This study focuses on the processes of covert video surveillance of the trajectories of a swarm of aerial vehicles using an infocommunication network of optoelectronic stations. The addressed problem is the integral estimation of swarm positioning accuracy at each fixed time point of optical and infrared observation. The proposed method provides practically sufficient accuracy in estimating the position, shape, and boundaries of the actual area where the swarm is likely located with a given probability. A technique is presented for constructing such an area depending on the spatial relationship between the swarm and the positions of the network’s optoelectronic stations. Numerical results of the integral estimation of the positioning accuracy of a swarm of aerial vehicles – consisting of arbitrary numbers of units – are presented, depending on the numerical values of the geolocation error variances; the errors in azimuth and elevation angle estimates for each optoelectronic station; as well as the mutual spatial arrangement between each station and the swarm. The obtained results are used to improve the metrological characteristics of the infocommunication network of optoelectronic stations in the tasks of detection, tracking, and high-precision estimation of the swarm trajectory parameters.
