How GPS Works: The Technology Behind the Magic
Understanding how a GPS tracker works helps you choose the right device and use it effectively.
The Satellite Network
The Global Positioning System consists of:
- 31 operational satellites in Medium Earth Orbit
- Atomic clocks are accurate to 1 nanosecond
- Ground control stations that monitor satellite health
The Tracking Process
Step 1: Signal Reception Your GPS tracker receives signals from at least 4 satellites simultaneously.
Step 2: Distance Calculation The device measures how long signals take to travel from each satellite.
Step 3: Location Triangulation Using the distances from multiple satellites, the device calculates its exact position.
Step 4: Data Transmission The location data is sent to cellular towers, then to your smartphone app.
