I don't think there is any direct claim for this. But you will find lots of old research about optical flow measurement for navigation. Optical flow sensor part of https://en.wikipedia.org/wiki/Optical_flow https://en.wikipedia.org/wiki/Optical_flow seems like a good start.

Every plane already has GNSS receivers, so implementing RNAV is basically a software feature.
