Abstract
Currently, for the DORIS data processing with our POD software GINS we only use the ionospheric-free linear combination to eliminate the first-order term, while ignoring the influence of higher-order terms. So, as already done for the GNSS data processing, we implemented the second order ionospheric correction in GINS software for the DORIS data processing. First, we will look at the impact on Precise Orbit Determination by analyzing statistical results such as one per revolution empirical acceleration amplitudes and orbit residuals. We will also give some comparisons to the CNES precise orbit used for altimetry and external validations of our orbits will be done with independent SLR measurements processing. We will also analyze the impact on the CNES/CLS IDS Analysis Center solution in terms of origin and scale factor.
