利用RBF神经网络对GPS广播星历插值
INTERPOLATION TECHNIQUE BASED ON RBF NEURAL NETWORK OF GPS BROADCAST EPHEMERIS
摘要
Abstract
Using the RBF(Radial Basis Function) neural network to interpolate the GPS satellite coordinate computed by broadcast ephemeris was proposed in order to solve the problem of Runge Phenomenon ( RP) in poly-nomial interpolation. The GPS satellite coordinate calculated by GPS broadcast ephemeris in 25th, July 2011 were selected to test the RBF neural network interpolation method. The interpolation results compared with the GPS sat-ellite coordinate calculated by direct computation method show that RBF neural network interpolation method can a-void the RP, improve the interpolation stability and accuracy as well meet the demands for GPS point positioning.关键词
