How GPS Trackers Work
The Basics of GPS Technology
GPS, or Global Positioning System, is a technology that helps you figure out where you are on Earth. It works by using a network of satellites orbiting the planet. These satellites send signals to your GPS device. Your device then calculates your exact location by measuring how long it takes for the signals to reach it.
Think of it like a game of catch. The satellites "throw" signals, and your GPS device "catches" them. By catching signals from at least four satellites, your device can determine your position with impressive accuracy. This process is called trilateration. It measures distances between your device and the satellites to pinpoint your location.
GPS technology doesn’t rely on internet access. Instead, it uses satellite signals, which makes it useful even in remote areas. However, obstacles like buildings or mountains can block these signals, affecting accuracy. That’s why understanding how GPS works can help you use it more effectively.
