| Abstract: | One kind of short-range precise positioning system is researched and designed. Using ultrasonic radio positioning technology, the wireless sensor networks is set up to realize the localization. It possesses such advantages as simple structure, easy realization, and not requiring clock synchronization. Aimed at this positioning system, a fast and high-precision multi-step length positioning algorithm is designed. The theoretic and experimental results show that the positioning algorithm is highly effective. |
