SIMPLIFIED DYNAMIC MODEL OF THE TRANSMISSION

Abstract eng:
Within the framework of the grant project FT–TA3/103 of Ministry of Industry and Trade of the Czech Republic, the prototype of the passive optoelectronic rangefinder (POERF) is developed. A number of subsystems of this rangefinder needs to be solved in this connection. One of these subsystems is the transmission – usually with the same construction for the gearing in the elevation and in the traverse. The accuracy of the measured target coordinates depends both on the accuracy of the measured target range and on the accuracy of the measured target angle coordinates which are taken relatively towards the rangefinder position. The mathematical model of the rangefinder aiming system (special positional servomechanism) is published in Čech (2006). The dynamic model of the transmission is one of its important parts. The corresponding sub model is described in this paper. It makes possible the accuracy analysis of the acquisition process of the target angle coordinates.
