A method for joint navigation of unmanned vehicles a group located within different physical environments is proposed. The formulation and solution of the problem regarding joint navigation of an unmanned vehicles (UV) group has been provided as follows: a model for integrating navigation information from various sources and meters to develop each device exact positioning has been provided along with an algorithm for estimating coordinates in a plane and directing a device movement with an inertial navigation system. An illustrative example has been given. A virtual training ground with terrain was proposed to simulate the navigation of autonomous unmanned vehicles (AUVs) operating within different environments.
