When investing in a tracking device for a vehicle, the obvious thought that comes to mind is: exactly how accurate are these trackers? Whether you're a business seeking a fleet tracker or simply require the best GPS tracker for vehicles, understanding GPS accuracy will enhance your decision-making process.

Let's take a closer, more scientific look at GPS accuracy and the factors that influence the accuracy of a vehicle tracking system.

What do we mean by GPS Accuracy?

GPS accuracy refers to the closeness of the reported location of your vehicle, or object, to the true location of your vehicle, or object. It enables modern GPS for vehicle tracking systems to typically achieve GPS accuracies ranging from 3 to 5 meters under ideal conditions. This distance is similar to the size of a small parking spot.

It is very easy for the accuracy number to vary significantly based on conditions. You can think of GPS accuracy like a target; sometimes you hit the bullseye and sometimes you're a little off the mark. The goal is for the location accuracy to sit as close to the center as possible.

The Science Behind GPS Positioning

The GPS technology operates by accessing satellites situated above the planet. Your best GPS tracking device for vehicles typically identifies signals from at least four satellites to determine its precise location through a process known as trilateration. This is where it starts to get interesting. The more satellites your device can "see," the more accurate your location is.

The strategy of multi-constellation also explains why GPS tracking gadgets are much more accurate today than in the past. Just like ShadowGPS devices, which can leverage recent technology to provide accurate and reliable positioning capabilities.

Factors that Impact GPS Accuracy:

1. Environmental Conditions

Weather can also have an unexpectedly significant impact on device accuracy. If it is raining or snowing, or due to atmospheric conditions, GPS satellite signals may be susceptible to potential blockage. Today's GPS for vehicle tracking systems has mechanisms to mitigate the effects of weather.

Urban environments have their own issues. Tall buildings can create "urban canyons" that either block, reflect, or cause satellite signals to experience what's known as multipath errors. In which your device's GPS is receiving a signal that bounces off buildings and, for a very short time, creates accuracy issues.

2. Satellite Geometry

The positioning of satellites in the sky impacts accuracy. When satellites occupy various areas of the sky, your tracking device for vehicles receives improved triangulation. When satellites are clustered in a small area, accuracy can suffer.

This is why GPS accuracy can fluctuate during the day, as satellites move across the sky. The great news is that these modern systems will automatically adjust for these variations.

3. Device Quality and Technology

Not all GPS trackers are created equal. The best GPS tracker for vehicle applications will feature:

● High-sensitivity receivers

● Advanced antenna design

● Real-time error correction

● Multi-constellation support

ShadowGPS products incorporate these advanced features to ensure maximum accuracy across different conditions and environments.

Real-World Accuracy Expectations

- Urban Environments

In urban areas, high-quality GPS for vehicle tracking systems can expect an accuracy of 3-8 meters. Although buildings affect signals, most new devices can operate successfully in urban environments.

The first step is to find a tracking device for a vehicle that has been specifically designed for urban use. Features like Assisted GPS (A-GPS) can help improve accuracy in stressful environments.

- Rural Vehicle Tracking GPS

Typically, rural areas present the best GPS accuracy results, achieving accuracy of 1-3 meters. With a clear view of the sky and very few obstructions, your best GPS tracking device for vehicles will function optimally.

Driving on the highway usually yields good accuracy results, as there are fewer obstructions between your vehicle's tracker and the satellites in the sky.

- Challenging Conditions

Some situations can temporarily reduce accuracy:

● Dense forests where tree coverage blocks satellite signals

● Underground parking garages

● Tunnels and overpasses

● Severe weather conditions

Even the best GPS tracker for vehicle monitoring will experience reduced accuracy in these situations. However, quality devices quickly regain precision once conditions improve.

Understanding Different Types of Accuracy

- Static vs. Dynamic Accuracy

Static accuracy refers to the GPS tracker's ability to determine a position when it is stationary. Dynamic accuracy is GPS positioning accuracy while the vehicle is in motion.

Moving vehicles generally have better accuracy because their changing position provides the opportunity for the GPS to use error correction and improve computational accuracy. Your GPS for vehicle tracking systems works more efficiently when it is in motion, resulting in more accurate readings.

- Horizontal Accuracy vs Vertical Accuracy

Most tracking devices for vehicle applications are primarily concerned with horizontal accuracy (latitude and longitude). In contrast, vertical accuracy (altitude) is not typically as precise or as important for a vehicle tracking system.

In terms of vehicle security and fleet management, horizontal accuracy is good enough within 3-5 meters for all practical purposes.
