Abstract :
A advanced triple-frequency methods for correcting higher order ionospheric refraction error were discussed in this paper since COMPASS system provides three carrier frequencies. Based on the analysis of ionospheric delay error model, the triple-frequency corrected model using COMPASS pseudo-range measurements is presented. The second-order ionospheric effect can be eliminated efficiently, and the instance illustrates the advantages and necessity of second-order ionospheric error correction in decimeter and centimeter-level high precision satellite positioning.
