Popis misie

Veronika, prvá družica s osobným príbehom, je pomenovaná po dcére slovenského podnikateľa Borisa Procíka a vyniká svojou nápaditou ružovou farbou. Okrem toho, že predstavuje prvý „rodinný satelit“, otvára dvere pre vzdelávacie a popularizačné aktivity s cieľom zapojiť školy do skutočného vesmírneho bádania. Tento projekt podporuje Deutsche Schule Bratislava a PLANETUM – Hvězdárna a planetárium hl. m. Prahy. Dizajn, stavbu a operovanie družice zabezpečuje česko-slovenská firma Spacemanic.

Z technického hľadiska družica obsahuje dvojicu kamier na snímkovanie Zeme, dvojicu rádií pracujúcich v pásme UHF a VHF, anténny subsystém, napájací systém a solárne panely, palubný počítač, GNSS prijímač a unikátny systém na určenie a riadenie orientácie družice. Okrem vzdelávacích a popularizačných aktivít tak družica overí niekoľko nových technológií pre budúce vesmírne misie.

Parametre palubných kamier

Družica bude pracovať v rádioamatérskom pásme a rádioamatérom a ďalším záujemcom poskytne zaujímavé služby a aktivity. Koordináciu frekvencií zabezpečil Rádioklub Leteckej fakulty Technickej univerzity v Košiciach OM3KSI v spolupráci s Úradom pre reguláciu elektronických komunikácií a poštových služieb.
