Global Positioning Systems are a 24-satellite navigation system. These satellites provide time and location data anywhere and anytime, depending on the recipient’s network connectivity and GPS setup. GPS also works in all weather conditions.

GPS saves time by giving drivers, fleet managers, and the transport industry block–free and efficient routes. Furthermore, it saves lives by assisting in search and rescue operations, thus preventing accident casualties.

With advances in the environmental study industry, forecasting weather and earthquakes are possible with GPS.

This article discusses how a GPS works in a car without the internet.

Can A GPS Work In Cars Without The Internet

GPS works using a satellite signal. These signals are in the form of coordinates that users receive as a location. Thus, a car GPS is fully functional without WiFi or cellular data.

Every car has a navigation system with a map that is installed. Moreover, a registered vehicle in a given country will provide a map of that particular area.

This map may include other countries, but it will likely have every road, street, and landmark with the given coordinates of these areas. These navigational systems provide the location without the aid of the Internet.

The transmission of signals occurs from the satellite to the map. All in all, GPS helps you plan and navigate routes of choice.

Most modern cars have navigation systems that older models may not. But one can buy these and have them installed.

What Are The Reasons For Tracking A Car With GPS?

What Are The Reasons For Tracking A Car With GPS

These are the primary reasons for tracking a car with GPS:

1. Locating

If a driver forgets the location of their car, a GPS comes to their aid. Whether your vehicle is in a crowded and unfamiliar area or you don’t remember the parking spot, locating it with GPS is straightforward.

The GPS device pinpoints the accurate location of a car for the driver. Moreover, using this with an app increases its performance, making navigating hassle-free. Pre-saving locations make it easier to re-navigate them.

2. Monitoring

GPS helps users monitor other people using their cars. For instance, GPS helps track a family member without driving experience.

The user can monitor the location and speed and get updates for rash and unsafe driving. This way, GPS devices ensure on-road safety and encourage safe driving.

3. Theft

There are unfortunate circumstances where cars get stolen, and owners do not know where to start to find their vehicles.

GPS comes to the rescue here and aids law enforcement agencies in locating the car. This increases the chance of a safe recovery tenfold.

What Is The Functioning Of A Car GPS?

A car GPS uses satellite data-processing algorithms that provide precise locations to the driver. The positioning system in automobiles comprises three components – GPS receivers, maps, and navigation systems.

Your phone integrates with a GPS receiver, giving you an accurate location. Note that GPS only receives a signal and does not transmit them. The receiver calculates the position with longitude and latitude and displays the location. Remember, the GPS receiver is the positioning system that aids in positioning the signals from satellites.

A car GPS works just fine without any WiFi or cellular network. Drivers can use this to their advantage and travel in rugged/remote regions that barely have network coverage.

If car drivers need to access a map without an internet connection, there are two options:

  • Pre-loaded maps that do not need an internet connection to work
  • Downloaded/Offline maps

Thus, maps stored in your car’s navigation system do not need an internet connection. Users can also use GPS on their phones to navigate their vehicles. This way, GPS helps in navigating without WiFi.

Smartphones without WiFi work well with GPS. Google Maps on Android or iPhone devices track your steps without the internet.

What Is The GNSS Network In Car GPS?

What Is The GNSS Network In Car GPS?

GNSS (Global Navigation Satellite System) is a satellite group that provides global coverage. These satellites deliver signals, position, and real-time data to any GNSS receiver.

Keep in mind, GPS receivers use this data to give accurate locations. A car GPS uses this GNSS network, giving users or fleet drivers precise location details.

4 Criterias GNSS Uses For Location Detection

GNSS uses these four criteria to assess a car’s location:

  1. Accuracy: This shows the difference between the measured and actual receiver data.
  2. Integrity: Systems capacity in having the receiver’s data (speed, time, and position).
  3. Continuity: Refers to the system’s capabilities to function without interruptions.
  4. Availability: Time required for a signal to complete the three criteria above.

SBAS (Satellite Based Augmentation Systems) improves signal performance. For instance, the European Geo-stationary Navigation Overlay Service/EGNOS improves GPS accuracy. It corrects the GPS signal measurement errors and provides accurate information.

Pros And Cons Of Using A Car GPS Without Internet

Using a car GPS devoid of WiFi or cellular connection has both positives and negatives. Drivers can have the benefits of a GPS without worrying about the network, but there are limitations to these benefits.


  • Saves Cost: Some car owners have a shoestring budget and want to stick to it. Budgeting is possible with offline maps and GPS that save on internet costs.
  • Dependency: These days, using the internet for navigation is common. Users are highly dependent on it. Luckily, a GPS is independent of the internet. Thus, it prepares you for circumstances like poor network/signal coverage.
  • Accurate Directions: When traveling in rugged regions without network connectivity, drivers find it hard to navigate without the internet.
    But with GPS capabilities that function offline, drivers can now navigate easily.
  • Downloads: Suppose you are a frequent traveler or have been given the responsibility for fleet management. You tend to supply or visit the same places for business/leisure. Several locations can be downloaded and accessed later for navigation – provided they’re pre-downloaded.


  • No Traffic Details: When offline, getting accurate traffic information is less likely. Offline GPS makes navigation difficult, and drivers can often take the wrong route. It’s only with an online GPS that drivers get convenient route suggestions.
  • No Live Updates: Live updates are only possible when the driver uses a GPS with a network connection. They receive alerts and navigational updates. But, getting such suggestions to change routes cannot happen offline.

How Do Car Trackers Work Offline?

How Do Car Trackers Work Offline

Car GPS trackers are devices that record a vehicle’s movements on the go. Most trackers these days have a built-in GPS. With the help of satellites, these devices can track a car’s location while the GPS provides the route.

Drivers need not worry about their car’s safety or reaching lengthy destinations with multiple twists and turns. The benefits these devices offer are security, location history, and alerts. It’s helpful for drivers without WiFi as GPS works in cars without internet.

While trackers work well with network connectivity, they also work smoothly without it. Simply keep a list of downloaded locations on your GPS with the tracker working hand-in-hand with the system.

Here are some features of an offline car GPS tracker:
