Moloko oa Beidou I
Kabo ea sehlopha sa maqhubu a Beidou Generation I e kenyeletsa haholo-holo lihlopha tsa Radio Determination Satellite Service (RDSS), tse arotsoeng ka ho khetheha ka lihlopha tsa uplink le downlink:
a) Lebanta la Uplink: Lebanta lena le sebedisetswa disebediswa tsa mosebedisi ho fetisetsa matshwao ho disathelaete, ka maqhubu a 1610MHz ho isa ho 1626.5MHz, a leng a lebanta la L. Moralo ona wa lebanta o dumella disebediswa tsa fatshe ho romela dikopo tsa ho beha le tlhahisoleseding e nngwe e amehang ho disathelaete.
b) Lebanta la Downlink: Lebanta lena le sebedisetswa disathelaete ho fetisetsa matshwao ho disebediswa tsa mosebedisi, ka maqhubu a 2483.5MHz ho isa ho 2500MHz, a leng a sehlopha sa S. Moralo ona wa lebanta o thusa disathelaete ho fana ka tlhahisoleseding ya ho tsamaya, data ya ho beha, le ditshebeletso tse ding tse hlokahalang ho disebediswa tsa fatshe.
Hoa hlokomeleha hore kabo ea sehlopha sa maqhubu a Beidou Generation I e ne e etselitsoe haholo-holo ho fihlela litlhoko tsa tekheniki le litlhoko tsa ho nepahala ha ho beha maemo tsa nako eo. Ka tsoelo-pele ea theknoloji le ntlafatso e tsoelang pele tsamaisong ea Beidou, meloko e latelang, ho kenyeletsoa le Mofuta oa Beidou II le oa III, e ile ea amohela lihlopha tse fapaneng tsa maqhubu le mekhoa ea ho fetola matšoao ho fana ka lits'ebeletso tsa ho tsamaea le ho beha maemo tse nepahetseng haholoanyane le tse tšepahalang haholoanyane.
Moloko oa Beidou II
Moloko oa Beidou II, sistimi ea moloko oa bobeli oa Sistimi ea Sathelaete ea Beidou Navigation (BDS), ke sistimi ea ho tsamaisa sathelaete e fumanehang lefatšeng ka bophara e ntlafalitsoeng ka boikemelo ke Chaena. Ha e hahuoa motheong oa Moloko oa Beidou I, e ikemiselitse ho fana ka lits'ebeletso tse nepahetseng haholo, tse tšepahalang haholo tsa ho beha, ho tsamaisa, le nako (PNT) ho basebelisi lefatšeng ka bophara. Sistimi ena e na le likarolo tse tharo: sebaka, mobu le mosebelisi. Karolo ea sebaka e kenyelletsa li-satellite tse ngata tsa ho tsamaisa, karolo ea mobu e kenyelletsa liteishene tse kholo tsa taolo, liteishene tsa ho beha leihlo le liteishene tsa uplink, ha karolo ea mosebelisi e kenyelletsa lisebelisoa tse fapaneng tsa ho amohela.
Kabo ea sehlopha sa maqhubu sa Beidou Generation II e akaretsa haholo-holo lihlopha tse tharo: B1, B2, le B3, ka liparamente tse ikhethileng tse latelang:
a) Lebanta la B1: Methati ya maqhubu ke 1561.098MHz ± 2.046MHz, e sebediswang haholoholo bakeng sa ditshebeletso tsa ho tsamaya le ho beha batho sebakeng sa bona.
b) Sehlopha sa B2: Mefuta ya maqhubu a 1207.52MHz ± 2.046MHz, hape e sebediswa haholoholo bakeng sa ditshebeletso tsa baahi, e sebetsa mmoho le sehlopha sa B1 ho fana ka bokgoni ba ho beha maqhubu a mabedi bakeng sa ho nepahala ho ntlafaditsweng ha sebaka.
c) Lebanta la B3: Methati ya maqhubu ke 1268.52MHz ± 10.23MHz, e sebediswang haholoholo bakeng sa ditshebeletso tsa sesole, e fanang ka ho nepahala ho hoholo ha maemo le bokgoni ba ho thibela tshitiso.
Moloko oa Boraro oa Beidou
Sistimi ea ho Tsamaea ea Beidou ea moloko oa boraro, e tsejoang hape e le Sistimi ea Satellite ea ho Tsamaea ea Lefatše ea Beidou-3, ke sistimi ea ho tsamaea ea sathelaete e fumanehang lefatšeng ka bophara e hahiloeng le ho tsamaisoa ke Chaena ka boikemelo. E fihletse phetoho ho tloha sebakeng se seng ho ea ho se akaretsang sa lefats'e, e fana ka lits'ebeletso tsa ho beha maemo, ho tsamaea le nako tse nepahetseng haholo ho basebelisi lefatšeng ka bophara. Beidou-3 e fana ka matšoao a mangata a tšebeletso e bulehileng ho pholletsa le lihlopha tsa B1, B2, le B3, ho kenyeletsoa B1I, B1C, B2a, B2b, le B3I. Kabo ea makhetlo a matšoao ana ke a latelang:
a) Lebanta la B1: B1I: Maqhubu a bohareng a 1561.098MHz ± 2.046MHz, lets'oao la motheo le sebelisoang haholo lisebelisoa tse fapaneng tsa ho tsamaea; B1C: Maqhubu a bohareng a 1575.420MHz ± 16MHz, lets'oao la mantlha le tšehetsang lisathelaete tsa Beidou-3 M/I le tšehetsoang ke li-terminal tse ncha, tse phahameng tsa mehala.
