Analysis and Evaluation of the Positioning of Autonomous Underwater Vehicles Using Acoustic Signals
Abstract:
Autonomous underwater vehicles (AUVs) present as much potential as unmanned aerial vehicles, or drones, for being used in military missions. Major defense-oriented applications of AUVs will be intelligence, surveillance, and reconnaissance tasks, besides payload delivery and communication support. Nevertheless, AUVs have several constraints that make it difficult to rely completely on their autonomous functions. Particularly, AUVs do not have access to accurate positioning mechanisms like GPS. Thus, expensive inertial navigation techniques have been developed for these vehicles in the last decades. However, small and low-cost AUVs require newer and simpler positioning techniques that can be adapted to specific military missions. Based on that, this work analyzes and evaluates common trilateration techniques based on the propagation of acoustic signals in the water for a precise underwater positioning. Although the results show that the method known as time difference of arrival (TDoA) presents good accuracy, its application in military missions is still limited due to the large number of noise sources required; therefore, several future works in this direction are additionally proposed.
