Formulation of the problem. Currently, UAVs are solving a wide range of tasks, including combat and special ones. The local nature of most modern armed conflicts imposes severe restrictions on the accuracy of the use of aircraft weapons, especially in urban areas and the presence of civilians. The most high-precision navigation equipment is the equipment of GNSS consumers. An increase in the accuracy of the use of aircraft weapons, target reconnaissance and their illumination is possible through the use of estimates of the location of the equipment of GNSS consumers when solving these problems.

Purpose. Determination of the dependence of the accuracy and convergence time of the algorithm, which implements the integral rangefinder method for determining the coordinates of ground objects, on the number of unmanned aerial vehicles for various reconnaissance ranges (from UAVs to ground reconnaissance objects).

Results. An algorithm for determining the coordinates of ground objects based on measurements of a laser rangefinder-target designator and estimates of navigation equipment of GNSS consumers has been synthesized. Graphical dependences of errors in determining the coordinates of ground objects for goniometric-ranging and integral ranging methods are obtained. Their comparative analysis is carried out. The mathematical basis of the synthesized algorithm is the maximum likelihood method.

Practical significance. The data obtained as a result of modeling allows us to recommend a synthesized algorithm for determining the coordinates of ground objects for practical use on modern UAVs, since it allows achieving a higher accuracy of target reconnaissance.
