Summary This paper presents a peer‐to‐peer cooperative positioning technique together with its performance assessment. The cooperation between the two GPS receivers is realized by means of a wireless LAN connection and is significantly influenced by the accurateness of the synchronization between the two terminals. Both the outdoor‐to‐indoor and outdoor‐to‐outdoor scenarios are considered. For each scenario, we assess the satellite signal acquisition and its computational load and the performance in terms of position accuracy and time‐to‐first‐fix of the positioning procedure.
