Well it sort of works, I'm having trouble testing as I need to use a Windows machine to run u-center, and my main machine is not Windows. It is also very bright outside and the screen is not.
Nevertheless I've tried running it in a single position (ie leave it on the ground) and get the drift within a 1.5m x 1m box on the edge of an oval. It does appear to work and switches to Differential Mode rather than Autonomous. Key things I've found out are the satellite is at an elevation of 49 degrees and an Azimuth of 9 degrees (from Adelaide) and C/NO 42. You have to manually set the PRN code to 122 to use only the Australian SBAS. You need to turn Galileo off as there are no corrections for it (on L1) and just use GPS and GLONASS. In the SBAS menu you must turn on "allow test mode use Msg 0". It was recommended to turn off Ranging. Things specific to my setup are you need to save the configuration to the Flash memory otherwise you have to reconfigure each time you plug it in (CFG Menu). In the config it was recommended to me to set in the NAV5 menu an appropriate Dynamic Model, I'm using "Stationary". I lose the SBAS each time an aircraft passes between me and the SBAS satellite. Running it indoors (concrete tiles, brick walls) for about twenty minutes stayed in a 10m x 10m box. The next step is to get it running under OSX and be able to detect it is in Differential mode, and try visiting some survey marks sometime next week.
