M robust bias-corrected weighted least squares iteration solution of mixed additive and multiplicative random error model

There are many methods for outlier detection and robust estimation in the field of geodesy, but most of them are based on the additive random error model (AREM). In the multiplicative random error model (MREM) or mixed additive and multiplicative random error model (MAMREM), outlier detection or robust estimation is less studied. Based on the bias-corrected weighted least squares (bcWLS) iteration solution of the MAMREM, combined with the conventional M robust estimation in the AREM, this paper proposes an M robust bcWLS iteration solution suitable for the MAMREM. The analysis of the examples shows that the proposed method can obtain better parameter estimation and more reasonable mean square error of unit weight when the observations contain outliers, which verifies the feasibility and preponderance of the proposed method.

Research on anthropogenic influence on satellite positioning accuracy

This paper presents the results of research into the accuracy of satellite-based positioning methods in the vicinity of operating industrial and energy facilities. Modern dual-frequency multi-system satellite receivers allow for high accuracy and productivity in compliance with the basic principles of work related to ensuring the criterion of unity of measurements and the mandatory implementation of the rules of localisation of the object and the receiver(s), as well as the study of geometric and temporal factors of satellite passage, with their subsequent application to perform quality measurements. This technique is widely and effectively used on large area and linear objects by qualified specialists in the field of geodesy. The accuracy of determinations is guaranteed by the openness of the sky and the absence of all kinds of man-made factors that potentially interfere with the reception of radio signals. This paper does not consider the extreme operation of receivers in areas of special signal suppression. It is of great interest to research the accuracy of satellite positioning methods in the vicinity of operating industrial and energy objects.

GEODETIC PLANNING IN THE AGRICULTURAL LANDSCAPE: CREATION OF DIGITAL MAPS AND MODELS FOR LAND USE OPTIMIZATION

The article is devoted to the topical issue of geodetic planning in agro-landscape and its importance for efficient land use. The authors review modern methods and technologies for creating digital maps and models of agricultural landscapes based on the use of geographic information systems and aerial photography from unmanned aerial vehicles. Modern new approaches to geodetic planning within agrolandscapes are investigated. The requirements of the agricultural sector for digital mapping and modeling for the optimal use of land resources are determined. The tools for the formation of digital maps of agro-territories of united territorial communities are substantiated. Proposals for the use of geodetic methods for effective agro-landscape planning are formulated. The main attention is paid to the practical significance of the data obtained for optimizing land use, planning agricultural operations and rational use of land resources. The studied approaches and developments can be useful for farmers, landowners, ecologists and specialists in the field of geodesy. In the course of the study, a methodology and procedure for mapping agricultural landscapes using GIS and aerial survey materials using UAVs were developed. This methodology made it possible to obtain high-quality images of agricultural landscapes and develop a cartographic model in GIS based on them. The approach was successfully tested on the example of the selected model area near the ATC. The created digital map and database are promising for further research of agricultural landscapes. The research clearly shows that the data obtained as a result of UAV surveys is a high-quality source of reliable information. Aerial photography allows you to quickly create an accurate digital terrain model, which can serve as the basis for geographic information systems in the development of a number of thematic maps and terrain models important for the agricultural sector. The geographic information system makes it possible to visualize the main elements of agricultural landscapes as separate layers (e.g., relief, soil-forming rocks) with appropriate detailing of their characteristics in attribute tables. By combining different data sources, GIS allows you to create detailed maps of the agro-ecological conditions of a particular area. GIS can also be used to store information on field work, yields and other indicators, which ensures the rational management of agricultural processes on land plots.

