Quick Overview

A GPS modem, also known as a Global Positioning System modem, is a device that receives signals from GPS satellites to determine precise geographic coordinates. These modems are commonly used in navigation systems, location-based services, asset tracking, and various applications requiring accurate positioning data.

How It Works

GPS (Global Positioning System) functions by utilizing a network of orbiting satellites. Your GPS receiver collects signals from at least four of these satellites, precisely measuring the time it takes for the signals to reach it. With this timing data, the receiver calculates its precise location via a process known as trilateration. Correcting for factors like clock errors and atmospheric delays further refines accuracy. This technology allows GPS to provide accurate real-time positioning information for navigation, mapping, and various applications, making it indispensable in modern life.
