1. A method for synchronizing ground power units, the method comprising:
generating, using a first ground power unit (GPU), a first output signal;
triggering a second GPU to output a second output signal;
comparing the first output signal to the second output signal to measure a phase shift; and
determining, based on the phase shift, the first output signal and the second output signal are synchronized, otherwise:
disabling the second GPU from outputting the second output signal; and
repeating the triggering, the comparing, and the determining after a period, the period based on the phase shift.
