Abstract
A spread spectrum sound-based positioning system is developed for an open field environment. Errors associated with wind are a major challenge for achieving high positioning accuracy with such a positioning system. Here, wind compensation using a base station configuration is proposed. Field experiments show that by using the proposed compensation method, the influence of wind can be minimized and high positioning accuracy can be achieved. Within a 30 m Ã 30 m area, the average two-dimensional (2D) positioning accuracy was within approx. 20 mm, at an updating frequency of 2 Hz. Optimization of the base station position was also investigated.
