Kun satelliitti on laukaistu, sen teht\u00e4v\u00e4n onnistuminen riippuu usein kyvyst\u00e4 olla yhteydess\u00e4 siihen ja seurata sen etenemist\u00e4. Toukokuusta 1968 l\u00e4htien suurin osa ESA:n puolesta laukaistuista satelliiteista on ollut Saksan Darmstadtissa sijaitsevan Euroopan avaruusoperaatiokeskuksen (ESOC) valvonnassa.<\/p>\n<\/div>\n

Keskukseen kuuluu p\u00e4\u00e4valvomo, joka toimii toiminnan keskuksena teht\u00e4v\u00e4n alkuvaiheissa. Kun satelliitti on otettu k\u00e4ytt\u00f6\u00f6n, toiminta siirret\u00e4\u00e4n pienempiin, erikoistuneisiin valvomoihin. ESOC:n ty\u00f6 alkaa heti, kun teht\u00e4v\u00e4 on alustavasti otettu tutkittavaksi. Teht\u00e4v\u00e4n edetess\u00e4 ja kehittyess\u00e4 ESOC tutkii kaikkia lennonohjauksen, satelliittitoiminnan ja viestinn\u00e4n n\u00e4k\u00f6kohtia.<\/p>\n

Kun satelliitti on laukaistu, keskuksen on seurattava ja ohjattava sit\u00e4. T\u00e4h\u00e4n kuuluu komentojen l\u00e4hett\u00e4minen avaruusaluksen asennon tai kiertoradan muuttamiseksi sek\u00e4 sen toiminnan tarkkailu sen varmistamiseksi, ett\u00e4 se toimii moitteettomasti. ESOC valvoo my\u00f6s aluksella olevia mittalaitteita ja l\u00e4hett\u00e4\u00e4 uusia ohjeita tarvittaessa.<\/p>\n

ESOC:n asiantuntijat ovat pelastaneet useita teht\u00e4vi\u00e4, jotka n\u00e4yttiv\u00e4t menetetyilt\u00e4. Niihin kuuluu Hipparcos, joka onnistui saattamaan kolmivuotisen t\u00e4htikartoitusteht\u00e4v\u00e4ns\u00e4 p\u00e4\u00e4t\u00f6kseen huolimatta siit\u00e4, ett\u00e4 se oli juuttunut v\u00e4\u00e4r\u00e4lle kiertoradalle.<\/p>","protected":false},"excerpt":{"rendered":"
