In this paper, a method for determination of developable spherical orthotomic ruled surfaces is1given by using dual vector calculus inR3spherical orthotomic spacelike and timelike ruled surface generated by a curve on dual Lorentzianunit sphere can be obtained from coordinates and the first derivatives of the base curve. The paperconcludes with an example related to this method
