SnapTrack is not conventional use of GPS. It also uses the arrival time of the forward link to help to narrow down the search of the GPS signal, also reduce the number of birds from 4 to 2. With this hybrid approach, the sensitivity of the GPS receiver is also improved.

GPS is not rapid, except in the desert and with the
antenna in the right position, taped to the roof


SnapTrack can be used in heavily blocked area. NTT DoCoMo is using it for commercial daily use. And guess what there seems to be no desert in Japan. Even in those highly blocked areas, it takes just a few seconds to get the position.
