Pushing the limits of visual navigation in ultra-sparse environments

In the Ocotillo desert, we set out to push our software-only visual navigation system to the operational limit. In the process, we achieved a remarkable breakthrough: ultra-low (<100 ft AGL) flights over desert terrains with almost no identifiable features. Crucially, this entire feat was carried out running in real-time on a limited compute node with a narrow FOV camera.
