Sisitimu yekufamba nesatellite yeBeidou (BDS, inozivikanwawo seCOMPASS, shanduro yechiChinese: BeiDou) sisitimu yekufamba nesatellite yepasi rose yakagadzirwa yakazvimirira neChina. Ndiyo sisitimu yechitatu yakakura yekufamba nesatellite ichitevera GPS neGLONASS.
Chizvarwa cheBeidou I
Kugoverwa kwemabhendi emafrequency eBeidou Generation I kunonyanya kusanganisira mabhendi eRadio Determination Satellite Service (RDSS), akakamurwa kuva mabhendi euplink nedownlink:
a) Uplink Band: Iyi bhendi inoshandiswa pamidziyo yemushandisi kutumira masaini kumasetiraiti, ine frequency range ye1610MHz kusvika 1626.5MHz, iri yeL-band. Dhizaini iyi yebhendi inobvumira michina yepasi kutumira zvikumbiro zvekuisa uye rumwe ruzivo rwakakosha kumasetiraiti.
b) Downlink Band: Iyi bhendi inoshandiswa kumasetiraiti kutumira masaini kumidziyo yemushandisi, ine frequency range ye2483.5MHz kusvika 2500MHz, iri yeS-band. Dhizaini iyi yebhendi inogonesa masetiraiti kupa ruzivo rwekufamba, data rekuisa, uye mamwe mabasa anodiwa kumidziyo yepasi.
Zvinokosha kuziva kuti kugoverwa kwebhendi yemafrequency yeBeidou Generation I kwakagadzirwa zvakanyanya kuti kusangane nezvinodiwa zvehunyanzvi uye zvinodiwa zvekugadzirisa nzvimbo panguva iyoyo. Nekufambira mberi kwetekinoroji uye kuvandudzwa kuri kuitwa kune sisitimu yeBeidou, zvizvarwa zvakatevera, kusanganisira Beidou Generation II neIII, zvakatora nzira dzakasiyana dzekugadzirisa mafrequency uye nzira dzekuchinja masignal kuti zvipe masevhisi ekufambisa nekuisa nzvimbo akanyatsojeka uye akavimbika.
Chizvarwa cheBeidou II
Beidou Generation II, sisitimu yechizvarwa chechipiri cheBeidou Navigation Satellite System (BDS), sisitimu yekufamba nesatellite inowanikwa pasi rose yakagadzirwa neChina yakazvimirira. Ichivakira pahwaro hweBeidou Generation I, ine chinangwa chekupa masevhisi ePNT akanyatsojeka, akavimbika, uye akavimbika kune vashandisi pasi rese. Sisitimu iyi ine zvikamu zvitatu: nzvimbo, pasi, uye mushandisi. Chikamu chenzvimbo chinosanganisira masatellite akawanda ekufamba, chikamu chepasi chinosanganisira nzvimbo huru dzekudzora, nzvimbo dzekutarisa, uye nzvimbo dzeuplink, nepo chikamu chemushandisi chiine zvishandiso zvakasiyana-siyana zvekugamuchira.
Kugoverwa kwemabhendi efrequency eBeidou Generation II kunonyanya kusanganisira mabhendi matatu: B1, B2, uye B3, nematanho chaiwo anotevera:
a) B1 Band: Frequency range ye1561.098MHz ± 2.046MHz, inonyanya kushandiswa pakufambisa nekuisa nzvimbo dzevanhuwo zvavo.
b) B2 Band: Frequency range ye1207.52MHz ± 2.046MHz, inonyanya kushandiswa pamabasa ehurumende, ichishanda pamwe chete neB1 band kupa kugona kwekuisa mafrequency maviri kuti ive neruzivo rwakanyanya pamusoro penzvimbo.
c) B3 Band: Frequency range ye1268.52MHz ± 10.23MHz, inonyanya kushandiswa kumabasa emauto, ichipa kugona kwepamusoro kwekuisa nzvimbo uye kugona kudzivirira kukanganiswa.
Chizvarwa cheBeidou III
Sisitimu yeBeidou Navigation System yechizvarwa chechitatu, inozivikanwawo seBeidou-3 Global Navigation Satellite System, isystem yekufamba nesatellite inowanikwa pasi rose yakagadzirwa uye inoshandiswa neChina yakazvimirira. Yakabudirira kubva pakukura kwenzvimbo kuenda pasi rose, ichipa masevhisi ekuisa nzvimbo, kufamba, uye nguva kune vashandisi pasi rese. Beidou-3 inopa masaini akawanda ebasa rakavhurika mumabhendi eB1, B2, uye B3, anosanganisira B1I, B1C, B2a, B2b, uye B3I. Kugoverwa kwemasaini aya kwakafanana neizvi:
a) B1 Band: B1I: Frequency yepakati ye1561.098MHz ± 2.046MHz, chiratidzo chepakutanga chinoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yekufambisa; B1C: Frequency yepakati ye1575.420MHz ± 16MHz, chiratidzo chekutanga chinotsigira satellite dzeBeidou-3 M/I uye chinotsigirwa nematerminal matsva efoni epamusoro-soro.
b) B2 Band: B2a: Frequency yepakati ye1176.450MHz ± 10.23MHz, zvakare chiratidzo chikuru chinotsigira masatellite eBeidou-3 M/I uye chinowanikwa pamaterminal matsva enharembozha; B2b: Frequency yepakati ye1207.140MHz ± 10.23MHz, inotsigira masatellite eBeidou-3 M/I asi inowanikwa chete pamaterminal enharembozha epamusoro-soro.
c) B3 Band: B3I: Frequency yepakati ye1268.520MHz ± 10.23MHz, inotsigirwa nemasatellite ese ari muBeidou Generation II neIII, nerutsigiro rwakanaka kubva kumamodule emulti-mode, multi-frequency.
Chengdu Concept Microwave Technology CO., Ltd inyanzvi yekugadzira zvikamu zve5G/6G RFyekutaurirana nesatellite muChina, kusanganisira RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider uye directional coupler. Zvese zvinogona kugadziriswa zvichienderana nezvaunoda.
