Leading Edge - Got Game? GPS-enabled mobile gaming blurs the fantasy-reality line - Mobile gaming applications leverage location-based technology to pull players and the real world into virtual worlds.
A New Policy for GPS On December 15, U.S. President George W. Bush issued an important new directive reflecting a renewed U.S. government commitment to maintaining GPS as a global leader in satellite navigation
System Challenge - A New Policy for GPS - On December 15, U.S. President George W. Bush issued an important new directive reflecting a renewed U.S. government commitment to maintaining GPS as a global leader in satellite navigation.
System Challenge - Interoperability on Time - GPS-Galileo Offset Will Bias Position - Galileo and GPS will determine their system times in a slightly different manner, leading to a position bias for users of combined equipment. The authors discuss options for time-offset determination.
Design Challenge - The Enemy Inside - GPS Jammed by Room, Host, Self - Indoor GPS reception requires sensitivities 20dB below that of outdoor receivers, making it susceptible to jamming from low-power sources. Hardware designers both within and outside the GPS industry must counter with modifications for indoor locatability.
