Accurate GLONASS Time Transfer for the Generation of the Coordinated Universal Time

GLN L1C time links OP-PTB and Time deviations for UTC 1009 and 1109.

(a) GLN L1C time link OP-PTB 1009 where all the frequency biases have been corrected

(b) Comparison of the time deviations 𝜎_𝑥 of the same data as in Figure 5(a) before and after correction for all the frequency biases. Here h stands for hour, d for day, d/2 for half day, 3d for three days, and wk for a week. The x and y axis are labeled with log numbers and those in the graph are the real numbers. The same notations are used in all the TDev plots below

(c) Comparison of the Time deviations 𝜎_𝑥 of the same baseline before and after correction for all the frequency biases (here 1109 is one year after 1009 as shown in Figure 5(b))
