Artificial Immune System and its Applications in GPS Single Frequency Precise Point Positioning

摘要：

The natural immune system is a robust andpowerful information process system that demonstratesfeatures such as distributed control,parallelprocessing and adaptation.Artificial Immune Systems(AIS)are machine-learning algorithms that embodysome of the principles and attempt to take advantagesof the benefits of natural immune systems for use intackling complex problem domains.Using the artificialimmune algorithm in GPS data Processing can solvethe GPS nonlinear models directly and avoid the ill-conditions.The principle and algorithm steps of the AIS areintroduced and its application in GPS singlefrequency precise point positioning(PPP)is discusseddetailed.Numerical result shows that the singlefrequency PPP model solved by AIS can reach anaccuracy of sub-meter level.
