Homepage: http://www.ima.umn.edu/gps/
Email: staff@ima.umn.edu

Organizers: Kai Borre, Gerard Lachapelle, Brian Leininger, Fan Liu

Description:
Among the principal topics considered will be:

Problems with reflected signals (Multipath) with respect to pseudo-range data and integrated carrier data, their mathematical characterization and methods of addressing these problems

Integrity of solutions of positioning algorithms

Resolution of the phase ambiguity in position determination

Global tomography, estimation of water content in the troposphere and the ionosphere

Additional topics: Antennas (beam pattern characterization and utilization, antenna shaping), Mathematical modeling of the GPS receiver, Avoidance of frequency jamming and/or interference, Use of dual and triple frequencies from GPS, GLONASS.
