Park underground or in a concrete garage and it is a fair worry: if GPS needs a view of the sky, does your tracker go blind the moment you drive down the ramp? Here is the honest answer, without the marketing spin.
The honest truth about GPS indoors
GPS works by picking up signals from satellites overhead. That means it wants a clear view of the sky. Drive into a multi-level garage or an underground lot with concrete above you, and that view gets blocked. In that situation, GPS position can weaken or drop out. No tracker on the market has perfect GPS reception buried under several floors of concrete, and anyone who tells you otherwise is not being straight with you. See what a GPS vehicle tracker is for how the positioning actually works.
So if that were the whole story, garages would be a real weak spot. They are not, and here is why.
What still works when GPS struggles
A good monitored tracker does not rely on GPS alone. Several things keep working even when the sky view is gone:
- Last known location. The system knows exactly where your vehicle was before it lost signal, which is a strong starting point.
- Cellular signal. Trackers use the mobile network to communicate, and cellular often reaches into places satellite GPS cannot. That connection helps locate and stay in contact with the vehicle.
- Movement alerts. The moment the vehicle is moved, the system flags it. A car does not stay underground forever; it has to come out to be driven away, and the instant it hits open sky again, GPS reacquires and the position sharpens right back up.
So the practical picture is this: a thief cannot hide your car underground indefinitely. To steal it, they have to move it, and moving it is exactly what trips the alerts and eventually restores a clear fix.
The monitored team is the real answer
This is where the service matters more than the raw signal. Our Secure Operating Center watches your vehicle 24/7. If it moves when it should not, we contact you, you do not have to notice it and call us. From there our team works the signal, the last known location, and the movement data through the recovery process, coordinating as the vehicle surfaces and the fix improves. See how police recover stolen vehicles for how that plays out.
Every tier gets that monitoring. Standard gives you monitored recovery, Secure adds two Automatic Driver Recognition tags, and Elite adds remote immobilization on top, so a stolen car can be stopped rather than just followed.
The bottom line
Can a garage weaken GPS? Yes, and we will not pretend otherwise. Does that make a tracker useless there? No. Last known location, cellular, movement alerts, and a monitored team that contacts you and drives the recovery all keep working, and the vehicle has to leave the garage to be stolen anyway. Prevention beats recovery, and a car that a thief knows is monitored is a car worth leaving alone. Compare the tiers here to see which fits your situation.