THE PROBLEM OF RELIABILITY OF GEODESIC NETWORKS

Nowadays, the theory of reliability is widely used in the construction industry, and it is also used in the field of geodesy. By abstracting its position, it can be successfully transferred to systems that, it would seem, are not in a dynamic state. Let's take, for example, the points of the polygonal (leveling) network in the city. It would seem that such a network is in a static state, but over time it undergoes changes, that is, it is in imperceptible dynamics and its reliability gradually decreases.
 Reliability in the broadest sense of the word means the ability of a technical device (system, network) to operate without interruption (failure) for a given period of time under certain conditions. Such a period of time is usually determined by the time of execution of some task, which is carried out by the device or system and is part of the general operational task.
 Currently, the problem of reliability is becoming one of the central problems of engineering and management organization. Ensuring the reliable operation of all system elements is of primary importance.
 The modern interpretation of the term "reliability" in geodesy is associated with Baard's reliability theory, according to which reliability is defined as "the ability of the network to self-monitor against gross errors [1]. One of the indicators of reliability is the minimum amount of gross error that can be detected after statistical analysis of the corrections obtained after equalization. On this path, many difficulties arise, most of which remain unsolved, namely the impossibility of localizing a gross error, quantitative assessment of reliability, methods of designing reliable geodetic networks. The unsatisfactory state of reliability theory limits its practical application, but at the same time, the problem of product reliability is the main one in modern production and its importance is growing all the time. In this regard, there is an acute problem in highlighting new views on solutions to this problem in the field of designing and creating geodetic networks.
 A new scheme for constructing the theory of reliability of geodetic measurements is proposed. Its basis is a probabilistic determination of reliability, a system of tolerances, and methods of localizing gross errors. Reliability is defined as a probabilistic measure of the homogeneity of measurements that have passed control. Quantitative reliability is estimated by three indicators: differential, integral and the minimum gross error. The Neumann-Pearson criterion is recommended for establishing tolerance. This theory makes it possible to design geodetic networks with a given reliability.

Simulation of the influence of parameters of disturbing vibration accelerations on the operation of a new two-channel transformer gravimeter

A new two-channel transformer gravimeter of an automated aviation gravimetric system was considered, the accuracy of which is higher than gravimeters known today. Its design was described. The influence of the parameters of disturbing vibrational accelerations on the operation of a new two-channel transformer gravimeter was simulated. The influence of frequencies and amplitudes of perturbing accelerations for the most unfavorable resonant cases on the operation of a two-channel transformer gravimeter was studied using a computer. After all, today there are no scientific, theoretical and practical works devoted to researching the possibility and expediency of using a two-channel transformer gravimeter as an AGS gravimeter. The transformer gravimeter contains a sensitive element consisting of a magnetic circuit, a movable armature, a primary excitation winding and a secondary output winding having two identical sections. Two sections of the secondary winding are connected in series-opposite, and the movable armature is connected to the motor, which, with a certain period, lowers the armature down and lifts it up along the magnetic circuit, and the motor is controlled by a switching device connected to the control voltage source, and the output signal from the secondary output winding is fed to the input of the output signal calculator, where an output signal is generated that is proportional to twice the value of the gravitational acceleration. A transformer gravimeter is a means of measuring the vertical component of the gravitational acceleration vector from an aircraft and can be used in the field of geodesy, geophysics, in particular, in the formation of reference gravimetric grids in hard-to-reach areas of the globe, as well as in aircraft and rocket building. The transformer gravimeter is part of the aviation gravimetric system placed on the aircraft.

ANALYSIS OF METHODS FOR DIGITAL TERRAIN MODELING BASED ON SPATIAL INTERPOLATION (Part 1)

Digital Elevation Model (DEM) is an important component of geodetic works, which allows reproducing the earth's surface in digital form with a certain level of detail. Various methods are used to construct DEMs, among which it is worth noting the methods based on spatial interpolation. One advantage of spatial interpolation is the ability to take into account the uneven distribution of points on the earth's surface, which provides a more accurate DEM. With the spread of high-precision geodetic instruments and technologies such as GPS and LiDAR, the methods of constructing DEMs have significantly improved. Modern methods include interpolation of curved surfaces, smoothing methods that reduce noise and random errors, and adaptive filtering methods that can detect and correct data anomalies. In the field of geodesy, digital elevation models are an essential element in performing measurements and creating project documentation for construction. The purpose of this article is to analyze existing methods for constructing digital elevation models and to compare them to choose the best one. For the analysis, the widely known geoinformation system package Surfer was selected, which contains a sufficiently large number of deterministic methods and a geostatistical method based on spatial interpolation. The Golden Software Surfer geoinformation system is currently the industry standard for constructing graphical representations of two-variable functions. An unbeatable advantage of the program is its built-in spatial interpolation algorithms, which allow creating digital surface models with high quality for spatially unevenly distributed data. The Surfer program provides 12 different methods of spatial interpolation. For the analysis, a random fragment of a topographic map was taken, which was previously digitized and exported in ASCII format with ready-made coordinates for constructing a DEM. However, only 6 out of the 12 methods that could more accurately reflect the real relief situation were further analyzed based on these topographic data, namely Kriging, Triangulation with Linear Interpolation, Radial Basic Function, Natural Neighbor, Modified Shepard`s Method and Minimum Curvature. Keywords: digital elevation model, construction methods, spatial interpolation, geographic information system, Surfer.

