  Timing analysis of PSR J1705$-$1906 using data from Nanshan 25-m and Parkes
64-m radio telescopes, which span over fourteen years, shows that the pulsar
exhibits significant proper motion, and rotation instability. We updated the
astrometry parameters and the spin parameters of the pulsar. In order to
minimize the effect of timing irregularities on measuring its position, we
employ the Cholesky method to analyse the timing noise. We obtain the proper
motion of $-$77(3) \,mas\,yr$^{-1}$ in right ascension and $-$38(29)
\,mas\,yr$^{-1}$ in declination. The power spectrum of timing noise is analyzed
for the first time, which gives the spectral exponent $\alpha=-5.2$ for the
power-law model indicating that the fluctuations in spin frequency and
spin-down rate dominate the red noise. We detect two small glitches from this
pulsar with fractional jump in spin frequency of $\Delta
\nu/\nu\sim2.9\times10^{-10}$ around MJD~55199 and $\Delta
\nu/\nu\sim2.7\times10^{-10}$ around MJD~55953. Investigations of pulse profile
at different time segments suggest no significant changes in the pulse profiles
around the two glitches.
