High-Precision Single-Frequency Point Positioning with Randomness of Ionosphere Delay Correction in Consideration

  • Promote a new single-frequency point positioning method with the ionosphere delay correction as a virtual observation and taking the statistic information of the ionosphere delay correction into consideration in the parameter estimation stochastic model,and build the mathematic model of this method.Analyze the differences and similarities between this solution and two other solutions depending on ionosphere grid model and GRAPHIC combination respectively.The experiment result shows that position accuracy of 0.1~0.2 m for the horizontal and 0.3~0.5 m for the vertical can be realized without converge of the whole China.
