Abstract:
Commercial GPS/GNSS receivers have become on the order of 20 to 30dB more
sensitive over the last ten year. 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
Biography:
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, U.K, 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 lecturer 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.
