📍 What “GPS” Really Means
GPS = one satellite system.
GNSS = many satellite systems (GPS + GLONASS + Galileo + BeiDou).
More satellites = better accuracy.
🌐 GNSS Explained (Simple)
Think of it like having more than one map instead of only one.
Your watch listens to multiple satellite groups to find your location faster.
🔀 Multi-Band / Dual-Frequency
This mode uses two signals at the same time.
It helps when you’re:
-
🏙️ near tall buildings
-
🌲 inside forests
-
🏞️ running near mountains
Multi-band gives cleaner, straighter GPS paths — but uses more battery.
⚙️ Auto GPS Modes
Some watches (like Garmin) choose accuracy for you.
Example:
SatIQ switches between “high accuracy” and “battery save” depending on the sky view.
🏃 When to Use Which
Use Multi-Band:
-
City runs
-
Trail running
-
Dense trees
-
Weak signal areas
Use Standard GNSS:
-
Walks
-
Open road
-
Outdoor gym
-
Clear sky
Saves hours of battery life.
🔋 Battery Tips
-
High-accuracy GPS drains faster
-
Turn on “GPS Only” for short activities
-
Turn off AOD (Always-On Display) during long runs
