Summary/Abstract: The straight-course of the positioned truss structure module is maintained by a laser instrument. A laser beam generator emitting a vertical beam is placed at the end of the experimental field. A laser beam catcher with photo diodes is mounted on a positioned truss structure module replaceable support. Course deviations were assessed in twice cases: when laser, straight-course maintaining mechanism was mounted at the same end of the truss beam as positioning trundle; and when it was mounted at the middle of the truss beam. Furthermore, we estimated how course deviations vary when changing interaxial distance of laser catcher photodiodes. Electromechanical transmitter was used in the tests. Truss structure module is positioned by a special positioning trundle. It is run by a 12 V electric motor through a worm self - braking reduction gear.
