| Abstract: | This paper gives analytic formulas for 2-D and 3-D positioning with range measurements by geometry method. Based on these analytic solutions, an approach algorithm of pseudo range measurement positioning is put forward. Its convergence is discussed and a sufficient condition of its convergence and the method of deciding the final solution from multi-solutions are given. |
