WebDescription: This app can be used to calculate Allan variance for a time series signal at given tau values. The output includes: Overlapping Allan deviation, modified Allan deviation, time Allan deviation, Hadamard Allan deviation, overlapping Hadamard Allan deviation. … WebFeb 23, 2024 · The pink triangle is group C, representing the frequency stability of the GPS. The red diamond is group D, representing the frequency stability of the Galileo system. The dotted line shows the overlapping Allan deviation of the time deviation for each group. The Allan deviation of each group with a sampling interval of 86,400 s is given in Table 1.
