Abstract The satellite clock error which includes satellite differential code bias(DCB) in observation model of precise point positioning is analyzed and the expressions of DCB is given when satellite clock error being corrected by IGS precise clock products. Experimental results show that in staticly positioning the influence of DCB error is very small, so it can be ignored, but in dynamicly positioning it can make the postioning results some centimeter error, so it must be dealt with carefully.
Key words ：
