| Summary:

As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the
leading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers
will use very-long-baseline interferometry (VLBI) to localize FRBs with
milliarcsecond precision. The CHIME site uses a passive hydrogen maser
frequency standard in order to minimize localization errors due to clock delay.
However, not all outrigger stations will have access to a maser. This report
presents techniques used to evaluate clocks for use at outrigger sites without
a maser. More importantly, the resulting algorithm provides calibration methods
for clocks that do not initially meet the stability requirements for VLBI, thus
allowing CHIME/FRB Outriggers to remain true to the goal of having
milliarcsecond precision.
