Vehicle Tracking System : GPS Enabled

The industry which is the first to implement a vehicle tracking systems is shipping industry, because they needed to monitor their trucks position at real time or they can track every checkpoints traveled by the tracks.
Now the Question arrives that how a GPS Vehicle Tracking System Works, Lets Know about the working of the system.
GPS (Global Positioning System) uses the Global Navigation Satellite System network (GNSS) to get data about the time, location, and its vehicle speed. The Global Navigation Satellite System network includes various satellites which transmit information to GPS gizmos by using microwave signals.
GPS based vehicle tracking system easily track locations of multiple vehicles in a real time.
It consists of a GPS device installed in vehicle and a software which collects the data and information of vehicles locations on the screen. Apart from vehicle location GPS device can also send a real time data about vehicle’s condition and specific events which are set in the GPS device.
Commonly tracked events in public transport are ignition (on/off), doors (open/closed) & vehicle’s speed.
There are two ways for the GPS tracking system :
- Active tracking.
- Passive tracking.
Active tracking – It is also known as 2-Way GPS or a real-time positioning. It records vehicle positions and sends the recorded data to a centralized database using a modem. This useful for commercial purposes because it allows checking object location in the exact time.
Passive tracking – It records vehicle position in particular time points. Trilateration method allows calculating the location of auto in time between recorded points. This type of tracking requires additional storage for recorded data, like a memory card or some internal memory.
A GPS-based Vehicle Tracking System (VTS) uses a Global System for Mobile(GSM) modem and a Global Positioning System (GPS) module for vehicle location. These system also allows performing some car controlling actions such as starting an engine and locking/unlocking doors which is very useful.
Hardware required for building a GPS Vehicle Tracking System :
- An LCD : (Liquid Crystal Display) is the technology used for displays in notebook and other smaller computers.
- A GPS module : The Global Positioning System (GPS) is a network of about 30 satellites orbiting the Earth at an altitude of 20,000 km.Once it has information on how far away at least three satellites are, your GPS receiver can pinpoint your location using a process called Trilateration.
- A GSM module : A GSM modem requires a SIM card to be operated and operates over a network range subscribed by the network operator. It can be connected to a computer through serial, USB or Bluetooth connection. GSM modem is usually preferable to a GSM mobile phone. GSM modems supports services like Telecommunication services, data services, supplementary services.
- A relay circuit : Relay is a switch which controls (open and close) circuits Electro Mechanically. The main operation of this device is to make or break contact with the help of a signal without any human involvement in order to switch it ON or OFF automatically . It is basically used to control a high powered circuit using a low power signal.
- A Micro-controller unit (MCU) :Microcontroller unit has a CPU (Central Processing Unit) in addition to RAM, ROM and I/O ports.
Best programming language:
Various languages are best suitable for programming the MCU. Some of them are Assembly language and C. Software in Assembly has fast performing time & C software is easy enough to build a tracking system. It is necessary to design a web page or create a tracking application for monitoring vehicle location by entering longitude and latitude received by the MCU (Micro-controller unit) from a GPS receiver and displayed on a LCD.
The web-based VTS consists of tracking devices placed on a car, a web application, and a central server system. Such system can be useful for shipping companies and organizations.
- A GSM module
- A GPS module
- A micro controller unit (MCU)
The software development VTS consists of:
- GSM-GPS module;
- Web application
- Database;
- Desktop application.
Web design :
On this stage web application goals are:
- Browsing account information and data tracking by clients
- Identifying tracking data from every device
- Storage of tracking information
- Displaying location
Desktop application :
The software application transmits commands to the GSM/GPS device. The device sends data and information to the application server through GPRS. Then, the application define a function and transmit data protocol.
GPS tracking devices transmit a real time data to software via cellular (GSM) network. If there is connection lost, data is stored in internal memory and transmitted when network becomes available. Modern vehicle tracking software easily allows to see and analyse data on desktop or laptop computers and Mobile devices.
Productivity & Efficiency of the System:
One of the advantages of GPS tracking systems is increased in transport related business. Ability to track commercial vehicles enables to inform customers about late delivery, changed delivery time or date in advance, predict delivery times. Tracking fuel consumption allows business to calculate exact travel costs, warn drivers about their driving style, selected routes. Many Vehicle rent company or cab services use tracking system like Ola cabs, Uber. Nowadays many transportation companies uses tracking system.
