Executive Summary

To provide services for other applications, promoting the availability of Global Positioning System (GPS) is very important. While in the urban environments or with the high power malicious interference, GPS signal is shaded by buildings or overwhelmed by interference. Hence the receivers may not acquire correct Pseudo Random Noise (PRN) codes. Assisted GPS (A-GPS) technologies can solve the shaded problem, and antenna array with Adaptive Digital Beam Forming (ADBF) or SpaceTime Adaptive Processing (STAP) has been proved the effective methodology for interference suppressing.
