Enabling Secondary Satellite Constellations
Enabling a secondary satellite constellation allows for your watch to more quickly acquire a satellite fix, and can help maintain satellite connection in degraded signal situations where the environment may be a factor. If you are experiencing issues with speed and distance due to degraded GPS signal, enabling a secondary satellite constellation may help.
Enabling Secondary Satellite Constellations
Note: Enabling a secondary satellite constellation will use additional battery power when using GPS on your watch.

Examples of Secondary Satellite Constellations
GLONASS
Short for Global Navigation Satellite System, GLONASS is a Russian satellite-based navigation system that works alongside GPS (Global Positioning System) to provide position information to compatible devices. With an additional 24 satellites to utilize, GLONASS compatible receivers can acquire satellites up to 20% faster than devices that rely on GPS alone.
Galileo
On December 15th 2016 the European Commission announced that the European satellite system Galileo will start offering its initial services. Over the next few years Galileo will increase the number of satellites from the existing 18 to the full operational capacity of 30 satellites.
