Ko te tūnga kinematic wā-tūturu (RTK) he tikanga e whakatika ana i ngā hapa noa i roto i ngā pūnaha whakatere amiorangi o nāianei (GNSS). Haunga ngā ihirangi mōhiohio o te tohu, ka whakamahia hoki te uara ine o te wāhanga kawe tohu, ā, ka whakawhirinaki ki tētahi teihana tohutoro kotahi, ki tētahi teihana mariko whakauru rānei hei whakarato i ngā whakatikatika wā-tūturu, e whakarato ana i te tika tae atu ki te taumata henimita.
TakitahiSte RTK o te teihana
Ko te momo ine RTK māmā rawa atu ka mahia mā te āwhina o ngā kaiwhiwhi RTK e rua, e kiia nei ko te teihana kotahi RTK. I roto i te teihana kotahi RTK, ka whakatūria he kaiwhiwhi tohutoro ki runga i tētahi pūwāhi me te tūranga e mōhiotia ana, ā, ka whakatakotoria he rover (kaiwhiwhi neke) ki runga i ngā pūwāhi e whakatauhia ana te tūranga. Mā te whakamahi i te tūranga whanaunga, ka whakakotahi te rover i āna ake tirohanga GNSS me te teihana tohutoro hei whakaiti i ngā pūtake hapa, kātahi ka whiwhi i te tūranga. Ko te tikanga o tēnei me mātakitaki te teihana tohutoro me te rover i te rōpū kotahi o ngā amiorangi GNSS i te wā kotahi, ā, ka taea e te hononga raraunga te tuku i te tūranga me ngā hua tirohanga o te teihana tohutoro ki te teihana rover i te wā tūturu.
Whatunga RTK (NRTK)
I tēnei wā, kei te otinga RTK tētahi whatunga o ngā teihana tohutoro kei a ia anō, e āhei ai te kaiwhiwhi kaiwhakamahi ki te hono atu ki tētahi teihana tohutoro mā te whai i te kaupapa kotahi. Ina whakamahia te whatunga teihana tohutoro, ka nui ake te kapinga o te otinga RTK.
Mā te whatunga o ngā teihana tohutoro, ka taea te whakatauira i ngā hapa e pā ana ki te tawhiti me te tika ake. I runga i tēnei tauira, ka tino whakaitihia te whakawhirinakitanga ki te tawhiti ki te pūihi tata. I roto i tēnei tatūnga, ka hangaia e te ratonga he Teihana Tohutoro Mariko (VRS) e tata ana ki te kaiwhakamahi, e whakatauira ana i ngā hapa i te tūranga o te kaiwhiwhi kaiwhakamahi. I te nuinga o te wā, ka whakaratohia e tēnei tikanga he whakatikatika pai ake i te rohe ratonga katoa, ā, ka taea e te whatunga teihana tohutoro te iti ake te matotoru. Ka whakaratohia hoki he pono ake nā te mea he iti ake te whakawhirinaki ki tētahi teihana tohutoro kotahi.
I roto i te poto, mā te whakamahi i ngā tikanga ine hei whakatika i ngā hapa i roto i ngā pūnaha whakatere amiorangi, ka whakatuwherahia e te RTK te huarahi mō te hangarau GNSS ki te whakatutuki i te tika taumata-henimita. Nā te tino tika o te RTK he mea pai mō ngā kaupapa ahumahi maha, tae atu ki te ahuwhenua, te keri me te whanaketanga hanganga. I roto i ēnei ahumahi, he mea nui te tūnga tika mō te angitu. Hei tauira, mā te whakarite kia tika te whakatinanatanga o ngā mahi ahuwhenua, ka taea e ngā kaimahi pāmu te whakapai ake i te whai huatanga o te mahi. Ehara i te mea ka whakanui noa i ngā hua o te hua, engari ka arotau hoki i te whakamahinga o ngā rauemi pēnei i ngā maniua me te wai, ā, ka penapenahia te utu me te hanga tikanga ahuwhenua pumau ake.
Kei te tautokohia e 3Rtablet te kōwae RTK kua hangaia i roto i te papa AT-10A hou, e whakapai ake ana i te mahi a te papa i roto i ngā āhuatanga tono rerekē me ngā āhuatanga mahi uaua. Mā te uru atu ki ngā raraunga tūnga tino tika i runga i ngā taputapu kawe, ka taea e ngā tohunga o ngā āhuatanga katoa te mahi i ngā mahi mara me te ngāwari me te tika.
