directional angle

Modern navigation equipment should make it possible to determine in real-time the location of a ground-moving object (NRA) and the direction of its movement. To solve such problems, the equipment of consumers (AS) of satellite radio navigation systems (SRNS) is widely used. However, a number of circumstances, such as traffic in tunnels, and forests, within dense urban areas, the presence of natural and man-made radio interference, do not provide continuous reception of information from the necessary grouping of navigation Satellites.

Purpose of this work is the investigation of the accuracy of plans of Lviv in 1844 and 1931. Methodology. The main criterion for evaluation of the authenticity of ancient maps is the study of their geometric accuracy, which is determined by the magnitudes of errors that arise when measuring lengths, angles, coordinates, and other cartometric attributes.
