Abstract

System for å sende data til et flertall av satellitter er angitt. En første satellitt (320) i et orbitalvindu har en assosiert mottaksantenne, og er konfigurert til å ta imot signaler i et første område av frekvenser. En andre satellitt (316) i orbitalvinduet har en assosiert mottaksantenne. Den andre satellitten (316) er separert fra den første satellitten (320) med i det minste en første separasjonsvinkel og er konfigurert til å ta imot signaler i det første området av frekvensene. En første bakkeopplinkantenne (308b), lokalisert på en første bakkelokasjon, er i stand til å sende en første opplinkestråle (328a) på mottaksantennen til den første satellitten (320). En andre bakkeopplinkantenne (308b), sammenstilt på den første bakkelokasjonen, er i stand til å sende en andre opplinkstråle (324a) på mottaksantennen til den andre satellitten (316). Den første opplinkstrålen (328a) inkluderer første signaler på det første området av frekvensene, og den andre opplinkstrålen (324a) inkluderer andre signaler på det første området av frekvensene. Videre vil den første opplinkstrålen (328a) være vesentlig attenuert utover den første separasjonsvinkelen i retningen til den andre satellitten (316), og den andre opplinkstrålen (324a) er vesentlig attenuert utover den første separasjonsvinkelen i retningen til den første satellitten (320).
