ive seen lots of stuff about JetCat GPS, but can find no place to purchase. are people using this and how easy is this to impliment?

i have an EagleTree FDR and telemetry system-i am interested in putting this in a plane, but of course concerned about installing yet another EMI source (900 mHZ) in a already challanging environment.
the EagleTree has a RS 232 connection cable from ESU to the FDR. never tried it.
also, i have a really small 10mHZ GPS module from EagleTree. i use it with their little Elogger in an electric plane, but wonder if there is any way to incorporate this as a GPS source with the ESU.

any crazy thoughts on all of this?

thanks
