摘要 结合球谐函数电离层模型,利用附加约束条件的Kalman滤波算法实现了实时求解卫星和测站接收机的硬件延迟,从而为广域增强系统的电离层延迟估计算法提供绝对电离层延迟信息。结果表明,基准站上接收机的硬件延迟可以在较短时间内收敛,卫星的硬件延迟单天最终解与IGS发布的值其差异在亚ns级。 Combined with VTEC Spherical Harmonic Function Model, the Kalman Filter with external constraint condition between some parameters solved is used for real time estimation of GPS satellite and receiver＇s Differential Code Bias （DCB）. This can be used to provide DCBs for Wide Area Augmentation System＇s real time ionosphere delay modeling. The results show that the DCB can converge in short time in this solution. The final value of those DCBs is in little bias comparing with the results of IGS.
