However, one of the most pressing challenges revolves around energy sources, encompassing both heat and electricity supply. Arctic settlements are typically considered off-grid systems, necessitating the development of systems of locally generated energy that are both reliable and sustainable. The goal of GLOB is to measure solar irradiation on as many as possible array planes to verify recorded values with modeled. Due to technical and costs limitations a sphere with 26 faces called rhombicuboctahedron has been pointed as most suitable for this project. The rhombicuboctahedron is a polyhedron comprised of 8 triangles and 18 squares. For this project, elements with edges measuring 10 cm for both squares and triangles have been constructed. The bottom-facing square element isn't utilized for irradiation data collection. This is because a stainless steel pipe has been employed as a support leg, passing through the bottom square and reaching the top face, which is horizontally oriented. All components required for building the rhombicuboctahedron have been meticulously designed using CAD software, and the corresponding files compatible with most 3D printers have been attached for your convenience. The elements created in CAD software used to assemble GLOB system SENSORS AND OTHER ELECTRONIC COMPONENTS Following components has been used to build complete system: 26 self-powered silicon-cell pyranometers type SP110, 1 temperature probe 107 manufactured by Campbell Sci., CR1000x logger, AM16/32B Multiplexer, CELL215 LTE modem, 7 Ah 12V battery, solar charging regulator, 20W photovoltaic module.
