Abstract: With explosive growth and integration of many interfacing discipline, such as communication, computer science,space science, marine sciences, geosciences and so on, people have made the most use of the ionosphere to establish long distancecommunications, over-the-horizon detection , large-scale activities such as navigation, ionosphere and the human impact on the livesof production also have become increasingly prominent. At the same time, due to the ionosphere to the complexity of their structure,leading to the characterization and prediction model has brought a lot of inconvenience and greater error. To be able to make betteruse of the ionosphere, and further study the ionosphere model it is particularly important. Suited to China's ionosphere on thecharacteristics of the ionosphere model, focused on the model of the relevant parameters of the simulation and discussion. China'sfirst analysis of the characteristics of the ionosphere and choose a more appropriate method and then select a set of measurementsand data features based on the establishment of a statistical model and finally the use of Matlab model of the relevant parameterssimulation, And the IRI model, the circumstances of the error.
