Position 5.769067°N 10.807782°E Timestamp Sat, 7 Jan 2017 18:34:27 UTC Close to Foumban, Cameroon Local time Sat, 7 Jan 2017 19:34:27 WAT Timezone Africa/Douala (UTC +0100)

Expected: (i think) somewhere in Germany.

Hey Lasse, yes it should be somewhere in north Germany.

Correct Position should be 54° 61.44’N 10° 48,46’E It seems that the fault is a shifting digit from degrees to minute

I think i have to sail ca 300Nm with course north to come in your Sailing area :-)

I think 352df6b22c1d8cc5ea96601f5fe541a1bf2e4871 fixed this, but I need the original failing input to validate. Can you take a look, @leifnagtegaal ?

ProfAronnax commented 7 years ago

serialdump.fdx.txt i pulled your last commit in your rep, but i am still in Cameroon

lkarsten commented 7 years ago

Hi. Thanks for the sample data.

I've added another patch now, which puts you firmly in Germany at least in my testing. If you have the time, further testing would be very much welcome. @leifnagtegaal

ProfAronnax commented 7 years ago

Jippieh, now is my position fix correct

lkarsten commented 7 years ago

@leifnagtegaal thanks! :-)
