MySafeBase Smartphone Vehicle and Fleet GPS/AGPS Tracking.

Global Positioning System and Assisted Global Positioning System.

GPS devices determine location information by directly communicating with satellites moving around the earth. AGPS devices determine location information from network stations (BTS/NodeB/eNodeB) based on GSM, CDMA, or LTE technology employed in the mobile terminal. Base station systems in the A-GPS technology in turn communicate with satellite and keep the information ready and provide the information to the mobile terminals upon request.

As GPS devices communicate with satellites, they can get information only under clear sky conditions and when the satellite is reachable without any interference. As a result, devices can be slower in responding to the requested information relay service. While A-GPS devices are communicating with network stations, they get information even in cloudy weather and poor network conditions but may encounter problems when the network is not reachable. Under these conditions, AGPS devices fall back to GPS, if available, to provide location information. A-GPS devices are faster because they do not have to go to a satellite for information.
