'Unlike anything we have seen before': Astronomers discover mysterious object firing strange signals at Earth every 44 minutes

That assumes this is a permanent feature of the object and not episodic or something. It could be that this only happens for a decade every 100,000,000 years, and we just happened to catch it when it reached us. Or it could be aliens.

This next bit is my understanding of things and may not be entirely accurate:

But we use quartz crystal vibrations for time increments, because that doesn’t vary much, and there’s a specific clock used as the baseline I believe (similar to the international weight standards). Quartz crystal vibration is both well understood, and rapid enough to use as sub-seconds, making it far more accurate than something going every 44 minutes.

GPS is a largely standalone thing that triangulates your position with multiple satellites, and while it does use time for determining position (based on ping time or something similar), it only needs to be relative to the other satellites, IIUC. But it’s also in such rapid increments that 44 minutes wouldn’t be terribly helpful.

So I don’t think it would be worth doing since our present system is good enough, and the signal might stop as soon as we build the new infrastructure. Much better to use something we have control over, and understand better, if it’s going to be used directly in daily life on earth.
