Difference beetwen CTUN.SAlt and RFND.Dist

Hi, I would like to understand what SAlt is, regarding to RFND.dist measures ? Is it derived from Rangefinder measured distance taking attitude into account ? Sometimes I have more than 30cm difference. Thanks

RFND.dist gives what the rangefinder reads, whereas SAlt is rangefinder value adjusted to roll and pitch angles

Hi, thanks a lot. This replies to a long running question :slight_smile: As you seem to be well skilled regarding rangefinder feature, could you take a look at this other post I did ? : Does ArduPlane take care of Lidar angle when landing?
