GPS / A-GPS Technology Rohde Schwarz.
Assisted GPS A-GPS is mainly used in mobile terminals to enhance performance by means of faster localization time to first fix, TTFF and higher accuracy. A-GPS uses the coordinates of the base station serving the radio cell in which the mobile terminal is located and transmits this information to the mobile terminal via an assisted channel.

Assisted GPS definitie Encyclo.
Assisted GPS, meestal afgekort als A-GPS, is een techniek waarbij plaatsbepaling door een gps-ontvanger wordt ondersteund assisted door informatie ontvangen van andere externe bronnen dan de gps-satellieten. Tijdens het opstarten bepaalt een gps-ontvanger zijn aanvankelijke positie met behulp van informatie ontvangen van de gps-satellieten over.
