What is vehicle tracking system based on GPS and GSM? ›

Vehicle Tracking System using GPS – Circuit Diagram

It consists of a microcontroller, GPS module, GSM modem, and 9V DC power supply. GPS module gets the location information from satellites in the form of latitude and longitude. The microcontroller processes this information and sends it to the GSM modem.

Fundamental difference

GPS uses signals coming from satellites to pinpoint the exact location or position. Whereas, GSM uses cellular signals that are from nearby base stations. So low accuracy. In GPS technology, 4 of the 24 satellites set in the orbit of Earth used to perform routing.

A GPS / GSM tracker utilizes either the Global Positioning System satellites or the Global System for Mobile Communications to determine precise location. However, while GSM and GPS tracking devices both accomplish similar tasks, they do so in very different ways.

GPS tracking is the surveillance of location through use of the Global Positioning System (GPS ) to track the location of an entity or object remotely. The technology can pinpoint longitude, latitude, ground speed, and course direction of the target.

The Global System for Mobile Communications (GSM) is based on the phone's signal strength to nearby antenna masts. An indoor location tracking map on a mobile phone. Mobile positioning may be used for location-based services that disclose the actual coordinates of a mobile phone.

The GSM module plays a crucial role in the communication between devices and the GSM network. It is responsible for establishing and maintaining the communication link between the device and the network. The module also handles the encryption and decryption of data, which ensures the security of the communication.

A GSM SIM card works for GPS by providing a means of communication between the GPS device and the cellular network.

GSM: CELLPHONE SIGNALS

GSM signals will provide an approximate location when GPS is not available. These type of signals provide signals by using cellular towers nearby, with an accuracy up to 2500 meters. If you need to find your bike, GSM will give a rough localization. This is not the most precise signal.

AT&T and T-Mobile are GSM wireless networks. Code-division multiple access (CDMA) is used mainly in the US. Verizon uses CDMA technology and is the largest wireless carrier in the US, but CDMA's market share around the world is estimated to be less than 20%.

The purpose of using GPS navigation is to reach a destination point or identifying one's own position in the map. The purpose of tracking is to identify something or someone else's position on a map.

Can a cell phone detect a GPS tracker? ›

An unknown tracker alert is sent when someone else's tracker device is separated from them and if your Android phone detects the tracker is traveling with you and out of Bluetooth range from the owner. The notification alerts you to the tracker and tells you how to find it and what to do next.

GSM tracking allows you to determine the position of a device using the coordinates of the GSM phone network cells to which the SIM card is hooked.

Vehicle tracking system or fleet management system

A vehicle tracking system is sometimes also referred to as a fleet management system, although the latter can contain more functions than just tracking the locations of vehicles.

GPS does not require any form of internet connectivity. GPS depends on signals from satellites. Anyone can harness these signals using a GPS receiver. You can test this fact by turning off the internet connection on your phone and using Google Maps.

With its simplest definition, a vehicle tracking system is the system that allows tracking and controlling of vehicles via an online computer, smart phone, tablet, etc. on a 24/7 basis thanks to GPS satellites.

A GPRS vehicle tracking system is capable of working with a GPS system or on it's own. When working in conjunction with at GPS system, the location information is captured through GPS and that information is relayed to the internet through the GPRS system.

GPS stands for Global Positioning System. whereas GPRS stands for General Packet Radio Service. GPS is used for the satellite based navigation systems, mapping as well as GIS etc. Whereas GPRS is used for video calling, Email accessing, multimedia messaging etc.

These systems make use of GPS(Global Positioning System) and GSM(Global System for Mobile Communication) technology to provide precise and constant location telematics to an individual fleet manager.
