Julia package for providing frequency-stability test functions. Implemented so far in overlapping as well as consecutive form for phase or frequency datasets are: allan deviation, modified allan deviation, hadamard deviation and time deviation.
Fast algorithm for Fully Overlapped Allan Variance and Total Variance
A high-performance Julia library for time-and-frequency metrology and PNT. SigmaTau.jl provides a comprehensive suite of frequency stability estimators (Allan, Hadamard, Total) alongside advanced Kalman filtering and state-space modeling for atomic clock ensembles and timescale generation.
