Abstract
The main purpose of this paper is to realize a new assisted GPS (A-GPS) architecture based on SUPL (Secure User Plane Location). This architecture provides very good accuracy in location estimation. We provide comparative field test results of the developed system with the conventional GPS in terms of both the position accuracy and the TTFF (time to first fix) delay times. Field tests arc conducted on a real GSM network in urban areas and indoor environments. Results show that the developed SUPL based A-GPS system achieves very good estimation accuracy and faster TTFF enabling high-performance mobile positioning for location based services.
