RFGPS Tracking System: How it Works
Advertisement
This page provides a basic overview of GPS tracking systems, including GPS vehicle tracking and GPS personal tracking applications. It also lists some manufacturers of GPS trackers.
A GPS tracker is a device, either carried by a person or installed in a vehicle, that uses the Global Positioning System (GPS) to determine its location. This location information can be stored within the device itself or transmitted to a central database. The data transfer often happens over a cellular network to a computer or mobile device connected to the internet. Once the device is with a person or installed in a vehicle, its position can be tracked using GPS tracking software.
Figure 1: GPS Personal and Vehicle Tracking System
Figure 1 illustrates the processes involved in how a GPS tracking system operates:
-
Step 1: As shown, the GPS device obtains location information (latitude, longitude, and height coordinates). Both personal tracking (1b) and vehicle tracking (1a) are represented.
-
Step 2: The location information is then transmitted to a cellular tower (GSM, CDMA, LTE).
-
Step 3: The information is transmitted as SMS messages or IP packets to database servers.
-
Step 4a: If the information is in the form of SMS messages, it’s passed to a smartphone or mobile phone once it’s powered on.
-
Step 4b: If the information is in the form of IP packets, it’s displayed when a laptop or computer user opens GPS tracking software to check the location.
The user (via laptop or mobile) can also initiate a GPS location request to track a specific GPS device. The GPS device then transmits the information as outlined in steps 1 through 4.
