Gps Accuracy And Power Saving - Suunto SPARTAN ULTRA 1.4 User Manual

3.11 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
•
OK: ~ 60 sec fix rate with full power
•
When set to Best, your watch is using GPS at full power all the time.
In full power mode, the GPS is able to filter out interference and
get the best fix. This results in the best track accuracy, but also use
the battery the most.
By using Good, you can still get GPS fix every second, but the
accuracy is reduced because the GPS is not in full power mode all
the time. Between fixes, the GPS goes into a low power mode for a
short time, as illustrated below.
