000001847 520__ $$2eng$$aThe pan and tilt devices (P&TD) are often used for placement of camera and antenna systems which must track moving objects (targets) precisely and speedily in many applications. For the basic testing of the adjustment and the quality of their positioning servomechanisms, the unit step functions of position or velocity are used as command signals. We have developed the program SNBP for the complex testing. The algorithms description of its foregoer EFG was published in the conference Engineering Mechanics 2004. As time goes on, it has shown the necessity to develop a connecting link – the generator of only basic command signals necessary in the middle phase during servos testing. We have utilized the traditional model of a target movement, i.e. the hypothesis about its uniform straight-line motion. This model is not able to generate a correct command signal for the elevation motion control in the range greater than ± 90°. At present, P&TDs are made with substantially greater elevation ranges. Therefore we have remade completely the model. The simulation model, which we present now, is able to generate the command signal for the unlimited traverse motion and for the elevation motion, too.
