The problem of optimizing the mutual spatial arrangement of receiving positions and a radio-emitting object is actual in the conduct of a radio monitoring system with a bistatic goniometer system. The method based on the concept of inverse dynamic problems is chosen as the basic method for synthesizing the control of an aerial vehicle (AV) of information support. To perform the synthesis, the choice was made of the initial dynamic model of the state of the control system, including the models of the relative motion of the information aircraft and the source of radio emission (SRE), the pilot aircraft and the SRE, and the mutual angular displacement of the two aircraft. Taking into account the generalized dynamic model of control system state, algorithms of trajectory control of informa-tion aircraft for two variants of using bistatic radio monitoring systems guaranteeing the minimization of the errors in the loca-tion of SRE are developed. The first option involves the output of an information aircraft on the perpendicular to the line of sight \"leading AV-SRE\" at a point and then flying along this perpendicular. The second option provides guidance information AV to the best orthogonal observation point, located on the perpendicular to the line of sight \"leading AV-SRE\" at a distance from the SRE at a predetermined distance. The results of the carried out mathematical simulation of the modes of guidance of an aircraft to a stationary ground-based radio-emitting object make it possible to conclude that the proposed control algorithms for information aircraft are efficient and provide a sufficiently high efficiency of the functioning of the bistatic gyro-position detection system of the SRE.
