Brad,

Like Paul mentioned, sharing a GPS engine between two device is a common "Poor Man's" navigation solution. For several years I have been driving both an EW Model D flight recorder and Compaq Aero 1550 with a Garmin 12xl.

Any FAI acceptable GPS unit can be substituted for the Garmin 12xl. The Goddard SPS-1 is a good power and device connection solution.

Hi Brad,

I'm sorry, but I don't think that is possible.

It is possible to have a GPS send NMEA data to 2 soaring instruments or
PDAs. But each GPS engine needs its own antenna. I don't think a single
GPS antenna can be connected to 2 different GPS units - which is what I
think you are trying to do.

Good Soaring,

I would like to use a GPS antenna that I could send NMEA data to both
my Glide Computer and my PDA running flight sortware.

Any thoughts on how something like that would be wired up?

I have a Gilsson antenna with a brass plug that fits into my iPAQ 310,
if that same unit would work, I would get another one, cut the plug
off and find the NMEA send wire, of course having the schematic would
help too.
