GPShöjdmätare
GPShöjdmätare translates to GPS altimeter or GPS height meter. It is a device or system that uses the Global Positioning System (GPS) to determine an object's altitude above a reference surface, typically mean sea level. Unlike barometric altimeters which measure atmospheric pressure, GPS height meters rely on the signals transmitted by GPS satellites.
The principle of operation involves calculating the distance from the GPS receiver to multiple satellites whose
To improve accuracy, many GPShöjdmätare systems employ techniques like differential GPS (DGPS) or Real-Time Kinematic (RTK)
