Home Heading Wind Vane¶
WNDVN_TYPE = 1, the wind vane library assumes the true wind is coming from the direction the vehicle was pointing when armed. This method is slightly improved upon by using WNDVN_TYPE = 2 allowing this initial wind direction to be offset +- 45 degrees by a RC input channel defined by WNDVN_RC_IN_NO. These methods do not directly sense the wind but just assume it is coming from a constant direction so they shouldn’t be used in shifty wind conditions or for longer missions. They are however a good method to test sailing support before a proper wind vane can be fitted.
