Automatic location identifications are required for emergency calls in Japan and many other countries. However, giving a reliable position promptly is a problem in places where the global positioning system (GPS) signal is extremely weak. We propose an acquisition scheme for assisted GPS (AGPS) architecture based on a timingsynchronized mobile network. System errors as well as code uncertainty range are discussed. With this method, the C/A code search range is significantly reduced, and long… Expand

TLDR
This advanced tutorial will describe the GPS signals, the various measurements made by the GPS receivers, and estimate the achievable accuracies, and focus on topics which are more unique to radio navigation or GPS. Expand
Sensitivity of GPS Acquisition to Initial Data Uncertainties
TLDR
The Doppler estimate is most sensitive to both kinds of initial errors when the satellite is directly overhead, implying that the common practice of acquiring the highest satellite first needs to be reexamined. Expand
