Thanks for the links, I didn't see the 2015 test.  Currently the older
Spirent simulators are going for very resonable prices on the 'bay.
The GSS4100 can be had for under $200 and 6100s frequently pop up for
$150.  Anything newer is still very expensive, though. It may be
necessary to use a multichannel simulator for newer receivers (or
multiple synchronized single channel units), as I haven't yet been
able to get the Trimble Resolution boards to go into overdetermined
mode with a single simulated SV.
