GPS is a system of 30+ navigation satellites circling Earth. We know where they are because they constantly send out signals. A GPS receiver in your phone listens for these signals.Once the receiver calculates its distance from four or more GPS satellites, it can figure out where you are.
How GPS determines a location?
A GPS receiver determines its own location by measuring the time it takes for a signal to arrive at its location from at least four satellites. Because radio waves travel at a constant speed, the receiver can use the time measurements to calculate its distance from each satellite.
It takes four GPS satellites to calculate a precise location on the Earth using the Global Positioning System: three to determine a position on the Earth, and one to adjust for the error in the receiver’s clock.

GPS Tracking System Basics
A GPS tracking system does this by using the Global Navigation Satellite System (GNSS) network. This network consists of satellites that communicate with GPS devices to provide information on the current location, direction, time, and speed of the vehicle being tracked.

Do Sat Navs need internet?
Firstly, unlike many phone apps, dedicated sat navs don’t rely on mobile data. Instead, they use GPS signalling, meaning that you don’t need to worry about your data connection disappearing or your monthly mobile data allowance running out.
Does sat nav work without internet?
Your phone contains a built-in GPS receiver that allows it to track your location without cellular service. Maps stored on your mobile device do not need internet connectivity as the routes don’t change often. This information comes together to give you the location of your device and the routes around you.

Does GPS work when car is off?
The short answer is yes, the plug-in connection GPS (OBD GPS trackers) and the hardwired GPS trackers can function without a battery as a car is able to generate electricity from both its operating engine and the car battery to power any mobile device without the use of external power sources.
Does GPS work without phone signal?

How can I tell if my vehicle is being tracked?
Get your mat, lie down with your back on it, slide under your car, and shine your flashlight into its underside. Look for any suspiciously shaped objects that don’t look like they’re part of the car, such as taped-on objects, boxes, and antennas.

How far can a GPS tracker work?
No distance limit under good gps signal. Longer answer? It depends on your software, hardware and signal. But the rule of thumb is that a real-time GPS tracking device with perfect line-of-sight cellular coverage can be accurate to 6 feet and will work anywhere cellular coverage exists.
Does a GPS tracker need a battery?
Like hardwired systems, Plug and Play GPS trackers get their power from your vehicle’s electrical system, so they don’t require batteries either.
Can GPS reach anywhere?
The Global Positioning System (GPS) is a U.S. government satellite-based navigation system that currently consists of at least 24 operational satellites. GPS works in any weather conditions, anywhere in the world, 24 hours a day, with no subscription fees or setup charges.
