From memory Julien limits the number of sats to 23, and only logs NAV PVT.

That appears to be the case in the Motion files I just checked, (No NAV-Sat) but I am pretty sure he managed to do it including sat data. I thought that was the main reason why the Sat numbers were limited. I have not yet found any files that have it though from my tests.

You have to enable it in the settings file. I do not limit the number of satellites in use but exclude the poor ones which yields about 16-24 in use. More isn't helping and forces the receiver to gasp for air every once in a while.

That makes good sense Julien. no point having stuff you don't need.
