| Abstract: | Three key factors are discussed, which affect positioning accuracy of range- range positioning mode and hyperbolic positioning mode. Based on the error elliptical theory, the expressions of positioning error and of positioning geometric factor of range range positioning mode and hyperbolic positioning mode are derived, and the positioning error and the blind pasitioning area of two different positioning modes are analyzed. According to the requirement of navigation area, an optimum positional configuration among navigation stations of hyperbolic positioning mode is provided. Some considerable conclusions are obtained, and some graphs of distribution are presented, which are important to study and design a reasonable, precise radio navigation system. |
