since 2002. His main interest lies in RF design and digital signal processing in the areas of mobile communications and GPS.
