Location-aware technology has numerous potential applications in safety, living, and services in the shipboard environment. Fingerprint-based methods that use the received signal strength indication (RSSI) to provide high positioning accuracy have been widely adopted for indoor localization. However, the RSSI can be severely disturbed by the steel structure and dynamics of the shipboard environment, which prevents it from being implemented in shipboard localization in practice. In this paper, a novel approach, called spatio-temporal fingerprint localization, is proposed. This approach can alle...
