Lipotso tsa motheo ka li-satellites

Li-satellite li hlaha joang? Ho buisana ka seea-le-moea ka sathelaete ke phello ea lipatlisiso sebakeng sa puisano, e le ho fumana kgolo e eketsehileng ea bokhoni ba ho sebetsa ka chelete e tlaase ka ho fetisisa.

Litšebeletso tse ling tse fanoang ke li-satellites? Tsamaiso ea lithelefono tsa thelevishene, tse li-link tse hōle, li boetse li na le bokhoni ba ho bokella kapa ho phatlalatsa lipontšo ho tloha sebakeng se seng ho ea ho se seng.

Setelethenete ke eng 'me e sebetsa joang? Ke pheta-pheto ea elektronike e sebakeng, e amohelang lipontšo tse hlahisitsoeng lefats'eng, e li matlafatsa le ho li romela lefatšeng. 'Me e sebetsa hobane seea-le-moeeng se nang le "A" se ntša pontšo e amoheloang ke satellite. Sathelaete e e phahamisa ebe e khutlisetsa hang-hang.
