Arduino + GPS Data Logger

V0.1 – (done)

  • GPS -measures at 1Hz to within 5m
    • Position
    • Vg – ground velocity
    • time stamp

V1.0

logs:

  • Arduino
    • Vs – boat speed
    • Va – apparent wind velocity
    • Ba – Apparent wind angle (without correction)
    • time stamp
  • GPS
    • Position
    • Vg – ground velocity
    • time stamp

V2.0

Logs:

  • Arduino
    • Vs – boat speed
    • Va – apparent wind velocity
    • Ba – Apparent wind angle (without correction)
    • Ta – Apparent wind angle wi
    • Phi – Heel angle
    • C – course of the boat
  • GPS
    • Position
    • Vg – ground velocity
    • time stamp

V3.0

sends data to a computer via xBees

  • Arduino
    • Vs – boat speed
    • Va – apparent wind velocity
    • Ba – Apparent wind angle (without correction)
    • Ta – Apparent wind angle wi
    • Phi – Heel angle
    • C – course of the boat
  • GPS
    • Position
    • Vg – ground velocity
    • time stamp

The GPS is a bluetooth Data Logger BT-335. The control program for MAC is available here. I’ll get the sensors working and calibrated and a code worked out on the Arduino with a data logger first. Then start adding things.
I have been asked why I don’t just use a GPS directly plugged into the Arduino. This definately would be a better solution to use the GPS logger shield. But because I’d like to keep it VERY simple at first and I’m on a small budget, I’ve chosen this path.
