Hmm... maybe you had more GPS satellites visible today.

It works on pixhawk from what I've heard. I just had a recent success report from someone I asked to test on Linux with PX4. With my published builds you'll need to specify "-ap px4" to avoid the flip problem. Probably also need to add "-qgc" switch as that is disabled by default (not sure if PX4 setup requires it). Otherwise it should work according to their instructions (assuming they're up to date). But I haven't/can't personally try it.
