摘要：
The normal sidereal filter is modified, and a way to calculate the mean satellite orbit period by dividing broadcast ephemeris is provided, which is checked through comparison with examples. From the results we can see that, compared to the pre-revision sidereal filter, the modified one can improve the positioning accuracy more efficiently, the accuracy of NEU directions are increased 4.5%, 5.2% and 6.2% respectively, and it has better performance between frequencies of 0.001-0.08 Hz.
