What Is a GPS Tracker?
A GPS tracker is a device that uses the global positioning system (GPS) to determine location information. GPS measures location through a network of artificial satellites.
GPS trackers provide real-time location data, essential for emergency response in cases of theft or accidents. They are also valuable for tracking the whereabouts of vulnerable individuals like the elderly or children, and for sending alerts based on specific conditions such as exiting a designated area or exceeding a speed limit. However, GPS signal reception may be limited in certain environments like indoors or within tall buildings.
Uses of GPS Tracker
GPS trackers are used in various scenarios:
1. Object Tracking
Vehicles, delivery fleets, and ships can be tracked for real-time location, aiding in theft recovery, delivery management, and operational status monitoring. Additionally, GPS trackers help in ecological improvements by optimizing routes and monitoring fuel consumption.
2. Human Tracking
They are used to monitor children, the elderly, mountaineers, travelers, and workers within facilities for safety and location management.
3. Asset Management
GPS trackers attached to valuables like jewelry and artwork aid in location identification in case of theft.
4. Pet Management
For pet owners, GPS trackers help locate lost pets, especially in unfamiliar areas or during natural disasters.
Principles of GPS Tracker
A GPS tracker determines location by processing signals from GPS satellites using triangulation. It measures signal arrival time and strength to estimate distance from satellites and calculate its position. This location data is transmitted in real-time, enabling monitoring and recording of the tracker’s location.
How to Choose a GPS Tracker
Consider these factors when selecting a GPS tracker:
1. Purpose
Define the specific use case to determine necessary features and characteristics.
2. Position Accuracy
Ensure the tracker provides high position accuracy for reliable location information.
3. Communication Method
Choose a tracker with a communication method suitable for your location and network availability, such as GSM, 3G, 4G, or internet connectivity.
