4.17. 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 5 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).
4.18. GPS accuracy and power saving
The GPS
fix rate determines the accuracy of your track - the shorter the interval is between
fixes, the better the track accuracy is. Each GPS fix is recorded in your log when recording an
exercise.
The GPS
fix rate also directly aects battery life. By reducing GPS accuracy, you can extend
the battery life of your watch.
