Assisted GPS works by providing a GPS reference network in which a series of receivers have a clear view of the sky and can operate continuously. This reference information is then made available to cellular networks such as GSM and UMTS to refine location accuracy within the sphere of location based services. This module discusses the interaction between the reference network and the Location functions within a cellular network and how these combine to offer accurate location information.
