Greetings, It's been a while, but I see things are picking up again on this thread.
Looks like Don laid out the procedure very well. About the only difference is that I leave stellarium running, and consider the small differences as the randomization that was talked about earlier in the thread. My readings are a minute or 2 apart, and at 9 kts the sub would only move .9 NM.
Also, I record the ALT and time, with both clicking away I sometimes get a little error from this, which I chalk up to rough seas. Just got a new computer and its been fun getting things running again. Mike.
