I use PX4 v1.4.2. And GPS receiver uses Piksi(Swift Navigation).
I am challenging to incorporate Piksi's driver perfectly.
Currently, it seems that the flight controller is able to recognize the position information, but it gets out of fix periodically, causing a big error.
I think that such values are not shown in raw GPS data, so is there any need for setting?
Or simply, is my program wrong?
