The accuracy of each Smart Compass unit is affected by GPS and its internal compass. Short answer: Your Smart Compass is accurate within about 16.5 feet.
Your Smart Compass has a number of features designed to optimize accuracy when it is in normal use. Simply clip a Smart Compass onto each of your companions, venture out under the open sky and play some 'hide and seek' to experience Smart Compass.
GPS satellites are operated by the US Government and broadcast their signals in space with a certain accuracy, but what you receive depends on additional factors, including the number of GPS satellites the unit is able to see in your exact location, signal blockage, atmospheric conditions, etc.
For example, GPS-enabled smartphones are typically accurate to within a 16.5 feet (5 meters) radius under open sky. However, their accuracy worsens when signals are blocked by buildings, bridges, and trees.
Smart Compass utilizes the same GPS data, so you can expect the same 16.5 feet (5 meters) accuracy for each Smart Compass unit under the same conditions. However, when 2 Smart Compasses are locating one another, the variance in accuracy can potentially double to up to 33 feet (10 meters), as described in the picture below.
It’s important to note that, because accuracy of GPS data received varies depending on your location, conditions and GPS satellite geometry, the accuracy of your Smart Compass may vary as well.
Each Smart Compass includes a compass that works alongside its GPS to provide users with the distance and direction of the members of your group. Like all compasses, the compass in Smart Compass is sensitive to electromagnetic fields or proximity to large metal objects. When using Smart Compass it is best to keep your unit it 6-8 inches from your cell phone, avoid reading when placed on metal surfaces (such as the hood of a car) and take into account large metal or magnetic structures (such as powerlines or skyscrapers) that may influence the accuracy of the compass at any given location.
Smart Compass UX : Your people are “nearby”
We designed Smart Compass for groups of people who are looking for each other. We have found that the best tool for a person to find someone just a few feet from you is to simply look around. Because of this, your Smart Compass screen will switch from distance and direction to “Nearby [Name]” when you are within 28 feet of your selected companion.
