A parameter / UTM beacon is a device used in the field of geographic information systems (GIS) and global positioning systems (GPS) to accurately determine and transmit location data. It is a small, lightweight device that is typically attached to a person or object and emits a unique signal that can be detected by GPS receivers. This signal contains important information such as latitude, longitude, altitude, and other parameters that help to precisely identify the location of the beacon. UTM beacons are commonly used in outdoor activities such as hiking, mountaineering, and search and rescue operations, as well as in scientific research and military operations. They play a crucial role in ensuring the safety and efficiency of navigation and mapping in remote and rugged environments.
