I think the radio elescope(s) needed are much smaller. There are apparently 2 pulsar
clocks installed here in europe, one in St Catherine's church Gdansk and the other in the
European Parliament, Brussels. The Wiki article states "The pulsar clock consists of
a radiotelescope with 16 antennas, which receive signals from six designated pulsars.
Digital processing of the pulsar signals is done by an FPGA device" . I have tried
to find more details without success, but the antennas must be reasonable sized to be
installed in such places. I think the OP link indicates that X-ray wavelengths would be
used which bring down the detector size. No use on earth though.
It would be interesting to find out more info.
Xrays are nice (see X-NAV), but so far, nobody has built a small,
lightweight X-ray detector of sufficient efficiency. You don't want to
have multiple detectors the size of Chandra, XMM, or Nustar
