Did you know that about 60% of American drivers use a GPS device at least once weekly? Improving navigation skills and understanding where you are can make all the difference. In navigation technology, GPS is one of the most famous acronyms. 

But GPS isn’t the only game in town. GNSS is making its way to provide better navigation services.

Many people use these technologies hand in hand. But these two PNT satellite systems differ in function, precision, and cost.

Keep reading to learn everything you need about the differences between GNSS vs GPS.

What are GPS and GNSS?

GPS, or the Global Positioning System, is a type of GNSS owned and operated by the United States. GPS was for military use first and later made available for civilian use. 

GNSS, or Global Navigation Satellite System, is a constellation of satellites transmitting signals. It includes the Russian GLONASS system and European Union’s Galileo. In Asia, there are China’s BeiDou and the Japanese QZSS. 

Meanwhile, GPS only uses the American NAVSTAR constellation. The signals pass through receivers to determine their exact location, velocity, and time. 

The Common Applications for GNSS vs GPS

GNSS provides accurate real-time positioning data for various applications. This applies to automotive navigation, maritime navigation, aviation, surveying, and mapping. In contrast, GPS is a common GNSS system that provides accurate real-time positioning.

Another benefit of GNSS and GPS is their potential for improving transportation. This is by making it possible for vehicles to know their precise location at all times.

These systems can further reduce traffic congestion and accidents. This is efficient in maximizing limited resources such as roadways and parking spaces.

You can use GPS in car navigation systems, smartphones, or geolocation-based check-ins. GNSS and GPS can also help reduce environmental impact. This is by enabling more fuel-efficient routing and idling times.

GPS technology is also valuable for applications like military tracking. They use GPS mcode for their simulations, offering them more accurate and precise information during training.

Which Has Better Accuracy?

GNSS provides more accurate positioning information than GPS because it uses more satellites. The added satellites provide better calculated positioning information using many signals. It increases the accuracy and reliability of GNSS receivers.

Security Differences Between GPS vs GNSS

The US government uses and operates GPS systems and is vulnerable to manipulation. At the same time, several countries operate GNSS systems, making them more resistant to interference.

Also, GPS uses older signals that are more susceptible to jamming and spoofing. In comparison, GNSS uses newer signals more resistant to these threats. Finally, GNSS is replacing GPS as the primary global navigation system in the future.

Never Get Lost By Learning GNSS vs GPS Systems

GPS provides critical positioning information that helps users determine their location. Its applications include automotive, maritime navigation, surveying, and aviation. 

GNSS is a newer technology that offers more accurate positioning information. Today, sophisticated applications such as precision farming and autonomous vehicles use this.

GNSS will replace GPS in many applications in the future. Still, learning about GNSS vs GPS technologies is essential for positioning and navigation.
