Wind Direction Calibration

[wd40]

What effect does the wind direction calibration number have on wind direction? Is the number a plus or minus degrees?

I wonder if a dampening factor for the wind vane could be added here to compensate for fine offset wind vane overshoot?

The problem with applying software damping to the wind direction is that the very best sampling rate you can get is a period of 48 secs - the transmit rate. Since the vane turns /waggles several times a second, applying damping to a 48 sec periodic sampling is unlikely to be effective.

Yes; it's intended for situations where you discover that you didn't align it correctly.

That's effectively what the average direction calculation gives (but it also takes speed into account).

Thanks for the replies Gina and Steve.
