I've got an Alphamantis Aerostick I'm dusting off for some "playing around". It's a pitot tube device, so shouldn't have any mechanical "low pass" action...IIRC, wind speed and yaw angle are transmitted at 4Hz on ANT+.
Maybe this is a dumb question, but how does it calculate angle? Is more than one pitot tube needed to capture direction? I thought a pitot tube only captured a linear velocity along the tube axis.
I was trying to look up the sensor Flo used, and it doesn't seem to be in production anymore. But the same company has newer more solid-state-like sensors that seem to use arrays of transducers to presumably do some vector math to calculate direction. Kind of interesting.
