Abstract
The aim of this paper is to analysis the new assisted GPS (A-GPS) architecture based on SUPL (Secure User Plane Location). This architecture improves performance of A-GPS based location estimation approaches. 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. We have also examined the effectiveness of initial position estimation on the TTFF and the accuracy of calculated position. Field tests are conducted on a real GSM network in urban areas and indoor environments. Executed analysis has provided that the developed SUPL based A-GPS system achieves high-performance on estimation accuracy and faster TTFF.