Новації у геодезично – картографічній та земельно-кадастровій діяльності й удосконалення змісту підготовки фахівців з геодезії та землеустрою

Starting from the 80s of the last century, especially rapidly developing technical directions are based on the use of high-precision ground instruments, aerospace based systems and serve to obtain information about the earth’s surface, the outer space, the study of various processes and phenomena of living and non-living nature. The methods of processing this information on the basis of modern technologies of geodesy and cartography and those related to them: engineering geodesy, satellite geodesy, remote sensing, photogrammetry, cadastre of territories, land and real estate valuation differ both in different theoretical approaches and in the principles of practical implementation. The problem is the automatic storage, transformation and use of huge volumes of information in the solution of modern theoretical and thematic tasks. The proposed article presents the latest achievements that have become the achievement of the specified industries and which are already used and developed by the world’s leading firms and corporations. In many universities of the world, the works of scientists appear in which they analyze the field of modern knowledge related to geodesy and land management. The article mentions the rapid technological changes in the field of geodetic-cartographic and land-cadastral activities that have taken place during the last decades, which significantly affect the nature and content of the work that will be performed by future specialists in the field of geodesy and land management. The directions of development of geodetic and land management education in relation to the needs of the domestic and world market of engineering services are considered.

THE STATE LAND CADASTRE IN THE V.I. VERNADSKY NOOSPHERIC CONCEPT

Cadastral systems are most often a geo-information system that ensures the accumulation and storage of typical information, for example, the state land cadastre is a single state geo-information system of information about lands located within the state border of Ukraine, their purpose, restrictions on their use, as well as data on the quantitative and qualitative characteristics of lands, their assessment, on the distribution of lands between owners and users, on land reclamation networks and constituent parts of land reclamation networks But the use of standard cadastres does not allow solving a wide range of complex tasks related to information about land, real estate, water resources, etc., therefore, it conditions the development of conceptual provisions for the creation of an integrated intelligent cadastral system. Modern cadastres solve a narrow range of typical tasks, mainly providing the user with up-to-date information for solving private typical tasks. An attempt to integrate separate cadastral systems and the development of special programs that support decision-making by users (stakeholders) in various spheres of human activity will lead to a synergistic effect and the creation of collective artificial intelligence. This work formulates the problem of creating an information management system based on the methods of geomatics, as well as the methods and concepts of V. I. Vernadskyi's teaching. In our opinion, the weakening of the contradictions of the formulated problem lies in the way of creating a theoretical and methodological base, which should take into account the features of spatially distributed information modelling, as well as the creation of knowledge models in the field of geodesy and land management. The authors of this article are convinced that a new methodological paradigm of V. I. Vernadskyi's teaching is currently being formed. This belief is based on the great possibilities of modern information technologies, the development of modern geodetic instrumentation, as well as the results of modelling objects that require both high-precision measurements and soft calculations and linguistic assessments. The land cadastral information and management system should include executive and management subsystems and take into account the features of spatially distributed information modelling, as well as the creation of knowledge models in the field of geodesy and land management. Keywords: state land cadastre, geoinformation system, geomatics, information management system, cadastral data.

Solution for ill-posed EIV model regularization attending to its decreasing regularization characteristic

Abstract The errors-in-variables (EIV) model is used for data processing in the field of geodesy. However, the EIV model may be ill-posed. By analyzing the decreasing regularization (D-regularization) characteristic of solutions for EIV models, algorithms using traditional methods such as singular value decomposition or the Tikhonov function can directly determine the irrationality of a model. When an EIV model is ill-posed, solutions in which the observation errors in the coefficient matrix are simulated by variables make the ill-posed nature of the model more serious. This is because the simulated observation errors are subtracted from the coefficient matrix in subsequent computations, which reduces the singular value of the normal matrix. This point is verified using an example. To account for the D-regularization of solutions in EIV models, a modified algorithm is derived by classifying the models into two categories, and the regularization parameters are iteratively revised based on the mean squared error. Finally, some conclusions are drawn from two separate examples.

