Recently indoor positioning technologies have been studied using the acoustic signal from a smart phone. Also multi-hop indoor positioning system in which the equipments measure their relative position successively has been proposed. As the total positioning error is prone to increase due to the successively accumulated positioning error for the multi-hop system, the error analysis is required for the system design. In this paper, the absolute positioning error for the multi-hop indoor positioning equipments successively installed is analyzed, and it is verified by computer simulation. According to the results, the accumulated positioning error is linearly increased as the number of the multi-hop increases.
