“Imvula Yesathelayithi” Eyimfihlakalo: Amasathelayithi e-Starlink LEO Angaphezu kuka-500 Alahlekile Ngenxa Yomsebenzi Welanga

Isigameko: Kusukela Ekulahlekelweni Okungahleliwe Kuya Ekunabeni

Ukuqhekeka okukhulu kwamasathelayithi e-LEO e-Starlink akuzange kwenzeke ngokuzumayo. Selokhu kwaqalwa uhlelo ngo-2019, ukulahlekelwa kwamasathelayithi ekuqaleni kwakuncane kakhulu (okubili ngo-2020), okuhambisana namazinga okwehla okulindelekile. Kodwa-ke, u-2021 wabona ukwanda okukhulu (ukulahlekelwa okungu-78), kulandelwa amazinga aphezulu aqhubekayo (99 ngo-2022, 88 ngo-2023). Inkinga yafinyelela esicongweni ngo-2024 ngamasathelayithi angu-316 asha—izibalo zonyaka odlule kathathu—ngokuhlangene kwaba ukulahlekelwa okungu-583, okulingana nesathelayithi esingu-~1 esilahlekile nsuku zonke noma esisodwa kweziyi-15 esihlulekile ukuqeda umsebenzi waso.

Umsebenzi Welanga: Icala Elingabonakali

Ucwaningo lwe-NASA luqinisekisa ukuhlangana okuqondile phakathi kokukhishwa kwesathelayithi kanye nemijikelezo yelanga. Ukwethulwa kuka-2019 kwahambisana nokuncipha kwamandla elanga, kodwa njengoba umsebenzi welanga wanda, ukuhudula komkhathi emizuliswaneni engu-340-550km kwanda ngo->50% ngesikhathi seziphepho ze-geomagnetic. Lokhu kwenzeka lapho:

1. Ukuvutha kwelanga okubangelwa amachaphaza elanga/ukukhishwa kwe-coronal mass kuqhumisa uMhlaba
2. Iziphepho ze-geomagnetic ziyashisa futhi zandisa umkhathi ongaphezulu
3. Umkhathi owandisiwe wandisa ukuhudula, okubangela ukubola kwe-orbital

Indida: Iziphepho Ezibuthakathaka Zibonisa Ukubulala Kakhulu

Ngokuphambene nokulindelekile, u-70% wokulahlekelwa kwenzeke ngesikhathi seziphepho ze-geomagnetic eziphakathi nendawo/ezibuthakathaka. Lezi zenzakalo ezinde (izinsuku/amasonto ahlala isikhathi eside) ziwohloka kancane kancane ngendlela engenakuphola, ngokungafani neziphepho ezinamandla kodwa ezimfushane. Isibonelo esiphawulekayo: Amasathelayithi angu-40 kwangu-49 e-Starlink aqalwa ngoFebhuwari 2022 anqotshwa yiziphepho ezibuthakathaka eziqhubekayo.

Ukushintshana kwe-Low-Orbit

Nakuba imijikelezo ye-Starlink engamakhilomitha angu-550 ivumela ukuxhumana okubambezeleka okuphansi, ukusondela kwayo eMhlabeni:

1. Ikhawulela isikhathi sokusebenza sibe yi-~5 yeminyaka (uma kuqhathaniswa nomjikelezo we-ISS ongu-400km)
2. Yandisa imiphumela yokuhudula ngesikhathi se-solar maxima
3. Ikakhulukazi ibeka engcupheni amasathelayithi okuhlola ekuphakameni okungamakhilomitha angu-210

Izinselele Zesikhathi Esizayo

Njengoba amasathelayithi e-Starlink angaphezu kuka-6,000 manje ejikeleza ngesikhathi sokukhanya kwelanga okukhulu—ukuhlangana komlando—ososayensi baxwayisa ngalokhu:

1. Ukuncipha kwesathelayithi okusheshisiwe
2. Ukuncipha okungenzeka kwe-ozone ngenxa yokukhishwa kwe-aluminium oxide ngesikhathi sokufakwa kabusha kwe-SpaceX kunciphisa ukulahlekelwa ngokuqaliswa kokugcwalisa kabusha okusheshayo kanye nezinqubo ze-deorbit ezenzakalelayo, kodwa ukuqina komjikelezo welanga kusalokhu kuyinto ebalulekile embonini yonke.

Isiphetho

Lo mcimbi ugcizelela ukubusa kwemvelo ngaphezu kobuchwepheshe babantu futhi ugcizelela isidingo sokuklama izinhlelo ze-LEO ezibangela ithonya lelanga elijikelezayo.

I-Chengdu Concept Microwave Technology CO.,Ltd ingumkhiqizi ochwepheshe wezingxenye ze-5G/6G RF zokuxhumana ngesathelayithi eShayina, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/band stop, i-duplexer, i-Power divider kanye ne-directional coupler. Zonke zingenziwa ngezifiso ngokwezidingo zakho.
