Hi Adam,

    Actually I already have a digital compass onboard to make bearing
corrections because the heading I got back from the GPS receiver was too
slow to update and absolutely required a displacement. So I get "current
position" and "heading to next way-point" from the GPS and "current heading"
from the digital compass. The PIC then calculates the difference and
corrects accordingly. I never thought of using the boat's navigation systems
to orient an antenna though :-) Good idea!

Regards,

Tobie
