SUMMARY:CASPER Seminar: Trevor Garner, Space & Geophysics Laboratory, UT:"GPS' Role in Ionospheric Observations and ARL's Role in GPS"
DESCRIPTION;ENCODING=QUOTED-PRINTABLE: The Earth’s ionosphere is the layer of plasma in the upper atmosphere, and it interacts with both ground and satellite-based radio signals. In particular, the ionosphere can be a major error source for the Global Positioning System (GPS), a satellite-based navigation system. Conversely, GPS error mitigation techniques can be inverted to make GPS the most abundant source of ionospheric measurements. The Applied Research Laboratories (ARL) at the University of Texas has been involved with GPS since the early 1980s, and is now involved with many aspects of GPS including constellation and signal monitoring and ionospheric determination. This talk will introduce the technique for measuring the ionosphere from the GPS signal, and some of the major research efforts using GPS signals at ARL.=0D=0A=

Dr. Trevor Garner is a research associate at the Applied Research Laboratories, at the University of Texas. He received his PhD in space physics from Rice University in 2000, his MS in space science from the University of Michigan in 1995, and his BS in physics from the University of Alabama-Huntsville in 1993. Dr. Garner has been actively involved in space physics research for the last twenty years. Presently, his research focuses on working with transionospheric signals including operating a global network of UHF/VHF receivers.=0D=0A=
