Mine updates 5 times a sec... some update even faster. I am and Electrical Engineer
and I am developing an autopilot as a hobby. I am trying to get away from using a compass
(as most commercial
autopilots do). A second is too slow of an update if I want to try using GPS data alone as my only input to my autopilot. This would most likely lead to bad oscillations at the rudder
There are other ways around this. I could do the crosstrack error calculations in my microprocessor but I like the OpenCPN
gui interface and it would start getting messy if I do it that way. I want it to do more than just follow a course. I want it to go from waypoint to waypoint.
I have done some research
on entry level autopilots, but not alot. I would appreciate any suggestions on my approach.
I would really appreciate it if you would add this feature but since you would only be doing it for me I understand if you don't.
