The fifth edition of this manual for GPS use in outdoor environments is designed for potential consumers who wish to compare the coverage presented by WAAS, EGNOS, MSAS and NDGPS technologies. Lawrence Letham, an electrical engineer and patent attorney, teams with Alex Letham, a fellow outdoorsman, to provide information on choosing the best GPS receiver for the reader's needs, and how to navigate even in the most extreme weather conditions. This latest revision features new information on how to integrate GPS data with the TOPO software application and how to obtain a GPS interface with overseas systems.
