GPS Tracking System
What is a GPS tracking system? Typical GPS tracking systems used in commercial fleet management have two core parts: location hardware (or tracking device) and tracking software. This combination is often referred to as an Automatic Vehicle Location system (AVL).
GPS Tracking Unit (GPS Tracker):
A GPS tracking unit makes use of the Global Positioning System (GPS) to determine the location, speed, direction of a vehicle, person, or assets to which it is attached and to record these data at regular intervals. The recorded data can be stored within the tracking unit or transmitted to a central location data base, or internet-connected computer, using a cellular (GPRS or SMS) normally in the unit. This allows the asset’s location to be displayed against a map backdrop either in real time or when analyzing the track later, using GPS tracking software.
A GPS tracker essentially contains a GPS module to receive the GPS signal and calculate the coordinates, speed, direction (we can GPS data), and a GSM/GPRS module to transmit GPS data to a central computer either via SMS or via GPRS in form of IP packets.
Types of GPS Tracker:
A GPS logger simply logs the position of the device at regular intervals in its internal memory. Most GPS loggers have either a memory card slot, or internal flash memory and a USB port. Some act as a USB flash drive. This allows downloading of the track log data for further analyzing in a computer. The track list or point of interest list may be in GPX, KML, NMEA or other format.
In some Private Investigation cases, data loggers are used to keep track of a target vehicle. The PI need not follow the target so closely, and always has a backup source of data
Data pusher is the most common type of GPS tracking unit, used for asset tracking, personal tracking and Vehicle tracking system. This kind of device pushes (i.e. “sends”) the position of the device as well as other information like speed or altitude at regular intervals, to a determined server, that can store and instantly show and analyze the data.
To understand how the GPS tracker works, let’s say it is a GPS navigation device and a mobile phone sit side-by-side in the same box, powered by the same battery. At regular intervals, the phone sends a text message via SMS (to User Cell phone) or GPRS (to Server), containing the data from the GPS receiver.
Web Tracking Centre (GPS Tracking Software)
Web tracking center is mostly called GPS tracking software or Fleet Management System, which is used to receive GPS data from GPS tracker and then analyze and calculate. It is installed on a server with fixed IP and broad bandwidth to enable any users to login, track and manage.
Types of GPS tracking software:
Paid and Free
Paid tracking software need pay either monthly or yearly charge for tracking on supplier’s server. Price is charged by device amount, the more the cheaper.
Free tracking software does not need pay anything, but functions are limited, like the Free tracking service provided by GPSgate.
Basic and Advanced
Basic tracking software offers limited functions which are not practical in common usage, like fleet management, personnel management. Normally the functions are Real time tracking and History playback.
Advanced tracking software offers wide range functions to enable bulk fleet management, multi-user management, remote fuel consumption management, remote scene view, etc.
