Kwishyira hamwe kwa Satelite-Ubutaka Byahindutse Inzira rusange

Kugeza ubu, hamwe n’iterambere rya buhoro buhoro StarLink, Telesat, OneWeb na AST gahunda yo kohereza ibyogajuru by’inyenyeri, AST itumanaho rya orbit rirongera kwiyongera. Ihamagarwa ryo "guhuza" hagati y'itumanaho rya satelite n'itumanaho rya selile ku isi naryo riragenda ryiyongera. Chen Shanzhi yizera ko impamvu nyamukuru zibitera ari iterambere mu ikoranabuhanga n'impinduka zikenewe.

Ku bijyanye n’ikoranabuhanga, imwe ni iterambere ry’ikoranabuhanga ryo kohereza ibyogajuru, harimo udushya tw’ikoranabuhanga twangiza nka “umwambi umwe ufite satelite nyinshi” hamwe n’ibicuruzwa bya roketi; icya kabiri ni iterambere ryikoranabuhanga rikora ibyogajuru, harimo iterambere ryibikoresho, gutanga amashanyarazi, hamwe nikoranabuhanga ritunganya; icya gatatu ni tekinoroji yumuzunguruko Iterambere rya satelite, miniaturizasiya, modularisation, hamwe nibigize satelite, no kongera ubushobozi bwo gutunganya ubwato; icya kane niterambere ryikoranabuhanga ryitumanaho. Hamwe nihindagurika rya 3G, 4G, na 5G, antene nini nini, milimetero Umuhengeri Hamwe niterambere ryimiterere nibindi, tekinoroji ya terefone igendanwa yo ku isi irashobora no gukoreshwa kuri satelite.

Kuruhande rwibisabwa, hamwe no kwagura ibikorwa byinganda nibikorwa byabantu, ibyiza byo gutumanaho ibyogajuru bikwirakwizwa kwisi yose hamwe no gukwirakwiza ikirere bitangiye kwigaragaza. Kuva uyu munsi, gahunda y'itumanaho rya terefone igendanwa ku isi imaze gukwirakwiza abaturage barenga 70%, ariko kubera tekiniki n'ubukungu, ikora 20% gusa by'ubutaka, bingana na 6% gusa bishingiye ku buso bw'isi. Hamwe niterambere ryinganda, indege, inyanja, uburobyi, peteroli, kugenzura ibidukikije, ibikorwa byo hanze yumuhanda, hamwe ningamba zigihugu ndetse n’itumanaho rya gisirikare, nibindi, birakenewe cyane ahantu hanini no gukwirakwiza ikirere.

Chen Shanzhi yizera ko guhuza terefone zigendanwa na satelite bivuze ko itumanaho rya satelite ryinjira ku isoko ry’abaguzi kuva ku isoko ry’inganda. Ati: "Icyakora, birasekeje kuvuga ko Starlink ishobora gusimbuza cyangwa guhindura 5G." Chen Shanzhi yerekanye ko itumanaho rya satelite rifite aho rigarukira. Iya mbere ni ubwishingizi butemewe bwakarere. Satelite eshatu zo hejuru-izenguruka irashobora gukwirakwiza isi yose. Amajana ya satelite yo munsi ya orbit igenda kumuvuduko mwinshi ugereranije nubutaka kandi irashobora gupfuka gusa. Ibice byinshi bitemewe kuko mubyukuri nta bakoresha. ; Icya kabiri, ibimenyetso bya satelite ntibishobora gutwikira mu nzu no hanze bitwikiriwe n'inzira zirenga n'amashyamba yo mu misozi; icya gatatu, miniaturizasi ya terefone ya satelite no kuvuguruzanya hagati ya antene, cyane cyane abantu bamenyereye muri antenne yubatswe ya terefone zigendanwa zisanzwe (abakoresha nta bwenge bafite), Terefone igendanwa ya satelite yubucuruzi iracyafite antenne yo hanze; icya kane, imikorere yuburyo bwitumanaho rya satelite iri hasi cyane ugereranije niyitumanaho rya terefone igendanwa. Imikorere ya Spectrum iri hejuru ya 10 bit / s / Hz. Hanyuma, kandi cyane cyane, kubera ko ikubiyemo amasano menshi nko gukora ibyogajuru, kohereza ibyogajuru, ibikoresho byubutaka, ibikorwa bya satelite na serivisi, kubaka no gukora no gufata neza buri cyogajuru cyitumanaho nikubye inshuro icumi cyangwa inshuro magana zubutaka. sitasiyo fatizo, bityo amafaranga yitumanaho aziyongera rwose. Kurenza 5G itumanaho rya selire kwisi.

Ugereranije na sisitemu y'itumanaho rya terefone igendanwa ku isi, itandukaniro nyamukuru rya tekinike n'imbogamizi za sisitemu y'itumanaho rya satellite ni ibi bikurikira: 1) Ibiranga ikwirakwizwa ry'umuyoboro wa satelite n'umuyoboro wo ku isi biratandukanye, itumanaho rya satelite rifite intera ndende yo gukwirakwiza, ibimenyetso byo gukwirakwiza inzira gutakaza ni binini, kandi gutinda kohereza ni binini. Kuzana imbogamizi zihuza ingengo yimari, umubano wigihe na gahunda yo kohereza; ) Kurugero, terefone igendanwa ni metero magana make kugeza kuri kilometero kuva kuri sitasiyo yubutaka, kandi 5G irashobora gushyigikira umuvuduko wihuta wa 500km / h; mugihe icyogajuru gito cya orbit kiri nko kuri 300 kugeza 1.500 km uvuye kuri terefone igendanwa, kandi icyogajuru kigenda ku muvuduko wa 7.7 kugeza 7.1km / s ugereranije nubutaka, burenga 25.000km / h.
