A cooperative localization procedure for a team of Autonomous Underwater Vehicles (AUVs) is described and experimentally evaluated. The procedure relies on acoustic communication networking among the AUVs and/or fixed acoustic nodes, and it is suitable as a low-cost solution for team navigation. Embedding the acoustic localization measurements in the communica- tion scheme causes delays and sometime loss of acoustic data, depending on acoustic propagation conditions; de- spite this drawback, the experimental results obtained show that on-board localization estimates have an esti- mated error of the order of few meters.
