GPSvastuvõtjast

GPSvastuvõtjast, commonly known as a GPS receiver, is an electronic device that receives and processes signals from Global Positioning System (GPS) satellites. Its primary function is to determine the precise location of the receiver on Earth. This is achieved by calculating the distance to at least four different GPS satellites. Each satellite transmits a unique signal containing its orbital information and a precise time stamp.

The GPS receiver measures the time it takes for these signals to arrive from each satellite. By knowing the speed of light, it can then calculate the distance to each satellite. With distances to multiple satellites, the receiver can triangulate its position in three-dimensional space, providing latitude, longitude, and altitude. Modern GPS receivers are highly accurate, capable of determining position within a few meters.

These devices are ubiquitous and found in a wide range of applications. Consumer electronics like smartphones, portable navigation devices (PNDs) for cars, and smartwatches rely heavily on GPS for location services, mapping, and navigation. In professional fields, GPS receivers are crucial for surveying, geodetic measurements, precision agriculture, and fleet management. They are also vital for aviation and maritime navigation, ensuring safe travel. The accuracy and reliability of GPS have made it an indispensable technology in modern life.
