  We have monitored 41 Be/X-ray binary systems in the Small Magellanic Cloud
over ~9 years using PCA-RXTE data from a weekly survey program. The resulting
light curves were analysed in search of orbital modulations with the result
that 10 known orbital ephemerides were confirmed and refined, while 10 new ones
where determined. A large number of X-ray orbital profiles are presented for
the first time, showing similar characteristics over a wide range of orbital
periods. Lastly, three pulsars: SXP46.4, SXP89.0 and SXP165 were found to be
misidentifications of SXP46.6, SXP91.1 and SXP169, respectively.
