Ukwabiwa kwebhendi yesiqhelo yeNkqubo yoKuhambahamba yeBeidou

Inkqubo yeSathelayithi yokuHamba ngeBeidou (i-BDS, ekwaziwa ngokuba yiCOMPASS, uguqulelo lwesiTshayina: iBeiDou) yinkqubo yehlabathi yokuhamba ngesathelayithi eyaphuhliswa ngokuzimeleyo yiTshayina. Yinkqubo yesithathu evuthiweyo yokuhamba ngesathelayithi emva kweGPS kunye neGLONASS.

Isizukulwana sokuqala saseBeidou

Ukwabiwa kwebhendi yamaza ombane kwiBeidou Generation I kubandakanya ikakhulu iibhendi zeRadio Determination Satellite Service (RDSS), ezahlulwe ngokukodwa kwiibhendi ze-uplink kunye ne-downlink:
a) Ibhendi ye-Uplink: Le bhendi isetyenziselwa izixhobo zomsebenzisi ukudlulisa imiqondiso kwiisathelayithi, kunye noluhlu lwamaza oluqala kwi-1610MHz ukuya kwi-1626.5MHz, oluphantsi kwebhendi ye-L. Olu yilo lwebhendi luvumela izixhobo zomhlaba ukuba zithumele izicelo zokubeka kunye nolunye ulwazi olufanelekileyo kwiisathelayithi.
b) Ibhendi yeDownlink: Le bhendi isetyenziselwa iisathelayithi ukudlulisa imiqondiso kwizixhobo zomsebenzisi, kunye noluhlu lwamaza oluqala kwi-2483.5MHz ukuya kwi-2500MHz, oluphantsi kwebhendi ye-S. Olu yilo lwebhendi luvumela iisathelayithi ukubonelela ngolwazi lokuhamba, idatha yokubeka indawo, kunye nezinye iinkonzo ezifunekayo kwizixhobo ezisemhlabeni.
Kuyaphawuleka ukuba ukwabiwa kwebhendi yamaza omoya kwiBeidou Generation I kwakujoliswe ekuhlangabezaneni neemfuno zobugcisa kunye neemfuno zokuchaneka kokubeka indawo ngelo xesha. Ngophuhliso lwetekhnoloji kunye nokuphuculwa okuqhubekayo kwenkqubo yeBeidou, izizukulwana ezalandelayo, kuquka iBeidou Generation II kunye neIII, zamkela iindlela ezahlukeneyo zamaza omoya kunye neendlela zokuguqula isignali ukubonelela ngeenkonzo zokuzulazula kunye nokubeka indawo ezichanekileyo nezithembekileyo.

Isizukulwana sesiBini saseBeidou

I-Beidou Generation II, inkqubo yesizukulwana sesibini se-Beidou Navigation Satellite System (BDS), yinkqubo yokuhamba ngesathelayithi efikelelekayo kwihlabathi liphela eyaphuhliswa ngokuzimeleyo yiTshayina. Ngokusekwe kwisiseko se-Beidou Generation I, ijolise ekuboneleleni ngeenkonzo ezichanekileyo nezithembekileyo zokubeka, ukuhamba, kunye nexesha (PNT) kubasebenzisi kwihlabathi liphela. Le nkqubo inamacandelo amathathu: indawo, umhlaba, kunye nomsebenzisi. Icandelo lesithuba liquka iisathelayithi ezininzi zokuhamba, icandelo lomhlaba liquka izikhululo zolawulo eziphambili, izikhululo zokubeka esweni, kunye nezikhululo ze-uplink, ngelixa icandelo lomsebenzisi liquka izixhobo ezahlukeneyo zokwamkela.
Ukwabiwa kwebhendi yefrikhwensi yeBeidou Generation II kubandakanya ikakhulu iibhendi ezintathu: i-B1, i-B2, kunye ne-B3, kunye neeparameter ezithile ngolu hlobo lulandelayo:
a) Ibhendi ye-B1: Uluhlu lweefrikhwensi ze-1561.098MHz ± 2.046MHz, ezisetyenziswa kakhulu kwiinkonzo zokuhambisa nokubeka abantu abaqhelekileyo.
b) Ibhendi ye-B2: Uluhlu lweefrikhwensi ze-1207.52MHz ± 2.046MHz, ezikwasetyenziswa kakhulu kwiinkonzo zaseburhulumenteni, zisebenza kunye nebhendi ye-B1 ukubonelela ngezakhono zokubeka iifrikhwensi ezimbini ukuphucula ukuchaneka kweendawo.
c) Ibhendi ye-B3: Uluhlu lweefrikhwensi ze-1268.52MHz ± 10.23MHz, ezisetyenziswa kakhulu kwiinkonzo zasemkhosini, zibonelela ngokuchaneka okuphezulu kokubeka kunye nokukwazi ukulwa nokuphazamiseka.

Isizukulwana sesithathu saseBeidou

Inkqubo yoKuhamba ngeenyawo yesizukulwana sesithathu iBeidou, ekwaziwa ngokuba yiBeidou-3 Global Navigation Satellite System, yinkqubo yokuhamba ngesatellite efikelelekayo kwihlabathi liphela eyakhiwe kwaye iqhutywa yiTshayina ngokuzimeleyo. Ifikelele kwinqanaba ukusuka kwindawo ukuya kwihlabathi liphela, inika iinkonzo zokuma, ukuhamba, kunye nexesha ezichanekileyo, ezithembekileyo kakhulu kubasebenzisi kwihlabathi liphela. IBeidou-3 inikezela ngemiqondiso emininzi yenkonzo evulekileyo kwiibhendi zeB1, B2, kunye neB3, kubandakanya iB1I, B1C, B2a, B2b, kunye neB3I. Ukwabiwa rhoqo kwezi signals kulandelayo:
a) Ibhendi ye-B1: B1I: ​​Ifrikhwensi esembindini ye-1561.098MHz ± 2.046MHz, isignali esisiseko esetyenziswa kakhulu kwizixhobo ezahlukeneyo zokukhangela; B1C: Ifrikhwensi esembindini ye-1575.420MHz ± 16MHz, isignali eyintloko exhasa iisathelayithi ze-Beidou-3 M/I kwaye ixhaswa ziiterminals ezintsha, eziphezulu zeselula.
