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 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).
3.15. 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.
To toggle GLONASS on/off:
1. Select a sport mode that uses GPS.
2. Open the options menu and scroll down until you reach GLONASS.
3. Press the middle button to toggle the setting on or off.
NOTE: The GLONASS setting is a global setting. When you enable it, GLONASS is
activated for all sport modes with GPS.
3.16. 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 affects battery life. By reducing GPS accuracy, you can extend
the battery life of your watch.
The GPS accuracy options are:
•
Best: ~ 1 sec fix rate with full power
•
Good: ~ 1 sec fix rate with low power
