BLUEMOMENT

I'm glad the device worked for you, but I do not work by spreading doubt - - just what I've learned from being involved in marine electronics and computers for about 35 years. If we could make it cheaper we definitely would, as we started this as an enabler for the app for our TeamSurv project (www....

Yes, you can do that if you want.

NMEA is also opto-isolated on the receive si...

Or there are a few sites telling you how to make a sextant out of a spare CD, such as http://www.zetatalk3.com/docs/Navigatio ... d_2004.pdf

The maths isn't too difficult, but it is one of those things you need to repeat often enough to get into the swing of it. Or you could make life easier by using a tool like WinAstro (www.winastro.com), which saves the cost of annual tables too. For time, any digital watch is likely to be accurate en...
