A GPS antenna is a device that receives signals from Global Positioning System satellites to determine precise location information. These antennas are designed to pick up weak signals transmitted from satellites orbiting the Earth, allowing devices like smartphones, vehicles, and navigation systems to calculate their position accurately. GPS antennas come in various shapes and sizes, depending on their intended use. Some are built into devices, while others are external and can be mounted on vehicles or buildings. The quality and design of a GPS antenna can significantly affect the accuracy and reliability of the location data it provides.
