US Patent 11047989 GNSS device

Usability of a GNSS device with a tilt sensor is improved. A GNSS device includes a tilt sensor capable of measuring a tilt, an electronic compass capable of measuring a direction, a GNSS antenna capable of acquiring positional information, and a display unit capable of displaying information, wherein when the tilt sensor or the electronic compass requests calibration for adjustment, an icon calling attention is displayed on a screen of the display unit, and when the icon is tapped by a user, the screen of the display unit shifts to a calibration screen. When calibration is required, immediate shifting to a calibration screen is enabled, so that high operability and usability are obtained.
