摘　　要：在利用多站GPS数据建立电离层延迟模型时,将卫星硬件延迟和接收机硬件延迟作为整体参数求解并剔除会产生与实际不符的情况,因此将二者分离是十分必要,笔者给出了最优信息扩散估计与广义逆结合分离硬件延迟的基本方法,并结合实例对该方法进行了探讨。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.
