GPS Precautions

(1) When flying in a new location for the first time, the GPS will perform a cold start, which means satellite acquisition may take longer (2–5 minutes). In subsequent flights, the GPS will perform a hot start, significantly reducing the time needed to acquire satellites (1–10 seconds).

(2) Digital video transmitters, especially the DJI O3 Air Unit, may interfere with satellite acquisition. This is because the O3 antenna can generate interference when operating. Try adjusting or repositioning the O3 antenna to prevent signal blockage directly above the GPS module.

(3) If the number of GPS satellites is still not available for a long time, you can try unplugging the power supply of O3, then power on the drone normally. When GPS satellites are detected, plug in the O3 cable. After satellites are detected, the subsequent GPS functions will not be affected. Alternatively, use USB 5V power supply until the satellites are locked, and then power on the drone.
