Sharing one GPS between Gluonpilot and an OSD?

Hey guys,
I was wondering if it's possible to share the NMEA output of a single GPS between gluonpilot and an eagle tree osd in particular, is it as simple as connecting the GPS's output to both units with one of them of course providing power or is it more complicated?

I guess it could be shared (never tried it however). Input towards GPS is harder to share...

Can you please be more specific? I thought GPS modules were supposed to just output a string like NEMA without expecting any input from the receiving device, isn't that the case?

Just a heads up Tom, I think the datasheet link for the LS20031 GPS module at your shop section is dead, even the one at sparkfun's website is outdated, the latest one is v1.3, it looks like a significant update.

Thanks for letting me know, I updated the link
Gluonpilot starts by setting the GPS baudrate to 115200 and selects some specific NMEA sentences to optimize the overhead. This means the gluonpilot needs to send data to the GPS module. If 2 modules need to use 1 GPS unit, then only 1 unit will be able to send commands to the GPS (unless you use additional circuitry). In your case you probably don't need input from the OSD module, so I think it will work!
