The problem of increasing the accuracy at estimating the inertial navigation systems errors by using identifying the parameters of the model is investigated. A scheme for correcting navigation systems with an estimation algorithm is presented. The accuracy of the errors estimation for the inertial navigation system by using the nonstationary adaptive Kalman filter when the average frequency of the gyroscope random drift changes is determined. A simple method for parametric identification of the change average frequency of a random drift by using a tuning coefficient is proposed. The results analysis of the estimation algorithm modeling by using the data of laboratory experiments with the serial navigation system Ts-060K is carried out.

The problem of formation of a quadrocopter control, which ensures the trajectory safety of its movement within the boundaries of urban development, is considered. To test the control, a simulation model is used, which includes a mathematical model of a quadrocopter, an algorithm for forming an urban environment, an algorithm of a measuring system operation based on a complex of laser range finders. The control is formed on the basis of this system measurements, taking into account the given levels of safety, each of which corresponds to a given distance interval of the quadrocopter from an obstacle, and taking into account its angular position. The simulation results show the fundamental applicability of the considered approach to the formation of a quadrocopter control that ensures trajectory safety.

A method for predicting the trajectory of an unmanned vehicle using graphs and a network of long short-term memory (LSTM) is developed. The learning model of LSTM network uses an encoder and decoder structure. Based on the graph and the attention mechanism, the encoder encodes information about the received trajectory to form a feature vector, which is puted to the decoder to predict future trajectories. To cope with multimodality in predicting vehicle maneuvers, module of convolutional network (CNN) is used. These two networks: LSTM and CNN are integrated for multimodal trajectory prediction.

The issues of cooling control automation for an internal combustion engine (ICE) of cars and trucks are considered. An algorithm for controlling the number of revolutions of the electric motors for the liquid pump and the radiator fan, depending on the temperature of the internal combustion engine coolant is proposed. This algorithm is stir up by the Arduino MEGA 2500 microcontroller in conjunction with the motor driver.
