%X 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 polynomial 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 satellite coordinate calculated by direct computation method show that RBF neural network interpolation method can avoid the RP,improve the interpolation stability and accuracy as well meet the demands for GPS point positioning.
