Sat., June 11, 2022 – Marine GPS on a Pi

Dave will share his work in running Marine Navigation on a Pi including:

  • hardware requirements
  • how the zero could be used, but there are drawbacks
  • I was unable to get a pi 4
  • at George’s suggestion, I decided to go with the pi 400
  • hardware modifications to integrate the GPS unit within the pi 400 case
  • introduction to and a brief overview of the OpenCPN Chart Plotter Navigation software
  • some ideas I have to make a more “system-critical” GPS solution (will implement if I have time)
