Sisitemu ya Satelite ya Beidou (BDs, izwi kandi nka kompas, ibisobanuro byubushinwa: beidou) ni sisitemu yo kugenda kwa satelite ku isi yigenga yateye imbere nubushinwa. Nuburyo bwa gatatu bwo kugenda kwa satellite nyuma ya GPS na Glonass.
Igisekuru cya Beidou I.
Gutanga imirongo ya Frequency yo mu Gisekuru cya Beidou na burimo cyane cyane imitwe ya Satellite (RDSS), igabanijwe cyane cyane mu kuzamuka no kumanuka ku maguru:
a) Itsinda rya UPLINK: Iri tsinda rikoreshwa kubikoresho byabakoresha kugirango dushyire ibimenyetso kuri satelite, hamwe na 1610mhz kugeza 1626.5mhz, muri l-itsinda. Iki gishushanyo cyemerera ibikoresho byubutaka kugirango wohereze ibyifuzo nibindi bisobanuro bifatika kuri satelite.
b) Itsinda ryamanutse: Iri tsinda rikoreshwa kuri satelite ryo kohereza ibimenyetso kubikoresho byabakoresha, hamwe nurwego rwa metero 2483.5mhz kugeza 2500mhz, uri mu itsinda. Iki gishushanyo gishushanya gishoboza Saatelite gutanga amakuru yo kugenda, amakuru yumwanya, nizindi serivisi zikenewe mubikoresho byo hasi.
Birashimishije kubona ko inshuro ebyiri zinyura mu gisekuru cya Beidou nagenewe cyane kubahiriza ibisabwa bya tekiniki no gushyira neza ibyo bisabwa. Hamwe niterambere ryikoranabuhanga no kuzamura bikomeza kuri sisitemu ya Beidou, ibisekuruza byakurikiyeho, harimo na Beidou Igisekuru cya II na III, byemejwe na serivisi zinyuranye zo gutanga ibimenyetso byinshi kandi byizewe hamwe na serivisi zizewe.
Beidou Igisekuru II
Igisekuru cya Beidou Igisekuru cya II, igisekuru cya kabiri cya Sisitemu ya Satelite ya Beidou (BDs), ni uburyo bwo kugenda ku isi igenda yisumbuye bwateye imbere n'ubushinwa. Kubaka ku gisekuru cya Beidou I, igamije gushyira ahagaragara neza, kwizerwa-kwizerwa, kugendana, serivisi (PNT) kubakoresha ku isi yose. Sisitemu igizwe n'ibice bitatu: umwanya, ubutaka, n'umukoresha. Igice cyo mu kirere kirimo Saatelite nyinshi zo kugenderamo, igice cyo ku isi kirimo umutware wo kugenzura sitasiyo, gukurikirana sitasiyo, na sitasiyo, mu gihe igice cy'umukoresha kigizwe n'ibikoresho bitandukanye byo kwakira.
Gutanga imirongo ya Frequency ya Beidou Igisekuru cya IIID ikubiyemo cyane cyane imitwe itatu: B1, B3, na B3, hamwe nibipimo byihariye kuburyo bukurikira:
a) B1 Itsinda: Urutonde rwa 1561.098mhz ± 2.046mhz, ikoreshwa cyane cyane kubijyanye no kugendana nabasivili na serivisi zumwanya.
b) b2 bande: Urutonde rwa 1207.52mhz ± 2.046mhz, nanone ikoreshwa cyane kubikorwa bya gisivili, bikorana nitsinda rya B1 kugirango bahe ubushobozi bwa B1 kugirango babone ubushobozi bwuzuye.
c) B3 Band: Urutonde rwa 1268.52mhz ± 10.23mHz, zikoreshwa cyane kubikorwa bya gisirikare, itanga ubushobozi bwo hejuru neza kandi ubushobozi bwo kurwanya.
Bidou Igisekuru III
Sisitemu ya gatatu ya Beidou, izwi kandi nka Sitelite ya Beidou-3 ku isi yose, ni sisitemu yo kugendana kwisi yose yubatswe yigenga kandi ikorwa nubushinwa. Imaze kugera ku gusimbuka mu karere kugeza ku isi, itanga ubushishozi bukomeye, gushyira mu gaciro byinshi, kugendana, kugendana, no gutanga akazi kubakoresha kwisi yose. Beidou-3 itanga ibimenyetso byinshi bya serivisi muri B1, B2, na B3, harimo B1I, B1C, B2a, B3I. Gutangiza inshuro nyinshi muri ibyo bimenyetso ni ibi bikurikira:
a) B1 Itsinda: B1I: Centre Ibirindiro byo kuwa 1561.098MHZ ± 2.046mhz, ikimenyetso cyibanze gikoreshwa cyane mubikoresho bitandukanye byimikorere; B1C: Inshuro yo hagati yo 1575.420mhz ± 16mhz, gushyigikira ibimenyetso byibanze bya beidou-3 m / i satelite kandi ishyigikiwe na terefone igendanwa.
b) B2 Band: B2a: Inshuro yo hagati ya 1176.450MHz ± 10.23mhz, kandi ishyigikira ibimenyetso byibanze bya beidou-3 m / i satelites mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile mobile igendanwa; B2B: Inshuro yo hagati ya 1207.140MHz ± 10.23mhz, gushyigikira beidou-3 m / i satelite ariko iboneka gusa guhitamo terminal igendanwa.
c) B3 Band: B3I: Hagati ya 1268.520MHz ± 10.23MHz, ishyigikiwe na satelite zose muri BYINSHI zombi, module nyinshi.
