How does a GPS tracker work?
GPS tracking technology has transformed how we track vehicles, assets, and individuals. Yet, how does a GPS tracker works? Knowing how it works can assist individuals and enterprises to get the most out of it.
The Working Principle of GPS Tracking
A GPS tracker works with the Global Positioning System (GPS), a system of satellites that constantly sends signals to Earth. The device receives these signals and calculates their exact location using a process known as triangulation or trilateration.
Step-by-Step Functioning of a GPS Tracker
Reception of Signals from Satellites:
- GPS trackers use a minimum of four satellites to compute their precise location.
- The tracker receives time-stamped location information from the satellites.
Calculation of Location:
- The GPS tracker computes the received signals to ascertain latitude, longitude, altitude, and speed.
- It employs triangulation, in which the device calculates the distance from several satellites to determine its precise location.
Data Transmission:
- Once they establish the location, the GPS tracker sends data to a central server via cellular networks (SIM-based trackers) or satellite communications.
- Users can view the data through mobile applications, web interfaces, or software platforms.
Real-Time Monitoring & Alerts:
- Subscribers can view real-time location, history of movement, and geofencing alerts.
- In the event of emergencies, GPS trackers can issue SOS alerts or alert subscribers regarding unauthorized movements.
- Types of GPS Trackers Based on Connectivity.
- Active GPS Trackers: Send real-time location updates continuously.
- Passive GPS Trackers: Log location data to be retrieved later when it is connected to a computer or cloud-based service.
Applications of GPS Trackers
- Vehicle Tracking: Helps in tracking fleet movement, fuel consumption, and driver habits.
- Personal Safety: Used to follow children, elderly people, and adventure tourists.
- Asset Protection: Protects valuables such as shipments, cargo, and high-value equipment.
- Pet Tracking: Tracks where pets are, lowering the risk of them getting lost.
Conclusion
GPS tracking sends satellite signals, determines position, and communicates data for real-time monitoring. The GPS tracker increases security, efficiency, and peace of mind for personal security, fleet management, or asset tracking. As developers make continuous GPS advances, GPS tracking becomes ever more precise and diverse in. application.
