Hi Gary / All,
Just catching up on this thread after an enforced absence this afternoon. As the guys have said above, your Home Screen shows only 3 satellites in use - which is insufficient to achieve a GPS fix. Without a solid fix, PilotAware won't transmit and obviously can't pass location data to the Nav system or your transponder.
I appreciate that the unit had only been running for 5 minutes when you took the screenshot, but from pictures you posted previously in an earlier thread (relevant one copied below), I recall that you are (or at least were) using a standard PilotAware GPS Mouse, located up under the front edge of the coaming on the engine side of the firewall. I remember thinking at the time that that didn't look like the ideal position to ensure a good view of the sky for reception of satellites as it must presumably be under the metal skin of the aircraft (unless the panels in this area are fibreglass?). I can certainly see fibreglass underneath the mouse, but it's what's on top, between it and the sky, that is important here. I appreciate that you have been using PilotAware with the GPS in that same location for some time, but I feel this may (at least in part) be contributory to your current issues. I am no expert on Eurostar construction, however, so I would certainly recommend seeking a second opinion from the likes of Paul Kiddell (or others) via the Eurostar Forum. If you do, please let us know what they say.
Best Regards
Peter
