Buoys as Maritime Signals of Opportunity. Sturdivant, D. F. & Martin, S. M. In pages 182–194, April, 2024. ![Buoys as Maritime Signals of Opportunity [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex Buoys have been a long-standing source of position and guidance information with usage dating all the way back to the 13th century. While not traditionally designed for navigation, this paper proposes the idea of exploiting modern buoys as a signal of opportunity (SOOP). The goal is to present the efficacy of buoys as compared to other accepted constellations, namely low Earth orbit satellites (LEO). Similar to cellular or radio towers, they are terrestrial emitters that would provide observability overseas. Global DOP analyses are performed to snapshot buoy availability and assess the capability of a buoy-based navigator with respect to the buoy location. A Doppler-INS, tightly-coupled, extended Kalman filter (EKF) model is developed and presented with the navigation performance being assessed by Monte Carlo simulations. When considering a simulation with adequate dilution of precision (DOP) estimates for the buoy constellation, it is found that buoy-based navigator performs comparably to LEO-based SOOP navigator.
