The problem of optimization of video cameras couple disposition for providing maximal precision of radius-vector and velocity vector of natural and artificial objects in atmosphere and near earth space from double-station TV observations is considered. The influence of video cameras resolution and precision of determination of the observational points positions onto the distance to atmospheric object calculation precision is investigated. The formula for calculation of relative error of the distance determination expressed in values of basic distance is derived. For determination of errors of object radius-vector and velocity vector components the modeling of direct probl em with application of Monte-Carlo method is used. 3D distribution of an error for the observed object coordinates calculation is shown. The calculation precision for velocity absolute value of a body, and error distribution for velocity vector direction of a sphere is demonstrated. For demonstration the calculation results of atmospheric parameters of meteors are used. Possible fields of obtained results application are briefly discussed: astronomy, geophysics, physics of atmosphere, geodesy, aviation, computer vision systems.
