Not having read anything on the failure, I'm surprised they wouldn't have other range finding methods. Like LIDAR actually, just not the LIDAR everyone thinks of. They have them on commercial drone packages. It's like a single beam LIDAR setup. Does better at long distance range finding than the mmWave Radar units. The mmW unit handles water better though. The engineers that built the JP lander are likely far smarter than I am and probably thought things through much better than my simple armchair observations.
- magicalhippo 3y agoA single beam LIDAR would suffer the same problem. That is, the radar was accurate, the problem was the team hadn't foreseen the probe flying over such a deep crater, thus the threshold for failing the sensor in case of a sudden large change in apparent altitude was set too low. This is why I suggested a visual-based sensor, since it would be using a very different measuring scheme, and one which could also be used to cross-check the IMU data.
