The GPS Signal Unavailable pop-up warning message indicates that the GPS signal is too weak for Dronelink to take control. A stronger GPS signal is required to successfully engage the mission and can be achieved the following way:
- Wait for a stronger GPS signal, especially if the drone was just powered on
- Move or fly the drone to a more open area to get a stronger GPS signal
- Fly to an area with less interference to get a stronger GPS signal
- If using RTK, ensure that RTK is enabled correctly in the RTK settings. Learn more here. The RTK positioning solution must at least be Fixed Point or Float. Otherwise disable RTK positioning completely.
