Gushyira hamwe umurongo wa Frequency wa Sisitemu yo Kuyobora ya Beidou

Sisitemu ya Beidou Navigation Satellite (BDS, izwi kandi nka COMPASS, ihinduranya ry'ibisobanuro mu gishinwa: BeiDou) ni sisitemu yo kuzenguruka satelite ku isi yakozwe ku giti cyayo n'Ubushinwa. Ni sisitemu ya gatatu yo kugenzura satelite imaze gukura ikurikira GPS na GLONASS.

Igisekuru cya mbere cya Beidou

Uburyo bwo gutanga umurongo wa frequency wa Beidou Generation I bukoreshwa cyane cyane mu miyoboro ya Radio Determination Satellite Service (RDSS), igabanyijemo imiyoboro ya uplink na downlink:
a) Uplink Band: Iyi band ikoreshwa mu bikoresho biyikoresha mu kohereza ibimenyetso kuri satelite, ifite frequency iri hagati ya 1610MHz na 1626.5MHz, iy’itsinda rya L. Iyi band ifasha ibikoresho byo ku butaka kohereza ubusabe bwo gushyira ibintu aho biri n’andi makuru ajyanye na byo kuri satelite.
b) Umugozi wo Kumanuka: Uyu mugozi ukoreshwa kuri satelite zohereza ibimenyetso ku bikoresho bikoresha, hamwe n'intera iri hagati ya 2483.5MHz na 2500MHz, iy'umugozi wa S. Uyu mugozi utuma satelite zitanga amakuru yo kugenda, amakuru yo gushyira ibintu ku butaka, n'izindi serivisi zikenewe ku bikoresho biri ku butaka.
Ni ngombwa kumenya ko uburyo bwo gushyira frequency band muri Beidou Generation I bwagenewe ahanini kuzuza ibisabwa mu ikoranabuhanga no gushyira neza aho ibintu biherereye muri icyo gihe. Hamwe n'iterambere ry'ikoranabuhanga no kuvugurura buri gihe sisitemu ya Beidou, ibisekuruza byakurikiyeho, harimo na Beidou Generation II na III, byakoresheje uburyo butandukanye bwo gushyiraho frequency band no guhindura ibimenyetso kugira ngo bitange serivisi zo kugenzura no gushyira ibintu mu buryo bwizewe kandi bunoze.

Igisekuru cya kabiri cya Beidou

Igisekuru cya kabiri cya Beidou, sisitemu y’icyiciro cya kabiri cya Sisitemu ya Beidou Navigation Satellite (BDS), ni sisitemu yo kugenzura satelite ikoreshwa ku isi yose yakozwe n’Ubushinwa ku giti cyayo. Ishingiye ku ishingiro rya Beidou Generation I, igamije gutanga serivisi nziza kandi zizewe zo gushyira ibintu ku isi hose, kuyobora no gufata igihe. Iyi sisitemu igizwe n’ibice bitatu: umwanya, ubutaka, n’umukoresha. Igice cy’ikirere kigizwe n’ibyogajuru byinshi byo kugenzura, igice cy’ubutaka kigizwe n’ibice by’ubuyobozi, sitasiyo zo kugenzura, na sitasiyo zo gushyiramo amakuru, mu gihe igice cy’umukoresha kigizwe n’ibikoresho bitandukanye byo kwakira amakuru.
Uburyo bwo gushyira hamwe umurongo wa frequency wa Beidou Generation II bugizwe ahanini n'imirongo itatu: B1, B2, na B3, hamwe n'ibipimo byihariye bikurikira:
a) Umugozi wa B1: Intera y'inshuro 1561.098MHz ± 2.046MHz, ikoreshwa cyane cyane mu kuyobora no gutanga serivisi zo kugenzura indege za gisivili.
b) Umugozi wa B2: Intera y'umuvuduko wa 1207.52MHz ± 2.046MHz, ikoreshwa cyane cyane mu mirimo ya gisivili, ikorana na B1 band kugira ngo itange ubushobozi bwo gushyiramo umurongo inshuro ebyiri kugira ngo yongere ubuhanga bwo gushyiramo umurongo.
c) Umugozi wa B3: Intera y'ingufu za 1268.52MHz ± 10.23MHz, ikoreshwa cyane cyane mu bikorwa bya gisirikare, itanga ubushobozi bwo gushyira ibintu neza no gukumira inzitizi.

Igisekuru cya gatatu cya Beidou

Sisitemu yo kuzenguruka ya Beidou yo mu gisekuru cya gatatu, izwi kandi nka Beidou-3 Global Navigation Satellite System, ni sisitemu yo kuzenguruka ya satelite ikoreshwa ku isi yose yubatswe kandi ikoreshwa n'Ubushinwa ku giti cyayo. Yageze ku ntambwe iva ku rwego rw'akarere ijya ku rwego rw'isi, itanga serivisi zo gushyira mu mwanya, kuyobora, no gufata igihe ku bakoresha ku isi yose neza kandi zizewe. Beidou-3 itanga ibimenyetso byinshi bifunguye kuri serivisi zitandukanye muri B1, B2, na B3, harimo B1I, B1C, B2a, B2b, na B3I. Ingano y'ibi bimenyetso ni iyi ikurikira:
a) Umugozi wa B1: B1I: ​​Ingano yo hagati ya 1561.098MHz ± 2.046MHz, ikimenyetso cy'ibanze gikoreshwa cyane mu bikoresho bitandukanye byo kuyobora; B1C: Ingano yo hagati ya 1575.420MHz ± 16MHz, ikimenyetso cy'ibanze gishyigikira satelite za Beidou-3 M/I kandi gishyigikiwe n'ibyuma bishya kandi byo mu rwego rwo hejuru bigendanwa.
b) Umugozi wa B2: B2a: Ingano yo hagati ya 1176.450MHz ± 10.23MHz, ikaba n'ikimenyetso cy'ibanze gishyigikira satelite za Beidou-3 M/I kandi iboneka kuri terminal nshya kandi zo hejuru; B2b: Ingano yo hagati ya 1207.140MHz ± 10.23MHz, ishyigikira satelite za Beidou-3 M/I ariko iboneka gusa kuri terminals za telefoni zo hejuru zatoranijwe.
c) Umugozi wa B3: B3I: Frequency yo hagati ya 1268.520MHz ± 10.23MHz, ishyigikiwe na satelite zose zo muri Beidou Generation II na III, hamwe n'ubufasha bwiza buturutse kuri modules zifite uburyo bwinshi n'uburyo bwinshi.

Chengdu Concept Microwave Technology CO., Ltd ni uruganda rw'umwuga rukora ibice bya 5G/6G RFkuriItumanaho rya satelite mu Bushinwa, harimo filter ya RF lowpass, filter ya highpass, filter ya bandpass, filter ya notch/band stop, duplexer, power divider na coupler y'icyerekezo. Byose bishobora guhindurwa hakurikijwe ibyo ukeneye.
