By using them in common view, though, any absolute error would drop
out.  I'm not sure pulsar pulses are fast enough to do discrimination
at 30 ns time scales, though.  VLBI with broadband sources (quasars)
would be fine here, but large amounts of data would need to be
exchanged, and the sources are weak, requiring large antennas.

Satellite laser ranging using LAGEOS and friends?  But the original
poster said no satellites (not even passive rocks in MEO?), and
weather is a problem.
