Title: Analysis of GDOP Minimum Value for Autonomous Navigation Based on the Walker Constellation
Abstract: Geometry of measuring satellites has important implications for precision of the autonomous orbit determination.Currently,the affecting of the geometry for terrestrial receiver and a navigation satellites on the positioning precision are measured mainly by the GDOP.The lower limit of GDOP limits the measurement accuracy of a positioning accuracy range of the user.Constructing navigation constellation of Walker configuration determines the boundaries for taking the minimum value of GDOP of the terrestrial receiver.To promote the use of autonomous navigation environment,uniform sampling and genetic algorithms are used get the minimum GDOP independently.Simultaneously,the simulation data verfies the correctness of the minimum GDOP.
