GPS Settings

You can change the GPS settings to customize the
satellite systems used for each activity. For more
information about satellite systems, go to

Life Information, page 49).
Hold UP, select Activities & Apps, select an activity,
select the activity settings, and select GPS.
NOTE: These settings are not available for all activities.
Off: Disables satellite systems for the activity.
GPS Only: Enables the GPS satellite system.
All Systems: Enables multiple satellite systems. Using
multiple satellite systems together offers increased
performance in challenging environments and
faster position acquisition than using GPS only.
All + Multi-Band: Enables multiple satellite systems
on multiple frequency bands. Multi-band systems
use multiple frequency bands and allow for more
consistent track logs, improved positioning,
improved multi- path errors, and fewer atmospheric
errors when using the watch in challenging
environments.
UltraTrac: 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.
