Ukwabiwa kwe-Frequency Band of Beidou Navigation System

Uhlelo lwe-Satellite System ye-Beidou navigation (BDS, eyaziwa nangokuthi ikhampasi, i-Chinese Transliteration: Beidou) uhlelo lomkhumbi wokuzulazula we-satellite olwenziwe ngokuzimela ngeChina. Yisistimu yesithathu yokuvukela ye-satellite navigation elandela i-GPS ne-Glonass.

Beidou Generation I

Ukwabiwa kwe-Frequency Band of Beidou Generation ngikuhilela ukunqunywa kwe-Satellite Service (RDSS) amabhendi we-Radio (i-RDSS), ngokuhlukaniswa ngokukhethekile kube amabhande akhuphukayo namabhande aphansi:
a) I-Plink Band: Leli bandla lisetshenziselwa imishini yomsebenzisi ukudlulisa amasiginali kuma-satellites, ngobubanzi be-1610mhz kuya ku-1626.5mhz, nge-L-band. Lo mklamo we-band uvumela imishini yomhlaba ukuthumela izicelo zokubeka kanye neminye imininingwane efanelekile kuma-satellites.
b) I-Downlink Band: Leli bandla lisetshenziselwa ama-satellites ukuhambisa amasiginali kwimishini yomsebenzisi, ngobubanzi bama-2483.5mhz kuya ku-2500mhhz, nge-S-band. Lo mklamo we-band unika amandla ama-satellite ukuhlinzeka ngemininingwane yokuhambisa, idatha yokubeka isikhundla, nezinye izinsizakalo ezidingekayo emishini yomhlaba.
Kuyaphawuleka ukuthi ukwabiwa kwale bhendi imvamisa ye-beidou Generation ngangenzelwe ngokuyinhloko ukufeza izidingo zobuchwepheshe nokubeka izidingo zokunemba ngaleso sikhathi. Ngokuthuthuka kwezobuchwepheshe kanye nokuthuthuka okuqhubekayo ohlelweni lweBeidou, izizukulwane ezalandela, kufaka phakathi i-Beidou Generation II kanye ne-III, izindlela zokushintshanisa zokushintshanisa ukuhlinzeka ngokunemba okuphezulu nokubeka izinsiza ezithembekile kanye nezinsizakalo zokubeka izinto ezithembekile.

Beidou Generation II

I-Beidou Generation II, uhlelo lwesizukulwane sesibili se-Beidou navigation Satellite System (BDS), uhlelo olutholakala emhlabeni jikelele olutholakala emhlabeni we-satellite navigation otholakala ngokuzimela yiChina. Ukwakha phezu kwesisekelo se-Beidou Generation I, kuhlose ukuhlinzeka ngokunemba okuphezulu, ukuma okuthe xaxa okuphezulu, ukuzulazula, kanye nezinsizakalo zesikhathi (PNT) kubasebenzisi emhlabeni wonke. Uhlelo lolu lunezingxenye ezintathu: isikhala, umhlabathi, kanye nomsebenzisi. Ingxenye yesikhala ifaka ama-satellite amaningi wokuhambisa, ingxenye yenhlabathi ifaka iziteshi zokulawula, iziteshi zokuqapha, kanye neziteshi ze-uplink, ngenkathi ingxenye yomsebenzisi inamadivayisi ahlukahlukene ahlukahlukene.
Ukwabiwa kwe-Frequency Band of Beidou Generation II ngokuyinhloko kubandakanya amabhendi amathathu: B1, B2, kanye ne-B3, ngamapharamitha athile ngale ndlela elandelayo:
a) B1 Band: Ububanzi be-Frequency Ububanzi be-1561.098mhz ± 2.046mhz, ngokuyinhloko esetshenziselwa ukuzulazula kwezehlakalo kanye nezinsizakalo zokubeka isikhundla.
b) B2 Band: Ububanzi be-1207.52mhz ± 2.046mhz, futhi ngokuyinhloko basetshenziselwa izinsizakalo zezempi, ukusebenza kanye ne-B1 band ukuhlinzeka ngamakhono okuma kwemva kokukhulisa okuthuthukile.
c) B3 Band: Ububanzi be-Frequency Ububanzi be-1268.52mhz ± 10.23mhz, ngokuyinhloko esetshenziselwa amasosha, enikeza ukunemba okuphezulu nokulwa nokulwa nokuphazamiseka.

Beidou Generation III

Uhlelo lwe-Beidou navigation lwesithathu, nangokwaziwa ngokuthi i-Beidou-3 Global Navigation Navigation System System, uhlelo olutholakala emhlabeni jikelele we-satellite navigation sakhiwe ngokuzimela futhi isebenza yiChina. Ithole i-leap kusuka esifundeni ukusembozwa komhlaba wonke, ukuhlinzeka ngokunemba okuphezulu, ukuma okuthe xaxa okuphezulu, ukuzulazula, kanye nezinsizakalo zesikhathi kubasebenzisi emhlabeni wonke. IBeidou-3 inikeza amasiginali wesevisi avulekile amaningi kuwo wonke amabhendi we-B1, B2, nama-B3, kufaka i-B1I, B1C, B2A, B2B, kanye neB3I. Ukunikezwa imvamisa yalezi zimpawu kungokulandelayo:
a) B1 Band: B1I: ​​Imvamisa yesikhungo se-1561.098mhz ± 2.046mhz, isibonakaliso esiyisisekelo esisetshenziswe kabanzi kumadivayisi ahlukahlukene wokuhambisa; I-B1C: Imvamisa yesikhungo se-1575.420mhz ± 16MHZ, isiginali esiyinhloko isekela ama-beidou-3 m / i-satellites futhi asekelwa ama-terminals amasha, aphela.
b) B2 Band: B2A: Imvamisa yesikhungo se-1176.450mhz ± 10.23MHZ, futhi nesiginali eyisisekelo esekela ama-beidou-3 m / ama-satellites ama-satellite asezingeni eliphakeme, aphela; I-B2B: Imvamisa yesikhungo se-1207.140mhz ± 10.23MHZ, isekela ama-satellites we-Beidou-3 m / i-i-satellites kodwa atholakala kuphela ku-Select End terminals.
c) B3 Band: B3I: Imvamisa yesikhungo se-1268.520mhz ± 10.23mhz, esekelwa yiwo wonke ama-satellites kuwo womabili ama-Beidou Generation II ne-III, ngokuxhaswa kwama-multi-frequency module.

I-Chengdu Concept Microwave Technology Co., I-Ltd ingumenzi ochwepheshe wezakhi ze-5G / 6G RFingomaneUkuxhumana kwe-Satellite eChina, kufaka phakathi isihlungi se-RF LowPass, isihlungi esingu-HigPass, isihlungi se-bandpass, isihlungi se-bandch / i-band stop clep, i-coupler eqondile kanye ne-coupler eqondile. Zonke zingenziwa ngokwezifiso ngokuya ngokwalokho okuvuselelayo kwakho.
