The paper analyzes the data transmission system based on UWB technology for unmanned surface vehicles. The main advantages of using ultra-wideband signals are presented. It is shown that such a communication system allows for a transmission speed of several tens of Mbps with a radio path length of not more than 10 m.

The article is devoted to the study of Kalman filtering errors of the measured radio navigation parameters into the coordinates and elements of the objects movement in relation to the ground-based radio navigation system of local positioning. The stationary state of the mobile station, its uniform rectilinear and uniformly accelerated movement are considered. The use of optimal estimation of the Kalman filter allows reducing the standard deviation of coordinates by 1.5-3 times for the considered mobile station trajectory.

The paper is devoted to investigation of SO2 emissions in atmospheric air using the OMI space monitoring database for the northern territories of the Krasnoyarsk region in Russia. The highest concentration of SO2 emissions was recorded in April 2019 - 41.2 DU, and the smallest in July 2019 - 0.5 DU. Actual air pollution in populated areas for the northern territories of the Krasnoyarsk Territory corresponds to a high degree of pollution, except for 2013 and 2014 when it was a moderate degree of pollution.
