A modular laser level determination system includes a laser beam generator in a housing, fixed to a positioner. The laser beam is oriented towards a central shaft inside the housing that is not closed off by any obstacles and passes through a collimator. A rotation drive module of an optical assembly comprises at least one reflection plane. The rotation drive module extends in a direction coaxial with the center line of the laser beam. The rotation drive module comprises a brushless motor with electronic switching, a hollow shaft, and a stator fixed to an element fixed in rotation. The stator can be tilted by a module for determination and adjustment of the inclination with respect to a reference place. The laser beam generator is fixed to the brushless motor.
