GPS Weak Signal
Autel Robotics Drone
Severity: ModerateWhat Does This Error Mean?
GPS Weak Signal means the EVO cannot acquire enough satellites for position-hold and return-to-home functions. Fly in an open area away from buildings, wait for the satellite count to reach 10+, and avoid flying near GPS-jamming sites.
Affected Models
- Autel EVO Nano
- Autel EVO Nano+
- Autel EVO Lite
- Autel EVO Lite+
- Autel EVO Max 4T
Common Causes
- Flying in a dense urban area with buildings blocking the sky view
- Flying near GPS jamming or spoofing sources
- Obstructed sky view from trees or structures
- Cold start — GPS takes longer to acquire satellites after being off for days
- Interference from nearby radio transmitters
How to Fix It
-
Move to an open area with a clear view of the sky.
GPS signals come from satellites above — any obstruction (roof, trees, tall buildings) reduces signal strength. A flat open field gives the fastest and most accurate GPS fix.
-
Wait for the satellite count to reach at least 10 before flying.
The satellite count is shown in the top bar of the Autel Sky app. Patience during this wait prevents mid-flight GPS failures.
-
Set your home point manually before flying in a marginal GPS area.
In Autel Sky: tap the map icon and set a home point. This ensures return-to-home works even if the drone's GPS fix was marginal at takeoff.
-
Switch to ATTI mode if GPS is unavailable and flight is needed.
In ATTI (Attitude) mode, the drone uses its barometer and IMU only — no GPS position hold. ATTI mode requires skilled piloting as the drone will drift with the wind.
Frequently Asked Questions
How many satellites does an Autel EVO need to fly safely?
The EVO Nano and Lite require a minimum of 6 satellites to take off, but 10 or more is recommended for accurate position hold and reliable return-to-home.
Why is GPS signal always weak in my neighbourhood?
GPS jamming near government buildings, airports, and military sites is increasingly common. Check local reports or apps like GPSJam.org to see if jamming has been reported in your area.
