What is GPS? How Do They Work?


Vehicle detection system and wireless vehicle communication network.

The GPS, or Global Positioning System, relies on satellites and has become an indispensable aid in everyday activities. It allows us to determine our exact location, track movement, and navigate from one place to another. Satellite navigation has become omnipresent in our community, from assisting us in navigating while driving to directing us on hiking paths and facilitating location exchange with acquaintances and relatives. But what is GPS tracker, and what are its applications beyond just navigation?

This blog provides a comprehensive overview of GPS tracking, including its operation and applications, especially in trucks. We will explore the various components of GPS systems, including satellites, receivers, antennas, and how to use GPS tracker. Additionally, we will discuss the applications of GPS trackers in trucks and their benefits in transportation. 

What is GPS tracker?

It is a device that employs Global Positioning System (GPS) technology to establish the exact position of an individual, automobile, or property to which it is affixed. The tracker receives signals from GPS satellites, which it uses to calculate its location and transmit the data to a central server. It allows the user to monitor and track the device’s movement in real time and receive updates on its location, speed, and direction.

GPS trackers come in different forms, from portable handheld devices to sophisticated systems integrated into vehicles or assets. They have many applications, including personal tracking, fleet management, asset tracking, and stolen vehicle recovery. GPS trackers are also used in logistics and supply chain management, providing real-time updates on the location and status of shipments, enabling better planning and efficiency. So far, what GPS tracker is must be clear to you. Now let’s know about it more deeply.

How to use GPS tracker?


How to use GPS tracker?

Using a GPS tracker is a straightforward process that involves attaching the device to the person, vehicle, or asset that needs to be tracked and then accessing the data through a web-based portal or mobile app. Here are the basic steps on how to use GPS tracker:

  • Choose the right GPS tracker: There are numerous GPS trackers accessible in the market, and selecting the appropriate one depends on your requirements and financial plan. Consider aspects like the dimensions and mass of the gadget, battery longevity, and the kind of tracking.

  • Install the GPS tracker: The installation process varies depending on the type of GPS tracker but generally involves attaching the device to the target using a magnet or adhesive. Some devices may also require wiring to a power source.

  • Activate the GPS tracker: Most GPS trackers require activation before use. It may involve registering the device with the manufacturer or service provider and setting up an account.

  • Access the tracking data: Once the GPS tracker is activated, you can access the tracking data through a web-based portal or mobile app. The data will typically include information on the location, speed, and direction of the device, as well as other details such as battery life and signal strength.

  • Set up alerts: GPS trackers often have alert features that notify you when the device enters or exits a specific area, exceeds a certain speed limit, or runs low on battery. Setting up alerts can help you stay on the tracking data and respond quickly to any issues.

  • Analyse the data: The tracking data provided by the GPS tracker can be used for various purposes, such as monitoring the movement of a fleet of vehicles, tracking the progress of a shipment, or ensuring the safety of a loved one. Analysing the data can provide valuable insights into the behaviour and patterns of the device, enabling you to make informed decisions and take appropriate action. Thus, these add more value when we talk about what is GPS tracker.

How does GPS tracking work?

The process of GPS tracking involves utilising a system of satellites, receivers, and software to pinpoint the location of an individual or device accurately. The following depicts how does GPS tracking work:

  • Satellites: The GPS consists of satellites orbiting the Earth. Each satellite broadcasts a signal that contains information about its location and time.

  • Receiver: The GPS receiver is a device that receives signals from GPS satellites. The receiver uses the information in the signals to calculate its location.

  • Triangulation: The GPS receiver uses a triangulation process to determine its location. It measures the distance to at least three satellites and uses that information to calculate its position.

  • Software: The GPS receiver is connected to software that translates the location data into a user-friendly format. The software can display the location on a map or provide other information such as speed, direction, and altitude.

  • Data transmission: GPS tracking data can be transmitted in real-time to a central server or stored locally on the device. It allows the user to monitor the device’s location in real-time or review the data later.

  • Applications: The utilisation of GPS tracking is extensive, ranging from individual tracking and administration of vehicle fleets to monitoring assets and ensuring security. It can improve efficiency, safety, and security in various industries and applications.

Benefits of GPS tracker in logistics

GPS trackers are an essential tool for the transportation industry, as they can provide valuable insights into the movement and behaviour of trucks on the road. Here are some benefits which the best GPS tracker for trucks contains:

  • Improve efficiency: GPS trackers can help trucking companies optimise their routes and reduce the time and fuel wasted on unnecessary detours. By tracking the location and speed of trucks, companies can make real-time adjustments to routes and schedules, improving delivery times and reducing costs.

  • Enhance safety: Global positioning system (GPS) monitors have the potential to enhance the security of truck operators and other drivers travelling on the highways. By monitoring the speed and behaviour of trucks, companies can identify unsafe driving practices and take corrective action. GPS trackers can also provide valuable data in an accident or other incident.

  • Prevent theft: GPS trackers can be used to prevent the theft of trucks and cargo. By tracking the location of trucks in real time, companies can quickly identify any unauthorised movements and take appropriate action. GPS trackers can also be used to recover stolen vehicles and cargo.

  • Monitor maintenance: GPS trackers can help trucking companies monitor the maintenance needs of their vehicles. By tracking factors such as engine performance and fuel consumption, companies can identify potential issues before they become significant problems and schedule maintenance accordingly.

  • Improve customer service: GPS trackers can help trucking companies provide better customer service by providing real-time delivery times and location updates. It can promote the establishment of faith and devotion among clients, which can result in recurrent transactions and favourable feedback.


To sum up, a GPS monitoring device is a potent instrument that enables real-time tracking of the movement and position of assets, individuals, and automobiles. GPS tracking systems use satellites, receivers, and software to pinpoint a device or person’s exact location. Thus, we hope to have answered the question of what is GPS tracker in detail and its applications in logistics as well.
