GPS tracker, can it be tracked?

Suppose you receive a parcel.
Is there any device that will show whether the tracker is present or not?

Still such a question, how can the GPS signal be detected? i.e. fonit or not.

GPS trackers maintain a constant connection and can provide an updated location at any time. So using Raksa, Whistle RTL-SDR, HackRF, etc. etc. Any spectrum analyzer. can do your work
