- Abstract
- This paper presents an IR-UWB system with its performance enhanced using a fused algorithm of direct solution and iterative least square. The UWB system has an advantage of high accuracy compared with the other positioning system. When the calibration of measured distances between mobile tags (MT) and fixed anchor nodes (AN) is executed, the improvement of accuracy can be obtained on the condition that measured data are adjusted to satisfy the predetermined reference to be set in advance. At the testbed, as a MT is moved around following the guided path, its positioning cab be tracked with a small error using the enhanced indoor ranging and positioning algorithm.
