Ko te Pūnaha Tiritiri Whakatere Beidou (BDS, e mōhiotia ana ko COMPASS, te whakamaoritanga Hainamana: BeiDou) he pūnaha whakatere amiorangi o te ao i whakawhanakehia motuhaketia e Haina. Ko te tuatoru o ngā pūnaha whakatere amiorangi kua pakari i muri i te GPS me te GLONASS.
Te Whakatipuranga Tuatahi o Beidou
Ko te tohatoha o te roopu auau o te Beidou Reanga Tuatahi e pā ana ki ngā roopu Ratonga Whakatau Amiorangi Reo Irirangi (RDSS), e wehea ana ki ngā roopu hononga-ake me ngā roopu hononga-iho:
a) Roopu Hononga-ake: Ka whakamahia tēnei roopu mō ngā taputapu kaiwhakamahi hei tuku tohu ki ngā amiorangi, me te awhe auau o te 1610MHz ki te 1626.5MHz, nō te roopu-L. Mā tēnei hoahoa roopu ka taea e ngā taputapu whenua te tuku tono tūnga me ētahi atu mōhiohio e tika ana ki ngā amiorangi.
b) Roopu Hononga-ki-raro: Ka whakamahia tēnei roopu mō ngā amiorangi hei tuku tohu ki ngā taputapu kaiwhakamahi, me te awhe auau o te 2483.5MHz ki te 2500MHz, nō te roopu-S. Mā tēnei hoahoa roopu ka taea e ngā amiorangi te whakarato i ngā mōhiohio whakatere, ngā raraunga tūnga, me ētahi atu ratonga e tika ana ki ngā taputapu whenua.
He mea nui kia mōhiotia ko te tohatoha o te roopu auau o te Whakatipuranga Tuatahi o Beidou i hangaia tuatahitia kia tutuki ai ngā whakaritenga hangarau me ngā tono tika o te tūnga o taua wā. Nā te whanaketanga hangarau me ngā whakahoutanga tonu o te pūnaha Beidou, i whakamahia e ngā whakatipuranga o muri mai, tae atu ki te Whakatipuranga Tuarua me te III o Beidou, ngā roopu auau rerekē me ngā tikanga whakarerekētanga tohu hei whakarato i ngā ratonga whakatere me te tūnga tino tika me te pono ake.
Beidou Whakatipuranga II
Ko te Beidou Generation II, te pūnaha tuarua o te whakatupuranga o te Beidou Navigation Amiorangi System (BDS), he pūnaha whakatere amiorangi e wātea ana ki te ao katoa i whakawhanakehia motuhaketia e Haina. I runga i te turanga o Beidou Generation I, ko tana whāinga he whakarato i ngā ratonga tūnga, whakatere, me te wā (PNT) tino tika, tino pono hoki ki ngā kaiwhakamahi o te ao. E toru ngā wāhanga o te pūnaha: te wāhi, te whenua, me te kaiwhakamahi. Kei roto i te wāhanga wāhi he maha ngā amiorangi whakatere, ko te wāhanga whenua kei roto ko ngā teihana whakahaere matua, ngā teihana aroturuki, me ngā teihana hononga-ake, ko te wāhanga kaiwhakamahi kei roto ko ngā taputapu whiwhi maha.
Ko te tohatoha o te roopu auau o Beidou Reanga II e kapi ana i ngā roopu e toru: B1, B2, me B3, me ngā tawhā motuhake penei:
a) B1 Band: Awhe auau o 1561.098MHz ± 2.046MHz, e whakamahia ana mō ngā ratonga whakatere me te tūnga ā-iwi.
b) Te Rōpū B2: Te whānuitanga auau o te 1207.52MHz ± 2.046MHz, e whakamahia ana hoki mō ngā ratonga ā-iwi, e mahi tahi ana me te rōpū B1 hei whakarato i ngā āheinga tūnga auau-rua mō te whakapai ake i te tika o te tūnga.
c) B3 Band: Awhe auau o te 1268.52MHz ± 10.23MHz, e whakamahia ana mō ngā mahi hōia, e tuku ana i te tika o te tūnga me ngā āheinga ārai-whakararuraru teitei ake.
Beidou Whakatipuranga III
Ko te Pūnaha Whakatere Beidou o te tuatoru o ngā whakatipuranga, e mōhiotia ana ko te Pūnaha Amiorangi Whakatere Ao Beidou-3, he pūnaha whakatere amiorangi e taea ai te uru atu ki te ao katoa i hangaia motuhaketia, ā, i whakahaerehia hoki e Haina. Kua eke ki tētahi peke mai i te kapinga ā-rohe ki te ao whānui, e whakarato ana i ngā ratonga tūnga, whakatere, me te wā tino tika, tino pono hoki ki ngā kaiwhakamahi o te ao katoa. He maha ngā tohu ratonga tuwhera a Beidou-3 puta noa i ngā roopu B1, B2, me B3, tae atu ki te B1I, B1C, B2a, B2b, me te B3I. Ko ngā tohatoha auau o ēnei tohu e whai ake nei:
a) B1 Band: B1I: Auautanga pokapū o 1561.098MHz ± 2.046MHz, he tohu taketake e whakamahia whānuitia ana i roto i ngā momo taputapu whakatere; B1C: Auautanga pokapū o 1575.420MHz ± 16MHz, he tohu matua e tautoko ana i ngā amiorangi Beidou-3 M/I, ā, e tautokona ana e ngā pūwhakatere pūkoro hou ake, teitei.
b) B2 Band: B2a: Auautanga pokapū o 1176.450MHz ± 10.23MHz, he tohu matua hoki e tautoko ana i ngā amiorangi Beidou-3 M/I, ā, e wātea ana i runga i ngā pūwhakawhiti waea hou ake, teitei; B2b: Auautanga pokapū o 1207.140MHz ± 10.23MHz, e tautoko ana i ngā amiorangi Beidou-3 M/I engari e wātea ana i runga i ētahi pūwhakawhiti waea teitei anake.
c) Roopu B3: B3I: Auautanga pokapū o 1268.520MHz ± 10.23MHz, e tautokona ana e ngā amiorangi katoa i roto i te Whakatipuranga II me te III o Beidou, me te tautoko pai mai i ngā kōwae maha-aratau, maha-auautanga.
