How accurate is the GNSS/GPS?Updated a year ago

The intelligent algorithm automatically detects how high the resolution needs to be in order to function. For certain functions that require higher resolution and clocking, the watch uses all three GNSS systems simultaneously, increasing the resolution rate to over 10 Hz (10 times per second). For activities that require fewer data points (such as hiking), the system switches to a low-power endurance mode and uses fewer satellites simultaneously, reducing the resolution rate.