Neural ODE Differential Learning and Its Application in Polar Motion Prediction

AbstractThis paper introduces a new learning algorithm for accurate, physically driven time series prediction. The fundamental assumption behind the method is that the phenomena follow Ordinary Differential Equations. We investigate the general case where the time series follows an ODE of degree . The resulting method is a learning algorithm based on the finite differences between the values of time series. We present the application of the method in the field of geodesy for polar motion prediction, the main objective of the present paper. We show that in this application, the linear form of the method is sufficient and offers competitive predictive performance. We present a baseline solution, in which we use historical polar motion time series from 1976 to predict up to the year 2020. The prediction horizon in this case is short‐term (up to 10 days into the future). In addition, we compare the prediction accuracy in the short‐term horizon with the results of the best performing model in the first Earth Orientation Prediction Comparison Campaign. On average, a 53% improvement in prediction performance is achieved. In further analyses, we compare the prediction accuracy for both short‐term and long‐term against the results of state‐of‐the‐art methods, namely Multichannel Singular Spectrum Analysis, and a combination of Singular Spectrum Analysis and Copula sampling. We show that the proposed method in this paper can outperform the mentioned two methods in both short and long‐term horizons, with an average improvement of the prediction performance of 54% and 52%, respectively.

Зарубежная оценка советских топографических карт как показатель профессиональной образовательной подготовки

The main historical stages of education, the Soviet period of formation and development of the military topographic school, which celebrates its 200th anniversary this year, are considered. It is noted that training specialists in the field of geodesy, topography and cartography made the core of the educational process regardless to political and military changes. The direct impact of the knowledge gained by graduates on extraterritorial mapping of inaccessible territories is shown in the view of quality. According to the comments from foreign specialists and experts, their assessment of the created topographic maps and plans is presented with the allocation of completeness and details of the information. The main published research works concerning to evaluation of domestic topographic maps and plans created for foreign territory within the framework of the Soviet cartographic project are given. It is proved that development and implementation of a cartographic project were largely determined by the professional education system which existed in the Soviet epoch, including training specialists in Leningrad Military Topographic school, rearranged later into Higher Military Topographic Command one.

A study of the EGM2008 model of Earth's gravitational field

AbstractThe Earth Gravity Model 2008 (EGM2008) is now some years old, and yet information on how to use it to calculate Earth's gravity remains obscure outside the field of geodesy. We describe the mathematics necessary to implement EGM2008, and use this to discuss several points of the model: its sensitivity to the number of spherical harmonics being summed, nuances and a trap for physicists and mathematicians in the normalisation it uses, and a comparison with other work. We conclude that one must not overestimate the precision shown by a global-fit model such as EGM2008.

Performance Evaluation and Requirement Analysis for Chronometric Leveling with High-Accuracy Optical Clocks

The high-precision unification of global height datum has long been a hot issue in the field of geodesy. The chronometric leveling method originates from the gravitational redshift effect of general relativity, which may provide a new solution for the unification of global height datum. The height difference between the two locations could be measured via the frequency comparison of high-precision optical clocks. We build the error model for chronometric leveling, mainly including the measurement systematic error of two optical clocks, frequency statistical error of two optical clocks, and transmission path error of optical fiber when using optical fiber as carrier. Then, we put forward the schemes to achieve chronometric leveling. The performance of the height measurement using different schemes is evaluated. Additionally, considering the requirements of geodesy, four typical height measurement accuracy factors for chronometric leveling are proposed. Meanwhile, the corresponding accuracy requirements for optical clocks and frequency transmission techniques are also given. It has important guiding significance for the unification of the global height datum and related geoscience fields using high-accuracy chronometric leveling in the future.

