Suunto Spartan Sport Wrist HR

3.15. 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 Spartan Sport Wrist HR 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).

3.16. GLONASS

GLONASS (Global Navigation Satellite System) is an alternative positioning system to GPS.
With GLONASS enabled, your watch may record a more accurate track in certain conditions.
Particularly in urban areas with tall buildings, GLONASS can improve track accuracy. In other
areas, it is typically best to leave GLONASS disabled. With GLONASS enabled, your watch
consumes more battery life.
