We are in August 2023, and the Ingenuity helicopter still flies over
Mars. There's no GPS satellite system on the planet, and a very little
atmosphere compared to Earth, but it is localizing itself with a
grey-scale camera that points to the ground, and it works like that...

Here is a video <https://www.youtube.com/watch?v=TP_ojUa6XtU>

The image processing computations are obtained from interpolation
performed at <https://twitter.com/stim3on/status/1419414689998594051>

transmitted down the JPL/NASA Laboratory at Caltech University...

Best regards,
