The Concept of GPS
Global Positioning System (GPS) is a network of satellites orbiting the Earth that transmit signals to GPS receivers on the ground. This technology allows users to determine their precise location, speed, and direction of travel. GPS has become an integral part of modern life, with applications ranging from navigation to tracking, surveying, and more.
Understanding the Basics
GPS works by triangulating signals from multiple satellites to pinpoint the user’s location. Each satellite broadcasts a unique signal that includes information about the satellite’s position and time. The GPS receiver on the ground picks up these signals and calculates the distance to each satellite based on the time it takes for the signal to travel.
By measuring the distance to at least four satellites, the receiver can determine the user’s precise location using a process called trilateration. The receiver also calculates the user’s speed and direction of travel by comparing the changes in location over time.
