Uhlelo lwesathelayithi lokuzulazula lwe-Beidou (BDS, olwaziwa nangokuthi i-COMPASS, ukuhumusha ngesiShayina: BeiDou) luhlelo lokuzulazula lwesathelayithi lomhlaba wonke olwakhiwe ngokuzimela yiShayina. Luhlelo lwesithathu oluvuthiwe lokuzulazula lwesathelayithi olulandela i-GPS ne-GLONASS.
Isizukulwane I saseBeidou
Ukwabiwa kwebhendi yemvamisa yeBeidou Generation I kuhilela kakhulu amabhendi e-Radio Determination Satellite Service (RDSS), ahlukaniswe ngokukhethekile ngamabhendi e-uplink kanye ne-downlink:
a) Ibhendi ye-Uplink: Le bhendi isetshenziselwa imishini yomsebenzisi ukudlulisa amasignali kumasathelayithi, enobubanzi bemvamisa obungu-1610MHz kuya ku-1626.5MHz, obungobebhendi ye-L. Lo mklamo webhendi uvumela imishini ephansi ukuthumela izicelo zokubeka kanye nolunye ulwazi olufanele kumasathelayithi.
b) Ibhendi Yokudonsela Ezansi: Leli bhendi lisetshenziselwa amasathelayithi ukudlulisa izimpawu emishinini yomsebenzisi, enobubanzi bemvamisa obungu-2483.5MHz kuya ku-2500MHz, obungobebhendi ye-S. Lo mklamo webhendi uvumela amasathelayithi ukuthi anikeze ulwazi lokuzulazula, idatha yokubeka, kanye nezinye izinsizakalo ezidingekayo emishinini esemhlabeni.
Kuyaphawuleka ukuthi ukwabiwa kwebhendi yemvamisa yeBeidou Generation I kwaklanyelwe ngokuyinhloko ukuhlangabezana nezidingo zobuchwepheshe kanye nezidingo zokunemba kokubeka ngaleso sikhathi. Ngokuthuthuka kobuchwepheshe kanye nokuthuthukiswa okuqhubekayo ohlelweni lweBeidou, izizukulwane ezalandela, okuhlanganisa iBeidou Generation II kanye ne-III, zamukela amabhendi emvamisa ahlukene kanye nezindlela zokuguqula isignali ukuze zinikeze izinsizakalo zokuzulazula kanye nokubeka ezinembile kakhulu nezithembekile.
Isizukulwane Sesibili saseBeidou
Isizukulwane sesibili se-Beidou, uhlelo lwesizukulwane sesibili lwe-Beidou Navigation Satellite System (BDS), luhlelo lokuzulazula lwesathelayithi olufinyeleleka emhlabeni wonke olwakhiwe ngokuzimela yiShayina. Ngokwakhela phezu kwesisekelo sesizukulwane se-Beidou I, luhlose ukuhlinzeka ngezinsizakalo zokubeka, ukuzulazula, kanye nesikhathi (PNT) ezinembile kakhulu, ezinokwethenjelwa kakhulu kubasebenzisi emhlabeni jikelele. Uhlelo luqukethe izingxenye ezintathu: isikhala, umhlabathi, kanye nomsebenzisi. Ingxenye yesikhala ihlanganisa amasathelayithi amaningi okuzulazula, ingxenye yomhlabathi ihlanganisa iziteshi zokulawula eziyinhloko, iziteshi zokuqapha, kanye neziteshi zokuxhumanisa, kuyilapho ingxenye yomsebenzisi ihlanganisa amadivayisi ahlukahlukene okwamukela.
Ukwabiwa kwebhendi yemvamisa yeBeidou Generation II kuhlanganisa kakhulu amabhendi amathathu: i-B1, i-B2, ne-B3, kanye namapharamitha athile alandelayo:
a) Ibhendi ye-B1: Ibanga lemvamisa elingu-1561.098MHz ± 2.046MHz, elisetshenziswa kakhulu ezinsizeni zokuzulazula nezokubeka izindiza zabantu abavamile.
b) Ibhendi ye-B2: Ibanga lemvamisa elingu-1207.52MHz ± 2.046MHz, elisetshenziswa kakhulu ezinkonzweni zomphakathi, lisebenza eceleni kwebhendi ye-B1 ukuhlinzeka ngamakhono okubeka amaza amabili ukuze kuthuthukiswe ukunemba kokubeka.
c) Ibhendi ye-B3: Ibanga lemvamisa elingu-1268.52MHz ± 10.23MHz, elisetshenziswa kakhulu ezinkonzweni zempi, linikeza ukunemba okuphezulu kokuma kanye namakhono okulwa nokuphazamiseka.
Isizukulwane Sesithathu saseBeidou
Uhlelo Lokuzulazula lwesizukulwane sesithathu lwe-Beidou, olwaziwa nangokuthi i-Beidou-3 Global Navigation Satellite System, luhlelo lokuzulazula lwesathelayithi olufinyeleleka emhlabeni wonke olwakhiwe futhi oluqhutshwa yiShayina ngokuzimela. Lufinyelele ijubane elivela endaweni ethile kuya emhlabeni wonke, luhlinzeka ngezinsizakalo zokubeka, ukuzulazula, kanye nesikhathi ezinembile kakhulu kubasebenzisi emhlabeni jikelele. I-Beidou-3 inikeza amasignali amaningi esevisi evulekile kuwo wonke ama-B1, B2, kanye nama-B3 band, kufaka phakathi i-B1I, B1C, B2a, B2b, kanye ne-B3I. Ukwabiwa kwemvamisa yalezi zimpawu kungokulandelayo:
a) Ibhendi ye-B1: B1I: Imvamisa ephakathi engu-1561.098MHz ± 2.046MHz, isignali eyisisekelo esetshenziswa kabanzi kumadivayisi ahlukahlukene okuzulazula; B1C: Imvamisa ephakathi engu-1575.420MHz ± 16MHz, isignali eyinhloko esekela amasathelayithi e-Beidou-3 M/I futhi esekelwa ama-terminals amasha, asezingeni eliphezulu eselula.
b) Ibhendi ye-B2: B2a: Imvamisa ephakathi engu-1176.450MHz ± 10.23MHz, futhi iyisignali eyinhloko esekela amasathelayithi e-Beidou-3 M/I futhi itholakala kuma-terminal amasha, asezingeni eliphezulu eselula; B2b: Imvamisa ephakathi engu-1207.140MHz ± 10.23MHz, esekela amasathelayithi e-Beidou-3 M/I kodwa itholakala kuphela kuma-terminal akhethiwe asezingeni eliphezulu eselula.
c) Ibhendi ye-B3: I-B3I: Imvamisa ephakathi engu-1268.520MHz ± 10.23MHz, esekelwa yizo zonke iziphuphutheki kokubili esizukulwaneni sesi-Beidou II kanye nesesi-III, ngokusekelwa okuhle kakhulu okuvela kumamojula wemodi eminingi, amamvamisa amaningi.
