Gumstix and micro nav

[Vindication]

Just wanted to let any interested parties know:

We were discussing previously about using the xbow uNav sensor unit in combination with the gumstix linux board. I just wanted to let everyone know that I was able to get the uNav avionics program to compile for my gumstix. There was a compile error about a method called clock_nanosleep( but I changed the call to nanosleep( instead and it compiled. I was able to run it for my gumstix [using buildroot] and it executed. Of course I don't even have a uNav right now and I'm sure there are other tweaks necessary. Below is my output when running:

# ./avionics
[avionics]:datalogging is disabled
[avionics]:IP address connected to 10.1.5.201
Creating threads...
[imugps_acq]::thread[1] initiated...
open serial: unable to open /dev/tts/2 - No such file or directory

So I think this shows that the open source uNav stuff can be used with the gumstix board. This is good because I already have a gumstix board and also the gumstix is cheaper than the stargate!!

Knew you could do it. I'm trying to buy some gumstix, but I have plenty of stargates, so I'll probably stick with them.

I am working on an (ever changing) UAV autopilot project based on gumstix. So far I have reproduced the results by pascal.brisset@wanadoo.fr, and I am able to control 6 servos with a X-box controller.
(http://perso.wanadoo.fr/pascal.brisset/chromicro/doc/chromicro.html#pwm_accuracy)
At present I am making a coanda flying source (http://jlnlabs.imars.com/gfsuav/index.htm) and control it with a X-box controller through a gumstix.
Next I want to make it autonomous. For this I find uNav and the corresponding GCS the best starting point. For this I have briefly tried to compile uNav for gumstix (not very succesfull - will you share the Makefile).
I am still looking for a sensor package. Has anyone experience with phoenix from http://www.o-navi.com/products.htm ($1K).
I might go for Spark Fun IMU ($350) and GPS ($100).
