3.13 FusedAlti
FusedAlti TM provides an altitude reading that is a combination of
GPS and barometric altitude. It minimizes the effect of temporary
and offset errors in the final altitude reading.
NOTE: By default, altitude is measured with FusedAlti during
exercises that use GPS and during navigation. When GPS is switched
off, altitude is measured with the barometric sensor.
If you do not want to use FusedAlti in altitude measurement, you
can disable it in the options menu.
