+I tested initially with an EM-405A GPS (This is a 5Hz, 5V GPS, and therefore I
 also needed a voltage divider to make the received data compatible with the
 Flymaple 3.3V GPS input on pin D0).  This GPS was unsatisfactory due to long
 time lags in changing ground track and speed, and also due to large random
 ground speeds up to 1.0 m/s when stationary. I was able to get ok behaviour

 I also tested with a Eagle Tree GPS$v, which is a 10Hz, 3.3V GPS board
