Hi,
This message is directed towards Curt and David Megginson.
I sent my changes to the GPS instrument module, first to Curt and then to
David, but I'm beginning to wonder if any of you ever got my e-mail. I've
not heard anything and AFAICT they have not been committed.
Am I being ignored? I

No -- apologies. I typically juggle 30-100 active items in my INBOX, aside
from the 500-1000 spams I receive every day. Patches, bug

The big difference is that GPS accuracy remains roughly constant during any
specific approach,

Yes this makes a difference but DGPS or WAAS is *MUCH*

I've added some more funtionality to the GPS module (gps.cxx). I can
define a waypoint as lon and lat values, or I can input the waypoint ID
(this currently only works for airport IDs). Now the distance, bearing and

My guess is that gpsd would just work if setup
