Hi Mike I'm just guessing, but I would confidently estimate that the landed cost of an ASH31mi plus trailer, tow out gear etc would be in excess of $250K. I am happy for Bernard to correct me here. So more more money than sense doesn't really apply in this case. As a matter of interest the

Matthew, No, it would not. Try Clearnav or I think, most of the other dedicated glider moving map instruments, and you can zero in to a point with accuracy of better than 500M. Regards Bob Ward -Original Message- From: Matthew Scutter Sent: Sunday, March 24, 2013 3:32 PM To:

I've seen warnings regarding putting two GPS units close together than 300mm. Certainly, I have seen interference between a Flarm and GPS in my glider. Does this hold valid and does the situation change with different frequencies used by alternate GPS systems? D

The problem isn't the GPS frequencies as they are receivers. However they have local oscillators and are digital devices so can create electromagnetic interference which can overwhelm the front end of a GPS receiver rather easily. GPS signals are very weak, below background noise. Easy to
