This review paper presents a comprehensive review of low-cost underwater swarm acoustic localization systems, focusing on recent research findings validated through field experiments. To aid research on the concept of low-cost swarm acoustic localization, this article provides overview of cost-effective underwater swarm applications and the applicability assessment of traditional acoustic localization strategies, then presents several crucial components for building an acoustic ranging-based low-cost swarm localization system, including lowcost acoustic modems and low-cost swarm localization system with cooperative strategies. In summary, this review serves as a valuable resource for researchers and practitioners in underwater swarm robotics and acoustic localization, addressing challenges, strategies, and goals of low-cost swarm acoustic localization systems.en2169-353620242577925796IEEEhttps://creativecommons.org/licenses/by/4.0/Acoustic localizationacoustic modemlow-cost underwater localizationUUV SwarmEngineering and Applied OperationsElectrical Engineering, Electronic EngineeringReview10.15480/882.916110.1109/ACCESS.2024.335735910.15480/882.9161Other
