  We determined the distances to nine pulsars by parallax measurements using
the NRAO Very Long Baseline Array, doubling the number of pulsars with accurate
distance measurements. Broadband phase modeling was used to calibrate the
varying dispersive effects of the ionosphere and remove the resulting phase
errors from the phase-referenced VLBI data. The resulting parallaxes have a
typical accuracy of 100 microarcseconds or better, yielding distances
measurements as accurate as 2%. We also report new proper motion measurements
of these pulsars, accurate to 0.4 mas per year or better.
