QZSS (also known as Michibiki) is not displayed in the menu
QZSS (Quasi-Zenith Satellite System) will not be displayed in the RTK → System → Number of satellites acquired section of the Airpeak Flight app because the RTK GNSS doesn't use that correction data. In Japan, QZSS is used when positioning the base station antenna automatically or when performing GNSS (Global Navigation Satellite System) single-point positioning the aircraft antenna.
