Kohasüsteemid

Kohasüsteemid, known in English as location systems or positioning systems, are technologies that determine the geographical position of an object or person. These systems are fundamental to a wide range of modern applications, from navigation and mapping to logistics and emergency services.

The most prevalent kohasüsteem is the Global Positioning System (GPS), which relies on a network of satellites orbiting the Earth. A receiver on the ground listens for signals from multiple satellites. By measuring the time it takes for these signals to arrive, the receiver can triangulate its position with high accuracy. Other global navigation satellite systems (GNSS) exist, such as Russia's GLONASS, Europe's Galileo, and China's BeiDou, offering similar functionality.

Beyond satellite-based systems, other kohasüsteemid utilize different principles. Indoor positioning systems, for instance, often employ Wi-Fi triangulation, Bluetooth beacons, or ultra-wideband technology to provide location data within buildings where satellite signals are weak or unavailable. Cellular triangulation, which uses cell tower signals, is another method, though typically less precise than GPS.

The data generated by kohasüsteemid is crucial for services like ride-sharing apps, fleet management, geographical surveys, and even personal fitness tracking. The continuous advancement in this field promises even greater accuracy and a wider array of applications in the future.
