The satellite timing service has been used widely for its high precision and low cost. Based on the periodic fluctuation of the GEO satellite one-way timing deviation, this paper explores the relationship between the phenomenon and satellite movement, and then found a very strong linear correlativity between timing deviation and signal transmission delay difference. Therefore, this paper proposes a linear delay contribution compensation model in order to reduce the cyclical influence of timing deviation. The experimental result proves that the model can modify the original timing result at most 70% and almost eliminate the periodic fluctuations.
