The research of the nonexcluded air control error componentin optoelectronic systems the spatial position of distant objects control based on dispersion method is provided. It is invited to consider the influence of the air tract on the direction of an optical beam. There is some methods of the nonexcluded air control error component determination in the paper.

Continuous development of high-speed railway traffic in the world toughens requirements, including to the accuracy of installation and control of provision of a railway track. For the current technologies of service of a railway track using its absolute coordinates the perspective decision is creation along railway lines of a special fiducial network. In this case by means of optical-electronic systems, concerning reference points, obtaining the objective information on actual position of a railway track in a longitudinal cross-section and the plan with a margin error which isn't exceeding 1,5 mm in rather severe conditions of continuous operation of traveling machines at speeds up to 10 km/h is possible.
Development of robotic vehicles allowed to carry out massively introduction of their different spheres of activity. But often a necessary condition for the functioning of such systems is the presence of the control of their movement. The opto-electronic system control the spatial position of vehicles, such as mobile robots, describes in this paper. The system consists of reference marks installed on the vehicle and cameras for watching it. The paper presents a mathematical description of the system, the method of determining the coordinates of objects based on their photographic projections using the camcorder. The layout system was developed for testing algorithms having two cameras observe the movement of the layout of the vehicle, realized on the platform Rover 5 Chaisis. The reference mark, which consists of four LEDs, was fixed on the vehicle. The configuration of the LEDs has been presented in the form of vertices of the cube. In the course of the study was found that error does not exceed a value of 1 mm at the distance of 2 meters.
