Positsioneerimissüsteemidega, tuntud ka kui positionering systems, are technologies used to determine the location of an object or person. These systems are crucial for a wide range of applications, from navigation and surveying to logistics and asset tracking. The most common type of positioning system is the Global Navigation Satellite System (GNSS), which includes the Global Positioning System (GPS) operated by the United States, GLONASS by Russia, Galileo by the European Union, and BeiDou by China. These systems rely on a network of satellites that transmit signals, which are then received by a device on Earth. By calculating the time it takes for these signals to arrive from multiple satellites, the device can triangulate its precise position.

Beyond satellite-based systems, other positioning technologies exist. Inertial navigation systems (INS) use accelerometers and gyroscopes to track movement and orientation without external signals, often used in conjunction with GNSS to improve accuracy, especially in areas where satellite reception is poor, such as tunnels or urban canyons. Radio-based positioning systems, such as Wi-Fi positioning and cellular triangulation, use the strength and location of wireless signals to estimate a device's position, commonly employed in indoor environments or for broad location services. Magnetic positioning systems can also be utilized, leveraging the Earth's magnetic field or artificially generated magnetic fields for localized positioning. The choice of system depends on factors like required accuracy, cost, availability of infrastructure, and the operational environment.
