Published: May 2024

The article defines the main issues and prospects for the development of the ecocity concept in terms of sustainable development. In the process of identifying the main problem, the relevance of the research was determined. Having conducted a thorough analysis of the existing state of ecocities formation in conditions of sustainable development, it was found that the development of ecocities is multi-vector and includes energy-efficient, ecological and economic aspects, while the impact on the environment is minimal. The main trends in the development of ecocities were identified, which made it possible to determine their role in the formation of a modern urban environment in terms of increasing the energy efficiency of buildings, using solar energy, "green" technologies and the latest materials. On the basis of the conducted research, the main directions of urban development of the ecocity were determined: ecological construction and energy saving, use of alternative energy sources, ecotransport, waste disposal, creation of ecological infrastructure.
The main recommendations that must be followed to improve the ecocity: use of ecological materials (reduction of the ecological footprint of the product), use of ecological production processes, the maximum efficiency of using the resource potential of products by considering the life cycle of the product from creation to disposal, high product quality for extended service life, minimization of repairs and mandatory reprocessing.
Therefore, it can be concluded that the creation of ecologically favorable conditions in settlements is a rather complex process.
ANALYSIS OF ATMOSPHERIC AIR POLLUTION IN KYIV FOR 2014-2024
Authors: Solukha Igor 
Published: May 2024

Considered changes in the state of atmospheric air pollution in the city of Kyiv for 2014-2024 within the city limits.
It was established that, in accordance with the analysis of atmospheric air indicators, during the analyzed period, the level of atmospheric air pollution in the territory of the city of Kyiv was mainly in the range of "very low" and "low".
The main dependence of the quality of atmospheric air in the city of Kyiv on the emissions of mobile sources of influence, namely road transport, as the main source of atmospheric air pollution, has been established.
Air pollution is one of the most important environmental problems in Kyiv. Urban transport is the main factor of atmospheric air pollution, the influence of the "car-road" system on the natural environment in the conditions of the city is much greater than that of industry and heat energy, which is connected with a large number of motor vehicles, the presence of large areas of roads and streets.
Motor vehicle emissions are represented by exhaust gases (after fuel combustion), crankcase gases (a mixture of fuel with vapors of lubricants) and fuel evaporation entering the environment from fuel tanks, carburetors and engine power systems. The most significant emission components are carbon monoxide, hydrocarbons, nitrogen oxides, sulfur compounds, solid particles (soot).
Atmospheric air pollution problems should also include the increase in the number of autonomous boiler houses in the city, because in connection with the growing pace of the city's development, there is a discrepancy in the real ability of energy companies to provide heat to consumers. Currently, the centralized urban heat networks are already overloaded, and the addition of additional consumers requires the installation of additional heat-generating equipment of the appropriate capacity. There is a need to use modern progressive boiler units with as low as possible pollutant emission rates, to implement energy-saving technologies, to solve the problem of achieving minimum losses on the way to transport heat to consumers, etc.
The further study of the analysis of the state of the atmospheric air in large cities of Ukraine based on the experience of other countries for the better development of the concept of ecological development and the implementation of an ecological assessment of the state of the environment is substantiated.
MODERN METHODS OF DETERMINING PLUMBLINE AND GEOID SURFACE DEFERENCES

Published: May 2024

Today, global navigation satellite systems (GNSS) are widely used for the development of national geodetic networks and geodetic research. However, there are some applications where GNSS observations should be integrated with traditional ground-based geodetic measurements (e.g., underground engineering surveys, monitoring of hydraulic structures, etc.) In order to integrate GNSS observations and traditional measurements using a high-precision anti-aircraft camera, it is necessary to know the deviation of the plumb line, defined as the angle between the gravity vector and the ellipsoidal normal at a given point.
If the astronomical and ellipsoidal coordinates are determined simultaneously, you can immediately obtain the values of the plumb line deviations. Using the values of the deviations of the plumb lines, you can determine the undulations (ondulations) of the geoid using astronomical and geodetic leveling. You can also determine the orthometric height if you know the height of the ellipsoid (GPS) and the waviness of the geoid.
A CCD sensor with a telescope pointed at the zenith, in combination with DGPS, allows you to determine the ellipsoidal coordinates, as well as the astronomical coordinates in about half an hour with high accuracy.
Determining the deviations of plumb lines using a portable DSC set and a GPS receiver is a fairly convenient and compact measurement tool. The experimental studies of the high-precision anti-aircraft camera confirmed the theoretical calculations; in particular, the accuracy of determining astronomical coordinates does not exceed ±0.35". The maximum fluctuation of the values of the components of the plumb lines deviation in the meridian plane was 0.45˝, and in the plane of the first vertical - 0.80˝.
