Technick\u00e9 vybaven\u00ed projektu vyu\u017e\u00edv\u00e1 meteorologick\u00fdch radiosond, kter\u00e9 n\u011bkolikr\u00e1t denn\u011b vypou\u0161t\u00ed \u010cHM\u00da<\/a> v Praze a v Krom\u011b\u0159\u00ed\u017ei. Krom\u011b \u010cHM\u00da vypou\u0161t\u011bj\u00ed stejn\u00e9 nebo podobn\u00e9 sondy meteorologick\u00e9 \u00fastavy po cel\u00e9m sv\u011bt\u011b.<\/p>\n\n\n\n

B\u011b\u017en\u00e1 meteosonda obsahuje mikrokontrol\u00e9r \u0159ady STM32, \u010dip generuj\u00edc\u00ed modulaci na kmito\u010dtu v p\u00e1smu 400-405 MHz, GPS modul, \u010didla teploty, vlhkosti, p\u0159\u00edpadn\u011b dal\u0161\u00edch fyzik\u00e1ln\u00edch veli\u010din. Sonda je upevn\u011bna na bal\u00f3nu ze samodegraduj\u00edc\u00ed pry\u017ee, kter\u00e1 se v p\u0159\u00edrod\u011b rychle rozpad\u00e1 – pokud takovou sondu najdete, m\u016f\u017eete zbytky bal\u00f3nu vyhodit do b\u011b\u017en\u00e9ho odpadu. Sondy obvykle dolet\u00ed do v\u00fd\u0161ky 32-35 kilometr\u016f, kde bal\u00f3n praskne, a sonda potom voln\u00fdm p\u00e1dem slet\u00ed zp\u011bt na zem.<\/p>\n\n\n\n

Nalezen\u00e1 sonda se nemus\u00ed vracet, pokud se nejedn\u00e1 o sondu se speci\u00e1ln\u00edmi \u010didly; v takov\u00e9m p\u0159\u00edpad\u011b byste ale na\u0161li na p\u0159\u00edmo na sond\u011b informace o postupu vr\u00e1cen\u00ed. D\u00edky servisn\u00edmu konektoru je mo\u017en\u00e9 p\u0159eprogramovat procesor, kter\u00fd je potom schopen pracovat s modulac\u00ed APRS p\u0159\u00edpadn\u011b RTTY v radioamat\u00e9rsk\u00e9m p\u00e1smu 433 MHz – a pr\u00e1v\u011b tato mo\u017enost je z\u00e1kladem nau\u010dn\u00e9ho programu Dotkni se Vesm\u00edru, o kter\u00fd se star\u00e1 radioklub OK1RAJ.<\/p>\n\n\n\n

Z nalezen\u00fdch sond byla vytvo\u0159ena s\u00e9rie radioamat\u00e9rsk\u00fdch sond, kter\u00e9 m\u016f\u017eete sledovat a\u017e do 7. \u0159\u00edjna na kmito\u010dtu 433,690 MHz modulac\u00ed RTTY se zdvihem 450 Hz a rychlost\u00ed 300 Bd. Volac\u00ed znaky jsou „neradioamat\u00e9rsk\u00e9“ – TTS a \u010d\u00edslo.<\/p>\n\n\n\n
