3.16. FusedSpeed
FusedSpeedTM is a unique combination of GPS and wrist acceleration sensor readings for
measuring your running speed more accurately. The GPS signal is adaptively filtered based
on wrist acceleration, giving more accurate readings at steady running speeds and a quicker
responses to changes in speed.
FusedSpeed benefits you the most when you need highly reactive speed readings during
training, for example, when running on uneven terrain or during interval training. If you
temporarily lose the GPS signal, for example, Suunto 9 is able to continue showing accurate
speed readings with the help of the GPS calibrated accelerometer.
TIP: To get the most accurate readings with FusedSpeed, only glance shortly at the
watch when needed. Holding the watch in front of you without moving it reduces the
accuracy.
FusedSpeed is automatically enabled for running and other similar types of activities, such as
orienteering, floor ball and football (soccer).
3.17. FusedTrack
To save battery when exercising, some of the battery modes in Suunto 9 change the interval
of the GPS readings. To avoid getting bad GPS tracking when exercising Suunto 9 uses
FusedTrack. FusedTrack uses motion sensors to log your movement between the different
GPS readings, which will provide better tracking of your exercise.
