For Rob, I would suggest that each TX have a GPS/PPS reference with sky 
view, and that each PC was identical (e.g. all Raspberry Pi cards), and 
then getting them synced to with 12 microseconds should be easy.  I 
achieve this even with indoor GPS puck antennas:


on six RPis, with only the occasional glitch caused by signal drop-out. 
  A better located antenna would prevent that.
