Respond safely to weak or lost GPS on a DJI drone
Use the app indicators, startup wait, open-sky placement, interference check, and ATTI-mode behavior to decide whether to launch, land, or request diagnosis.
Direct answer
The shortest reliable path.
Do not launch indoors or under an obstruction to test a weak GPS warning. Place the aircraft outdoors with open sky, away from buildings, trees, mountains, metal objects, high-voltage equipment, transmitters, routers, and Bluetooth devices, then allow about one to three minutes after power-on for satellite acquisition. If GPS becomes weak in flight and the aircraft enters ATTI mode, land as soon as it is safe because automatic hovering and braking may be unavailable.

Scope before steps.
DJI camera drones showing a Weak GPS signal or No GPS signal warning, yellow or red GPS state, or loss of position hold.
Satellite outages, aviation rules, compass calibration not requested by the app, collision recovery, or continuing a flight without reliable positioning.
Procedure
Do this in order.
- 01
Read the positioning state
Confirm whether the app reports weak GPS, no GPS, yellow or red GPS bars, or zero satellites, and note whether the aircraft still holds position.
- 02
Give the aircraft open sky and time
Power on in an open outdoor area and leave the aircraft stationary for about one to three minutes while it searches for GPS.
- 03
Remove environmental obstruction and interference
Move away from buildings, mountains, trees, metal objects, high-voltage towers, transmission or radar sites, cellular towers, Wi-Fi hotspots, routers, and Bluetooth devices.
- 04
Treat ATTI mode as a landing condition
If GPS becomes weak in flight and the aircraft no longer hovers or brakes normally, maintain visual control and land as soon as possible in a safe location.
Diagnostic matrix
Read the result, not the guess.
| What you see | Check next | What it means |
|---|---|---|
| GPS becomes normal only after moving outdoors | Repeat acquisition once in the same open area and confirm a stable flight-ready indication. | The original location obstructed or interfered with satellite reception. |
| The aircraft shifts horizontally and will not brake automatically | Assume degraded positioning and prioritize a controlled landing. | The aircraft may be operating in ATTI mode as described by DJI. |
| No GPS returns in several open locations | Preserve the app warning and request DJI diagnosis. | A repeatable open-sky failure is no longer explained by one obstructed site. |
Stop conditions
Know when not to keep changing things.
- Do not launch with weak or absent GPS when the flight mode or environment cannot safely tolerate drift.
- Land as soon as safely possible when position hold or automatic braking is lost.
- Send the aircraft to DJI for diagnosis when the warning persists in multiple open outdoor environments.
