In the same way, we presented the results of PPP-AR of 24 DF-GNSS stations during eclipse day. The time series were corrected for the common noise filter of the East, North, and Up components. The stations had variations in position within the time window of the eclipse (between 8 and 14 UT). The station with the highest positioning errors in the East, North, and Up components was PIFL stations. KAGA, GLS2, SENU, and MSBL stations also showed position variations between 5 and 8 UT.
