The effect of gyroscopic precession in Sen spacetime is investigated using Frenet-Serret formalism,and general precession formulas for circular orbits with arbi trary constant angular speed are deduced.The precession angle on the equatiorial plane and along the circular geodesics can be obtained easily from the general formulas.The effect of gyroscopic precession in static dilaton spacetime is also studied as a special case.Comparing these results with those in the Kerr-Newman and Reissner-Nordstrm spacetime respectively,we find that dilaton coupling wi ll decrease the effect of precession.
