High information of electro-optical devices (EOD) in solving tasks of reconnaissance, weapon guidance, fire control, etc. defines them as independent objects. The success of the task in the course of the confrontation between the parties will be largely determined by spatial monitoring with following destruction (suppression) of these objects. This circumstance necessitates the improvement`s the devices of coordinate geometry of the EOD in their active and passive location. Development of a model of a quasi-single position sensor of determination the spatial position of a laser beam (LB) and determining the conditions for increasing the accuracy of coordinate measuring. Model of a quasi-single position sensor of determination the spatial position of a laser beam (LB) which includes two coordinate-sensitive matrix photo-receiving devices (MPRD) are located in the same plane at a minimum distance from each other is developed. Analytical expressions of determination`s coordinates of position of the laser beam (LB) based on stereo measurements by the sensor and the preset parameters` of focal distance of objectives, the sizes and number`s sensing elements of matrix are obtained. The error of coordinates by a quasi-single position sensor depending on the distance of the laser beam (LB) is analyzed. It is shown that for short ranges, the permissible measurement error can be achieved by measuring the parallax with one row of the MPRD`s` matrix, for long ranges, the permissible error of the parallax value is achieved by increasing the rows of the matrix`s MPRD, involving in the measurement.

A Model of a quasi-single position sensors of determination the spatial position of a laser beam is proposed and the main analytical relations that determine its functioning in the mode of determination`s coordinates of position of the laser beam (LB) are obtained.
