GPS stands for Global Positioning System.
The Global Positioning System (GPS) is comprised of 24 U.S. government-owned satellites that circle 12,000 miles above the earth in precise orbits so that several are always in view from any position. The system is designed to provide worldwide positioning services with an accuracy ranging from 10 to 15 meters. Instant location information enables users to ascertain exactly where their vehicles or assets are at any time, anywhere in the world. Due to minor timing errors and satellite orbit errors, however, more precise accuracies are unattainable with standard GPS. Atmospheric conditions can also affect GPS signals and their arrival time on Earth.
There are two GPS services in operation: – Precise Position Service (PPS): This service is used by the U.S. Department of Defense and authorized associates for security purposes. – Standard Positioning Service (SPS): This service is available at no charge to all worldwide civilian users. Initially designed as a military system by the U.S. Department of Defense to improve tracking capabilities of its targets, GPS has developed into a worldwide utility with multi-use services from stand-alone applications to integrated, more embedded ones. Every manmade innovation from cars and planes and ships down to cell phones and wristwatches can be outfitted with GPS technology. Over the last decade, increasing numbers of emergency, business and even family vehicles carry GPS devices and systems for their various tracking needs.
Our GPS receiver has a small antenna that receives signals from a constellation of GPS satellites. Using the timing of signal reception from multiple satellites, the receiver calculates its own position and speed. The radio transmits the calculated values back over a satellite network. Location and course data is then uploaded to our servers.
Fleet managers can monitor vehicle movement on maps and generate reports displaying route details, stop location/duration and other valuable information.
