Abstract
In order to improve the efficiency and accuracy of GPS height fitting.In this paper,the use of several common algorithms of standard BP neural network was improved, combined with the control network measurement examples,respectively using the match precision and match accuracy,the testing step size and running time four indicators,evalu-ates the results of fitting.The results show that the improved algorithm design can effective-ly improve the fitting precision and efficiency,in the actual engineering practice,the project can according to the specific fitting to take appropriate algorithm to improve the BP neural network.关键词
