Select UltraTrac to record track points and sensor data less frequently (UltraTrac, page 78).
NOTE: Using GPS and another satellite together can reduce battery life more quickly than using GPS only
(GPS and Other Satellite Systems, page 78).
GPS and Other Satellite Systems
Using GPS and another satellite system together offers increased performance in challenging environments
and faster position acquisition than using GPS only. However, using multiple systems can reduce battery life
more quickly than using GPS only.
Your device can use these Global Navigation Satellite Systems (GNSS).
GPS: A satellite constellation built by the United States.
GLONASS: A satellite constellation built by Russia.
GALILEO: A satellite constellation built by the European Space Agency.
UltraTrac
The UltraTrac feature is a GPS setting that records track points and sensor data less frequently. Enabling the
UltraTrac feature increases battery life but decreases the quality of recorded activities. You should use the
UltraTrac feature for activities that demand longer battery life and for which frequent sensor data updates are
less important.
