Application of optimal information diffusion estimation for hardware delay separating of GPS

WEN Hong-feng,HE Hui(Institute of Surveying and Mapping of Chongqing,Chongqing 400014,China)  
The satellite hardware delay and receiver hardware delay as a whole to solve and remove could be inconsistent with actual values,when establishing ionospheric delay model by multi-station data of GPS,so it is necessary to separate them.A basic method,separating hardware delay by Optimal Information Diffusion Estimation Method and Generalized Inverse was given,and discussed with examples.
