Unobstructed to horizon for 180deg, other 180deg is about 60deg above horizon I had to wait around 2-3 hours for several days to get a fix on mine (My neo was placed near the window for a couple of days). Apparently only the first ever fix took a long time atleast in my case. After that getting a fix should not be a problem.

Re: Never getting GPS lock
I seem to have got it working, although I’m not too sure how. It finally got a fix when I was inside playing around with different gllin options. I tried the cold option (cold start) and then “-sim“ (not using simulator) 5min after that it was getting fixes. Although I can't be sure the different options had anything to do with getting it to work and I have no idea why it would have been using the ‘simulator’ in the first place since I was using a normal buildhost image and standard gllin ipk In any case, it's working now so i'm happy :) Thanks for your help Ben.
