GPS Denied navigation

Cube Autopilot

Hi is there an optical flow navigation solution for CubePilot in GPS-denied environments? I see here Flow is good for position hold but what about navigation, where GPS is not available?

Thanks

Mark.

Hello,
there are propertary camera-based system, other based on external IR/RF beacons, and some like the ones we develop, that doesn’t require any external beacon, and can work at night.
All depends on the precision you need to achieve, and flight characteristics (altitude, speed, etc).
And then there are some defense-grade solution that you won’t really find out in the public…
