Advanced Navigation Boreas D90 - Wind Packet; Heave Packet; Raw Satellite Data Packet

11.4.35 Wind Packet
This packet provides the Boreas current 2D wind velocity. These values are only valid when external air data is
provided to Boreas. This can be either through the 11.4.40 External Air Data Packet or when a pitot tube is
interfaced to one of the GPIO pins. When this packet is written to the device, it disables the wind estimation filter
and the wind values provided are used statically.
