The atmospheric pressure logger with the sea level correction automatically by using GPS height information. If you want to run background, keep logging every several hours(this mode consumes more battery). In order to obtain the sea level correction value, we use the GPS position and the temperature of weather information. It is also possible to set height and position information manually if you want to record at a pre-fixed location.
