Aused by switching the reference clock are fairly modest (ca. two ns
Aused by switching the reference clock are comparatively modest (ca. 2 ns), it’s worth noting that such effects aren’t clearly visible and are usually not documented in final products in any way. Moreover, the usage in the L-S strategy permits to get a determination of your periods not connected with satellites orbital movement nor with the time scale maintenance in various BDS-2 satellite clocks. This sort of phenomenon wants additional, extended investigation. The time-frequency analysis shows that the satellite clock behaviour could differ in time, and determined periods have variable amplitudes more than the analysed time span. The analysed data may possibly also include periodic components associated for the sampling interval, but this phenomenon was not analysed in this study. The presented evaluation was carried out only for the BeiDou technique. In future analysis, it is actually necessary to study this sort of phenomenon also for other GNSS systems, possibly using the use of particular software program packages created for analysis unequally spaced information (e.g., [50]) to confirm prospective limitations of your methodology made use of.Author Contributions: Conceptualization, J.K. and K.M.; methodology, J.K. and K.M.; software, J.K. and K.M.; Ziritaxestat supplier validation, J.K., K.M. and M.J.; formal analysis, J.K., K.M. and M.J.; investigation, J.K. and K.M.; sources, J.K. and K.M.; information curation, J.K. and K.M.; writing–original draft preparation, J.K. and K.M.; writing–review and editing, J.K., K.M., D.P. and F.Z.; visualization, J.K. and K.M.; supervision, J.K., K.M., D.P., M.J. and F.Z.; project administration, J.K., K.M. and D.P.; funding acquisition, J.K. and K.M.
