gpsOne is a position location technology developed by SnapTrack, a subsidiary of Qualcomm. GpsOne is an A-GPS technology, meaning it uses GPS satellites in conjunction with land-based stations (towers) to determine a phone's location.

gpsOne uses A-GPS or Assisted-GPS to locate the phone more quickly, accurately and reliably than by GPS alone, especially in places with poor GPS reception.

Phones with gpsOne can receive raw signals directly from GPS satellites, but require a live connection to a network-based location server to do so. The location server helps the phone find the correct satellites. The location server also processes the raw signals and makes the final calculations that determine location.

gpsOne is integrated into most Qualcomm CDMA chipsets, and is the position location technology used by most CDMA carriers.
