How accurate is GPS?

GPS (Global Positioning System) is a satellite-based navigation system that is used worldwide for location tracking. But how accurate is GPS really? In this article you will read all about GPS accuracy, which factors influence it and how you can improve the precision.

GPS accuracy: how precise is location tracking?

The accuracy of GPS depends on various factors. In general, GPS can determine a location with an accuracy of about 5 to 10 metres. Advanced GPS trackers and special devices can even improve this accuracy to within a few centimetres.

Advanced GPS trackers use additional technologies such as AGPS (Assisted GPS) or DGPS (Differential GPS) to deliver even more accurate data. These technologies significantly improve GPS accuracy, especially in urban areas or difficult environments, such as a forest.

Factors that influence GPS accuracy

Various factors can influence the accuracy of GPS:

• Satellite coverage: The more satellites a GPS device receives, the more accurate the location tracking is.
• Atmospheric conditions: Weather phenomena such as dense cloud cover or solar flares can disrupt the signal.
• Environmental factors: Tall buildings, forests or tunnels can weaken the GPS signal and reduce accuracy.
• Quality of the GPS chip: High-quality GPS trackers with advanced chips deliver better results.
• Additional positioning systems: GPS can be combined with GLONASS, Galileo or BeiDou for even more precision.

How can you improve GPS accuracy?

There are several ways to increase the accuracy of GPS. A clear view of the sky is essential, because obstacles can block the signal. Many advanced GPS trackers offer the possibility to activate additional satellite systems such as GLONASS or Galileo for improved precision. Differential GPS (DGPS) can correct inaccuracies and enable even more precise location tracking. Regular software updates also play an important role, because updated GPS data improves accuracy. Anyone who needs extra high precision would do well to invest in a high-quality GPS tracker with an advanced chip.

GPS versus other positioning systems

In addition to GPS, there are also other systems used for location tracking. GLONASS is the Russian alternative and is often used as a supplement. Galileo, the European satellite system, offers particularly high precision. The Chinese BeiDou system is also used worldwide. An alternative is mobile positioning via cell towers, although this is usually less accurate than GPS. Wi-Fi positioning uses known Wi-Fi networks to determine locations, especially indoors. Nevertheless, GPS remains the most widely used system worldwide, especially for GPS trackers.

Buying GPS trackers with high accuracy

If you want to buy a GPS tracker, pay attention to the following points:

• Accurate GPS chip: Modern chips offer a high degree of precision.
• Support for multiple satellite systems: Trackers that combine GPS, GLONASS and Galileo are more accurate.
• Prepaid or subscription: Decide whether you want a GPS tracker with a monthly subscription or a prepaid model.
• Area of use: Choose a tracker that is tailored to your specific use (car, bike, suitcase, pets).