3D concept creation of permanent geodetic monitoring installations and the a priori assessment of systematic effects using Virtual Reality

Abstract Logistic processes of construction sites are transferred into virtual and full 3D environments to increase the interoperability for all project partners. These digital twins are emerging for the construction process of modern building processes and are already designed to be used for the operation of the building afterwards. In structural health monitoring (SHM) the sensor installations are also designed to monitor the structure over its whole lifespan. Therefore, the embedding process and the operation of the sensor systems and the Building Information Modelling (BIM) have overlapping long-term goals. Beside these 3D software advances in civil engineering, the working environments in the field of geodesy still follow more established approaches. In many cases using only 2D CAD plans and on-site visits at the existing structure are best practice for the design of geodetic monitoring installations. This paper describes the improvement of the concept creation of permanent monitoring systems with geodetic total stations in an interactive virtual 3D environment. The simulated instruments are behaving according to their specification data and are linked with a physics engine to automatically detect common problems in a network design like obstructed line of sights, disadvantageous incidence angles at the targets or automatic aiming issues due to multiple targets in the field of view. Furthermore, the Virtual Reality (VR) technology is introduced as a user interface for a virtual 3D planning environment. The functionality of the developed VR application is tested in a real-life use case for the feasibility study of the automatic monitoring of a railway tunnel.

MODERN PROGRAMS FOR PROCESSING DATA OF GEODESIC DIMENSIONS

Modern software used for processing field geodetic surveys was studied. Every year, geodetic production faces new tasks that require a quick and correct solution. The modern level of automation of geodetic work is characterized by the widespread distribution of electronic total stations and satellite receivers, digital aerial photography complexes, field portable computers, as well as multifunctional software packages. This requires the use of new technologies and an automated information processing system, which includes the availability of a software complex for processing field measurement materials, means of automated data entry and graphical information, programs for processing graphics and automated drawing, devices for outputting graphic and textual information. The software for processing the received data of geodetic measurements should be such that the most complex tasks are performed, and at the same time it is easy to use. The development of software tools for processing geodetic measurements will help to reduce the time for camera data processing. The article evaluates the software in terms of the possibility of their practical implementation in the field of geodesy, as well as in terms of accessibility, comprehensibility and the presence of additional functions. An analysis of the functionality of the most widespread in Ukraine modern software complexes for processing the results of ground surveying, such as: CADdy, FieldWorks, Topograd, Topocad, and CREDO, designed for processing the results of geodetic measurements and designing the construction, reconstruction, repair of highways and transport interchanges, was carried out. including public roads, city streets and roads of all technical categories. Based on the analysis of the functionality of modern software complexes designed to process the results of geodetic measurements and the design, reconstruction and capital repair of highways, appropriate conclusions were formed.

SOFTWARE ANALYSIS IN THE FIELD OF GEODESY

In connection with the development of modern geodetic technologies, there is a need to quickly and efficiently perform automated processing of source data. Today, the market for surveying software is diverse and is divided into common products and specialized software packages. Geodetic works are not possible without the use of geographic information technologies and software. Therefore, the purpose of this article is a detailed analysis of the software packages used in Ukraine, as well as an analysis of their capabilities, accessibility, clarity and additional functions in the field of geodesy. Geodetic works belong to the tasks of geoinformation analysis, and with the help of modern electronic geodetic equipment increases the accuracy of work, the processing of which is carried out by computer-aided design (CAD). After analyzing the functionality of software products, we can conclude that most of them are not fully functioning automated products of full-scale systems. An important factor when choosing a software package is the ability to use for free or the low cost of a license to use. But, in addition to cost, when choosing a product, considerable attention is paid to the complexity of implementation and operation of such CAD. Among the most famous representatives that have proven themselves in Ukraine, we can highlight such packages as CREDO III, Digitals, and software packages created on the CAD platform. In general, such programs are set up by companies that have direct links with Western firms to facilitate data resolution. Other products can only be used to solve specific tasks of a narrower direction. When choosing a software, it is important that the program meets the objectives and processes all types of topographic and geodetic works. The application and implementation of new software packages in the field of geodesy provides greater accuracy and quality of topographic and geodetic works. When choosing software, many Ukrainian business leaders, as experience shows, focus on CREDO III, Digitals and CAD software packages to be able to work in a single information space at different stages of project development.
