Sounds like a fun project. Please keep me up to date on your radio and UAT development! I don't see how the GPS addition of L5 is an issue though?
The issue is the L5 GNSS is up but there are no GPS units to buy, that is the issue. Neither NavStpark or U-blox are building anything, we will be stuck with the three biggies at >$500 for a GPS...

did that been there: mini-max with Rotax 503 thermocouple CHT & EGT, fuel pressure/level/flow, RPM, intake air temperature, cabin temperature, cabin air pressure, navigational lighting control. All the engine transducers live in the engine compartment (ECC), the information from the ECC rides on shielded Ethernet, the instrumentation, navigation, lighting and autopilot controllers are connected to that dual ring SE net. Most sensors are daisy chained together in current mode over shielded cable, one wire with a redundant second cable. I ran into a show stopper on the Radio, that 80 year old AM piece of junk 700 channel radio that is so past it's time.... Working on that now, receiver that can receive and transmit on 4 channels at the same time, can receive/transmit UAT 978. The GPS issue: "A third civil signal, located at 1176.45 MHz (L5), will be provided initially on GPS Block IIF satellites beginning in 2010, and continuing with the Block III satellites scheduled for launch beginning in November 2016. This new L5 signal is protected worldwide for aeronautical radionavigation use, and will support aviation safety-of-life applications. The addition of L5 will make GPS a more robust radionavigation service for many aviation applications, as well as all ground-based users (maritime, railways, surface, shipping, agriculture, recreation, etc.). L5 benefits include precision approach navigation worldwide, increased availability of precision navigation operations in certain areas of the world, and improved interference mitigation." is an issue until we throw the FCC and vendors out. https://goo.gl/Lp7KVD more obsolete technology thanks to the people are are still thinking in pre-wwII mind set.
