Abstract
Station-satellite DCB may be absorbed into the ionospheric delay in uncombined PPP resolution because of the direct usage of the precise clock offset production based on the ionosphere-free combination estimation. BDS station-satellite DCB is separated in this paper with the ionospheric delay estimation of uncombined PPP, analysis in results and stability is also introduced. Slant ionospheric delay is inverted with ionosphere observation and separated DCB at last.
