Deep Space Network

Anténa Goldstone v Kalifornii

Deep Space Network zkráceně DSN je mezinárodní síť antén agentury NASA, jejíž řízení zajišťuje Jet Propulsion Laboratory. DSN umožňuje komunikaci s vesmírnými sondami, které se nacházejí v meziplanetárním prostoru. DSN navíc provádí radiový průzkum sluneční soustavy i vzdálenějších částí vesmíru.[1] Tato síť je též využívána pro komunikaci s některými sondami, které obíhají přímo kolem Země.[1] Síť je tvořena trojicí stanic rozmístěných od sebe přibližně 120° zeměpisné délky:

Toto rozmístění stanic umožňuje nepřetržitou komunikaci s objekty ve vesmíru, i přes postupné otáčení Země.[2] Všechny tři stanice se nacházejí v lokální depresi obehnané horami, které fungují jako částečné stínění před okolním elektromagnetickým šumem.[2]

DSN je jednak využívána pro řízení a navigaci sond a dále pak pro příjem sondami vysílaných dat a vědeckých informací.[1][2] Vyjma americké NASA bylo vybavení (dle zdroje z roku 2004) využíváno i evropskou agenturou ESA a japonskou JAXA.[2]
