    Project Description<\/h4>\n

    Vysk\u00fa\u0161anie zariadenia Pixla 1<\/strong> v prev\u00e1dzke. Zatia\u013e sa uskuto\u010dnili sk\u00fa\u0161ky zariadenia len v laborat\u00f3rnych podmienkach. Charakteristiky boli v\u00fdborn\u00e9 pre meranie smerov\u00fdch charakterist\u00edk rozsiahlych ant\u00e9nnych syst\u00e9mov. \u010eal\u0161\u00edm krokom je vysk\u00fa\u0161a\u0165 zariadenie v re\u00e1lnych podmienkach:\u00a0 pripevnen\u00e9 na kvadrokopt\u00e9ru, vynesen\u00e9 do v\u00fd\u0161ky stoviek metrov, kde tepelne a mechanicky nam\u00e1han\u00e1.<\/p>\n

    Zariadenie sme pripevnili ku kvadrokopt\u00e9re fy. Uavonic, nakonektovali ant\u00e9ny, v\u0161etko nastavili tak, aby pri vzlete kvadrokopt\u00e9ry v\u0161etko dr\u017ealo na svojich miestach v smeroch, ktor\u00e9 s\u00fa potrebn\u00e9 pre korektn\u00e9 meranie ve\u013ekosti elektromagnetick\u00e9ho po\u013ea, zistili, \u010di nedoch\u00e1dza k rezonanci\u00e1m pri vzlete a \u010dak\u00e1me na pekn\u00e9 po\u010dasie. Na\u0161im prv\u00fdm objektom bude Kamz\u00edk. Je tu dostato\u010dne ve\u013ea ant\u00e9nnych syst\u00e9mov, ktor\u00e9 vy\u017earuj\u00fa FM vysielanie s v\u00fdkonom jednej stanice a\u017e 100kW. Ak Pixla 1 vydr\u017e\u00ed tieto podmienky a korektne v\u0161etko nameria, tak vydr\u017e\u00ed v\u0161etko.<\/p>\n<\/div>\n<\/div>\n

    The Challenge in the design<\/h4>\n

    Meranie bolo uskuto\u010dnen\u00e9 v rann\u00fdch hodin\u00e1ch 6.5.2021 na vysiela\u010di Kamz\u00edk v Bratislave. Urobili sa tri kruhov\u00e9 oblety ve\u017ee vo vzdialenosti 100m, 200m a 300m. Tak isto aj oto\u010denie kvadrokop\u00e9ry so zariaden\u00edm Pixla 1 okolo svojej osi v geometrickom strede ant\u00e9nneho syst\u00e9mu, vyst\u00fapanie 100m nad tubus a klesnutie do 50m v\u00fd\u0161ky nad zemou. Merali sa dva 100kW a jeden 5,6 kW vysiela\u010de. Zariadenie na meranie elektrickej zlo\u017eky elektromagnetick\u00e9ho po\u013ea je navrhnut\u00e9 tak, aby bolo schopn\u00e9 sn\u00edma\u0165 a zaznamen\u00e1va\u0165 intenzitu ka\u017ed\u00fa sekundu a viac, pod\u013ea inicializ\u00e1cie pr\u00edstroja.<\/p>\n<\/div>\n

    \u00a0D\u00e1ta boli exportovan\u00e9 do excelu, kde zabrali cca 4700 riadkov. Ka\u017ed\u00fd riadok obsahoval n\u00e1zov merania, \u010das z\u00e1znamu, miesto (GPS s\u00faradnice) a nameran\u00e9 elektrick\u00e9 pole. Nako\u013eko d\u00e1ta z tak\u00fdchto meran\u00ed s\u00fa zna\u010dne za\u0161umen\u00e9 musel nasta\u0165 postprocesing – rozdelenie s\u00faborov, porovnanie s d\u00e1tami s kvadrokopr\u00e9ry a \u0161tatistick\u00e9 spravovanie.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
