"Imvula yeSatellite" engaqondakaliyo: Ngaphezu kwe-500 ye-Starlink LEO yeSathelayithi eziLahlekileyo kuMsebenzi weSola

Isehlo: Ukusukela kwilahleko engaqhelekanga ukuya kwizantyalantyala zemvula

Ukukhutshwa okukhulu kweesathelayithi ze-LEO ze-Starlink akuzange kwenzeke ngequbuliso. Ukusukela oko yasungulwa inkqubo ngo-2019, ilahleko yesathelayithi ibincinci ekuqaleni (i-2 ngo-2020), ihambelana namazinga alindelekileyo okuphuma. Nangona kunjalo, ngo-2021 wabona i-spike emangalisayo (ilahleko ezingama-78), elandelwa ngamanqanaba aphezulu azinzileyo (ama-99 ngo-2022, angama-88 ngo-2023). Ingxaki yafikelela incopho ngo-2024 xa kutsha iisathelayithi ezingama-316—amanani aphindwe kathathu eminyaka edlulileyo—ilahleko eyongezelelekileyo engama-583, elingana ne-1 satellite elahlekileyo yonke imihla okanye i-1 kwi-15 ayikwazanga ukugqibezela umsebenzi wayo.

Umsebenzi weSolar: Umtyholi ongabonakaliyo

Uphando lweNASA luqinisekisa unxibelelwano oluthe ngqo phakathi kwesathelayithi deorbiting kunye nemijikelo yelanga. Uphehlelelo luka-2019 lungqamane nobuncinci belanga, kodwa njengoko umsebenzi welanga usanda, ukutsalwa kwe-atmospheric kwi-340-550km orbits kunyuke nge-50% ngexesha lezaqhwithi ze-geomagnetic. Oku kwenzeka xa:

1. Amadangatye elanga abangelwe yi-Sunspot/i-coronal mass ejections ibhombu uMhlaba
2. Izaqhwithi zeGeomagnetic zifudumeza kwaye zandise umoya ongaphezulu
3. I-atmosfera eyandisiweyo iyakwandisa ukutsalwa, kubangela ukubola kwe-orbital

I-Paradox: Izaqhwithi ezibuthathaka zingqina ukuba zifile

Ngokuchasene noko kulindelekileyo, i-70% yelahleko yenzeke ngexesha eliphakathi / elibuthathaka lezaqhwithi ze-geomagnetic. Ezi ziganeko zithatha ixesha elide (iintsuku ezingapheliyo / iiveki) ngokuthe ngcembe zithobisa ii-orbits ezingaphaya kokubuyisela, ngokungafaniyo nezaqhwithi ezinamandla kodwa ezimfutshane. Umzekelo ophawulekayo: I-40 ye-49 ye-Starlink satellites esungulwe ngoFebruwari 2022 yoyiswa kwizaqhwithi ezingenamandla.

Urhwebelwano lwe-Low-Orbit ephantsi

Ngelixa ii-orbit ze-Starlink's 550km zenza unxibelelwano lwe-latency ephantsi, ukusondela kwabo kuMhlaba:

1. Inciphisa ubomi bokusebenza ukuya kwiminyaka eyi ~5 (vs. ISS's 400km orbit)
2. Yandisa imiphumo yokutsala ngexesha le-solar maxima
3. Ngokukodwa ibeka emngciphekweni iisathelayithi zovavanyo kwi-210km altitudes

Imingeni Yekamva

Nge>6,000 zesathelayithi zeStarlink ngoku ezijikelezayo ngexesha lobukhulu belanga-indibano yembali-izazinzulu zilumkisa ngale:

1. Isantya sesatellite esikhawulezileyo
2. Ukuncipha okunokwenzeka kwe-ozone kukukhutshwa kwe-aluminiyam oxide ngexesha lokungena kwakhona i-SpaceX ithomalalisa ilahleko ngokuphinda kuqaliswe ngokuphinda kuqaliswe kunye neeprothokholi ze-deorbit ezizenzekelayo, kodwa ukomelela komjikelo welanga kuhlala kungumba obalulekileyo kushishino.

Ukuqukumbela

Esi siganeko sigxininisa ukongamela kwendalo kubuchwepheshe bomntu kwaye siqaqambisa imfuneko yoyilo lwenkqubo ye-LEO ebangela iimpembelelo zelanga.

I-Chengdu Concept Microwave Technology CO., Ltd ngumvelisi oqeqeshiweyo wamacandelo e-5G/6G RF kunxibelelwano lwesathelayithi e-China, kubandakanywa ne-RF lowpass filter, i-highpass filter, i-bandpass filter, i-notch filter / i-band stop filter, i-duplexer, isahluli samandla kunye ne-coupler eyalathisayo. Zonke zinokulungiswa ngokweemfuno zakho.
