The article describes simulation modelling research for accuracy of light source angular point calculation based on intensity distribution on the photodetector array surface. Simulation uses noise, vibration of send and receive optical channels. We analyzed the influence of statistical values of photodetector elements position on the accuracy of laser light source azimuth and spot calculation. Using χ2 criteria we estimated the convergence of angular point positions density to Gaussian distribution with parameters based on statistical means and dispersion calculated from statistical aggregate. Received statistical characteristics can be used to validate the requirements for photorecevier resolution.
