Method and device for realizing prediction of observation value of tracking station

A device for realizing prediction of an observation value of a tracking station, comprising a determining module, an obtaining module, and a prediction module, wherein

• the determining module is configured to determine an observation value of a current epoch of a tracking station cannot be used in data processing;
• the obtaining module is configured to obtain variations between following epochs:
• a variation of a geometrical distance from the tracking station to a satellite between the current epoch and a reference epoch, a variation of a tropospheric error and a variation of an ionospheric error between the current epoch and the reference epoch, and a variation of a clock bias of the satellite between the current epoch and the reference epoch;
• and
• the prediction module is configured to estimate the observation value of the current epoch according to an observation value of the reference epoch of the tracking station and the obtained variations.
