A Cure for Urban GPS: A 3-D Antenna

Finally it’s here, solutions to GPS connectivity flaws in dense urban areas.

More and more technology relies on GPS location readings, but the technology remains unreliable in dense urban areas.

Good GPS readings are hard to get in cities because of the multipath phenomenon: signals from positioning satellites bounce off buildings and other structures. That confuses GPS receivers, which calculate their location by knowing exactly how long it took for signals to arrive from satellites overhead. 

A signal that has bounced takes longer to arrive than it would if it had travelled directly, muddying a receiver’s math and sending location readings off by tens or hundreds of meters. 
Smartphones and in-car GPS units often have to work out their true location by analyzing maps and by getting a series of readings over time.
