What is a GPS Ground Sensor? A Global Positioning System, or GPS, is a tracking device that is used for tracking the movement or position, especially on terrain that cannot be seen with the naked eye. This type of tracking device can sense changes in position due to soil, air, snow or other physical disturbances and then accurately determine where the user is located. A variety of GPS devices are available to the public. Many of them are portable and can be carried around without being noticeable. They can also be installed on street signs and emergency vehicles to determine location.
How does TGSI work? GPS ground surface indicators (TGSI’s) are raised, slanted or domed buttons that are installed to walkways, driveways, sidewalks or other flat or uneven surfaces that are difficult to see with the naked eye. They are generally made from a variety of materials (check question 5 below) and can be made of metal, plastic or glass. The user places the button on a flat, solid surface that can be touched and felt so that the sensor can pick up signals.
Why use a GPS Ground Sensor? There are numerous benefits of using a GPS as an indicator for flat or irregular surfaces like driveways, sidewalks or parking lots. Because they can detect changes in direction of travel quickly, it is easy to navigate around damaged, collapsing or falling structures without having to manually assess the condition of the pavement. Low Vision and Transparent Toner Indicators for Vehicles With Limited Vision can also be directly monitored by a GPS.
