Sensor: Location (GPS)
The experiment "Location (GPS)" just gives the raw data from the phone's location services. Usually, this should be the data from the GPS, but on iOS we cannot prevent the system from using location data from the mobile and WIFI networks as well.
The raw data consists of location and height information. Additionally, the system derives a speed and direction from consecutive GPS fixes. Finally, phyphox also gives status information, such as accuracy and number of satellites. However, not all information is available on all platforms.
