Abstract: A novel Taylor positioning scheme for underground coal mine is presented to improve the positioning accuracy. Considering the Taylor algorithm depends on the initial value highly, the algorithm uses weight and threshold to choose the initial value by excluding coordinates which are of great error and then calculate the rest of coordinates based on weight. UWB wireless positioning system is designed to achieve this algorithm, the results show that the positioning accuracy achieves 0.4 m, which demonstrates it is suitable for coal mine environment.
