Ukuma kwe-kinematic yesikhathi sangempela (RTK): Umsizi onamandla wokuthuthukisa ukunemba komsebenzi wezimboni

I-Real-time kinematic positioning (RTK) yindlela elungisa amaphutha ajwayelekile kuzinhlelo zamanje ze-satellite navigation navigation (GNSS). Ngaphezu kokuqukethwe kolwazi kwesiginali, futhi isebenzisa inani elilinganisiwe lesigaba se-Signal Carriers, futhi lithembele esiteshini esisodwa noma esiteshini sokuhumusha ukuhlinzeka ngokunemba kwesikhathi sangempela, ukuhlinzeka ngokunemba kuze kube yilapho kufika ezingeni lesentimitha.

-Nye zwiStation rtk

Ifomu elilula lokulinganisa le-RTK lenziwa ngosizo lwabathola ababili be-RTK, olubizwa ngokuthi isiteshi esisodwa RTK. Esitebelweni esisodwa se-RTK, isitholi sereferensi simiswa ngaphezulu kwephuzu ngesikhundla esaziwayo kanye ne-rover (owemukelayo) sibekwe ngaphezulu kwamaphoyinti azonqunywa. Kusetshenziswa isikhundla esihlobene, i-rover ihlanganisa ukubonwa kwayo kwe-GNSS nesiteshi sereferensi ukunciphisa imithombo yephutha bese ithola isikhundla. Lokhu kudinga ukuthi isiteshi sereferensi kanye ne-rover siqaphele iqembu elifanayo lama-satellite afanayo we-GNSS ngasikhathi sinye, futhi isixhumanisi sedatha singadlulisela isikhundla nokubhekwa kwesiteshi sereferensi esiteshini seRover ngesikhathi sangempela.

Inethiwekhi RTK (NRTK)

Kulokhu, isixazululo se-RTK sinenethiwekhi yeziteshi zamareferensi ezazinawo anazo, ezivumela umsebenzisi owemukelayo ukuthi axhumeke kunoma yisiphi isithenjwa ngokulandela umgomo ofanayo. Lapho usebenzisa iziteshi zesethenjwa, ukumbozwa kwesixazululo se-RTK kuzokhuphuka kakhulu.

Ngenethiwekhi yeziteshi zokubhekisisa, kungenzeka ukuthi uhlole amaphutha ancike ekude kakhulu. Ngokusekelwe kule modeli, ukuncika ebangeni ukuya e-antenna eseduze kuncishiswe kakhulu. Kulesi sethaphu, insizakalo idala isiteshi esibonakalayo sereferensi (VRS) eduze komsebenzisi, empeleni imodeli amaphutha esikhundleni somukeli lomsebenzisi. Ngokuvamile, le ndlela ihlinzeka ngokulungiswa okungcono endaweni yonke yenkonzo futhi ivumela inethiwekhi yesiteshi sereferensi ukuze sibe mnene. Inikeza nokuthembela okungcono ngoba incike kancane esiteshini esisodwa sereferensi.

Ngamafuphi, ngokusebenzisa amasu wokulinganisa ukulungisa amaphutha ku-Satellite Navigation Systems, i-RTK ivula amathuba okuba ubuchwepheshe be-GNSS ukufezekisa ukunemba kweleveli ye-GNSS. Ukunemba okuhle kwe-RTK kwenza kube yikhetho oluhle kumaphrojekthi amaningi wezimboni, kubandakanya ezolimo, ukulimala kwezimayini kanye nokuthuthukiswa kwengqalasizinda. Kulezi zimboni, ukuma okunembile kubalulekile empumelelweni. Ukuthatha ezolimo njengesibonelo, ngokuqinisekisa ukuqaliswa okunembile kwemisebenzi yezolimo, abalimi bangathuthukisa ukusebenza kahle. Lokhu akugcini nje kukhulisa izivuno zezitshalo, kepha futhi nokwenza kahle ukusetshenziswa kwezinsizakusebenza njengamanyolo namanzi, ngaleyo ndlela kulungiswa izindleko nokwakha izindlela zokulima ezinzile.

I-3RAblet manje isekela inketho ye-RTK eyakhelwe ngaphakathi kwe-RTK kwithebhulethi yakamuva ku-10a, okuqhubeka nokuthuthukisa ukusebenza kwethebhulethi kwizimo ezihlukile zohlelo lokusebenza kanye nezimo zokusebenza ezinokhahlo. Ngokuthola idatha enembile kakhulu kumadivayisi aphathekayo, ochwepheshe abavela kuzo zonke izindlela zokuphila bangakwenza kalula futhi ngokunembile umsebenzi wensimu.
