METHODOLOGY FOR DETERMINING HELMERT'S CONSISTENT PARAMETERS FOR LOCAL TERRITORIES

A method for determining the Helmert matching parameters for converting the coordinates of points from the common terrestrial to the reference coordinate system has developed. The tech-nique is based on the maximum alignment of the surfaces of the common terrestrial and reference el-lipsoids within a certain local territory and does not imply knowledge of the heights of the quasigeoid. The radius of the local area is limited by a given methodological error in the transformation of coordi-nates from general terrestrial system to Gauss-Kruger projection. For a methodical error of ±2–3 cm, the radius of the local area is about 200 km. Two options for determining the Helmert matching parameters for the fourth three-degree zone of the MSC of the Novosibirsk region are given: according to the reconstructed coordinates and heights of the SDGN, and according to the catalog coordinates and heights of the SGN points located in the same territory.

THE CRITERION FOR TRANSFERABLE SELF-CONSISTENTLY TRANSLATIONALITY OF COORDINATE TRANSFORM OPERATORS AND REFERENCE FRAMES IN UNIVERSAL KINEMATICS

From an intuitive point of view universal kinematics are collections (sets) of changing objects, which evolve, being in a certain spatial-geometric environment, and evolution of whi- ch can be observed from many different frames of reference. Moreover, the definition of uni- versal kinematics impose the existence of some (preassigned) universal coordinate transform between every two reference frames of such kinematics. Transferable self-consistently translati- onal reference frames (in vector universal kinematics) are interesting because for such reference frames it is possible to give a clear and unambiguous definition of displacement of a moving reference frame relative to a fixed one, which does not depend on the choice of a fixed point in the moving frame of reference. In the present paper it is shown that an arbitrary reference frame m is transferable self-consistently translational relatively to a reference frame l (in some vector uni- versal kinematics F) if and only if the coordinate transform operator from the reference frame m to the reference frame l is transferable self-consistently translational. Therefore transferable self-consistently translational coordinate transform operators describe the conversion of coordi- nates from the moving and transferable self-consistently translational frame of reference to the (given) fixed frame in vector universal kinematics. Also in the paper it is described the structure of transferable self-consistently translational coordinate transform operators (this is the main result of the article). Using this result it have been obtained the necessary and sufficient conditi- on for transferable self-consistently translationality of one reference frame relatively to another in vector universal kinematics.

Maintenance accounting and usage of organizational capabilities

One approach to improving an organization’s activities is an approach aimed at regulating its capabili-ties. This approach is applied in many fields of activity, but most extensively and consistently in the defense sphere of developed countries, NATO, and recently in Ukraine. The scale and complexity of the tasks that need to be addressed within the capability-based approach make it necessary to support these activities with appropriate tools. In this paper, we propose a conceptual model of accounting and use of capabilities. This model, the principal feature of which is the distinction between nominal and actual activity plans, has two components: static and dynamic. The static component of the model is a set of entities, relationships between them, as well as attributes of entities and relationships between entities. The main entities are capability and carrier of capability. There are nominal carriers of capabilities (exist only on paper) and actual carriers (instances of nominal carrier, for which, at a minimum, the coordi-nates of their location can be specified). The division into types, as well as the use of metamodels for describing capabilities and carriers of capabilities are supposed. The requirements to both the capability and the carrier of the capability can be advanced. Both actual carriers of capabilities as a whole and their (actual) capabilities are subject to assessment. Dynamic component of the model – the activity support-ed by the model – breaks up into accounting and use of capabilities. The model is supplemented by a component that allows to record the requirements and assessments of the capability carrier with distri-bution to various components of its resource (DOTMLPF-distribution). The proposed model can be used as the basis for creating the appropriate information technology.
