Abstract :
In this work, a peer-to-peer cooperative positioning technique is presented, implemented and tested. Cooperation between two Global Positioning System (GPS) software-defined receivers is realized by resorting to an ad-hoc WLAN. The performance of aided acquisition and positioning algorithms with fine and coarse time assistance is evaluated. The fine time assistance is achieved by an ideal off-line synchronization technique, while the coarse time one is carried out by means of Network Time Protocol (NTP).
