A Beidou akuyenda ma statellite system (BDS, omwe amadziwikanso kuti COMPASS, Translizetion China: Beidou) ndi njira yapadziko lonse yomwe idakhazikitsidwa ndi China. Ndiwo ma satellite a Natellite Nativestem yotsatira gps ndi glonass.
Beidou m'badwo ine
Gawo la band pafupipafupi lomwe limaphatikizaponso ma radionce a radio (RDSS) okhazikika, omwe amagawika m'magulu am'munsi komanso am'munsi:
A) Uplink Band: Bandi ili limagwiritsidwa ntchito kwa zida za ogwiritsa ntchito kuti zigawire zizindikiro kwa Satellites, ndi mitundu yonse ya 1610.5mhz mpaka 1626.5mz, gulu la L -B. Mapangidwe awa amalola zida za pansi kuti zitumize zopempha ndi zina zofunika kuzinthu.
b) Domlink band: Bandi ili limagwiritsidwa ntchito kwa satellites kuti apereke zizindikiro kwa zida zosuta, ndi mndandanda wa 2483.5mhz mpaka 2500mhz, a s-band. Mapangidwe awa amathandizira Satellites kuti apereke chidziwitso cha panyanja, kuyika deta, ndi ntchito zina zofunika ku zida zapakhomo.
Ndizofunikira kudziwa kuti kuchuluka kwa gulu lazithunzi za Beidou m'badwo wa Beidou ndidapangidwa kuti ndikwaniritse zofunikira zaukadaulo ndikugwiritsa ntchito zolondola nthawi imeneyo. Ndi kupita patsogolo kwa ukadaulo komanso kusintha kosalekeza kwa mibadwo ya Beidou, mibadwo yotsatira, kuphatikizapo Iidou atsogoleri a II ndi iii, njira zosiyanasiyana zosinthira kuyenda bwino komanso ntchito zodalirika.
Beidou Earth II
Beidou apainiya, kalikonse ka mudzi wachiwiri wa Iidou Navi yoyendetsa Satellite System (BDS), ndi njira yolowera padziko lonse lapansi yopangidwa ndi China. Kumanga pa maziko a m'badwo wa Beidou m'badwo wa Beidou, zikufuna kuperekera molingana kwambiri, kudalirika kwakukulu, kuyenda, ndi nthawi (ma PT) kwa ogwiritsa ntchito padziko lonse lapansi. Dongosolo limakhala magawo atatu: danga, nthaka, ndi wosuta. Mbali ya danga imaphatikizapo ma satelgi oyenda panyanja, malo oyang'anira nthaka amawongolera master
Kugawidwa pafupipafupi kwa Ii Miyezi itatuikulu ku Stedoud Atatu: B1, B2, B2, ndi B3, ndi magawo ena motere:
A) B1 Bandi: Kuchuluka kwa 1561.098Mz ± 2.046mhz, makamaka komwe kumagwiritsidwa ntchito pankhondo ya anthu wamba komanso ntchito zina.
b) B2 Band: Miyezo yonse ya 1207.52Mz ± 2.046Mz ± 2.046mhz, yemwenso amagwiritsidwa ntchito makamaka pantchito zapadziko lonse lapansi kuti zithetse kulondola.
c) B3 gulu: Mitundu yonse ya 1268.52Mz ± 10.23Mz ±
Beidou atsogoleri iii
Katswiri wam'badwo wa mibadwo yachitatu, yomwe imadziwikanso kuti Beidou-3 National Naving Systems, ndi njira yolowera padziko lonse lapansi yopangidwa ndi China. Zakwaniritsa kudumphadumpha kuchokera kudera kuti zitheke, ndikupereka chidziwitso chokwanira kwambiri, chodalirika kwambiri, kuyenda, ndi ntchito yoyenda ndi nthawi kwa ogwiritsa ntchito padziko lonse lapansi. Beidou-3 imapereka zizindikiro zingapo zotseguka kudutsa B1, B2, ndi magulu a B3C, B1C, B1C, B3B, ndi B3I. Kupereka kwatsatanetsatane kwa zizindikirozi ndi motere:
a) B1 Band: B1i: Center pafupipafupi wa 1561.098Mz ± 2.046mhz, chizindikiro choyambirira chogwiritsidwa ntchito munkhondo zosiyanasiyana; B1C: Center pafupipafupi wa 1575.420mhz ± 16mhz, choyambirira chothandizira bedou-3 m / ine ndikuchirikiza matebulo omaliza.
b) B2 Band: B2a: Center pafupipafupi wa 1176.450mhz ± 10.23mhz, komanso ma satelites omwe amathandizidwa ndi mafoni apamwamba; B2B: Pakatikati pa 1207.140mhz ± 10.23mhz, othandizira beidou-3 m / ine satellites pokhapokha posankha mafoni apamwamba kwambiri.
c) B3 BOB: B3i: Pakatikati pa 1268.50Mzz ± 2620mz ±
Chengdu netchrology Technology Countlogy Co., Ltd ndi wopanga akatswiri a 5G / 6g rfwaKuyankhulana za Satellite ku China, kuphatikizapo phweka ya RF Flowspass, tepposs sfee, svasel over / bapler spesetor, storter skefrion ndi njira yoyendetsera. Zonsezi zimatha kusinthidwa molingana ndi zomwe mukufuna.
