Aused by switching the reference clock are relatively little (ca. 2 ns), it truly is worth noting that such effects are not clearly visible and will not be documented in final goods in any way. Furthermore, the usage of the L-S approach enables for a determination in the periods not MRTX-1719 Autophagy connected with satellites orbital movement nor with all the time scale maintenance in a number of BDS-2 satellite clocks. This type of phenomenon desires further, extended investigation. The time-frequency evaluation shows that the satellite clock behaviour may perhaps vary in time, and determined periods have variable amplitudes more than the analysed time span. The analysed data may perhaps also involve periodic components related to the sampling interval, but this phenomenon was not analysed in this study. The presented analysis was carried out only for the BeiDou method. In future investigation, it’s essential to study this sort of phenomenon also for other GNSS systems, possibly with all the use of MNITMT Purity & Documentation specific software packages developed for evaluation unequally spaced information (e.g., [50]) to confirm potential limitations of your methodology utilised.Author Contributions: Conceptualization, J.K. and K.M.; methodology, J.K. and K.M.; application, J.K. and K.M.; 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.
