I-Real-time Kinematic Positioning (RTK): Umsizi Onamandla Wokuthuthukisa Ukunemba Komsebenzi Wezimboni

I-Real-time kinematic positioning (RTK) iyindlela elungisa amaphutha avamile ezinhlelweni zamanje zokuzulazula ngesathelayithi (GNSS). Ngokungeziwe kokuqukethwe kolwazi lwesignali, iphinda isebenzisa inani elilinganiselwe lesigaba senkampani yenethiwekhi, futhi ithembele esiteshini esisodwa sereferensi noma isiteshi esibonakalayo sokuhumusha ukuze sinikeze izilungiso zesikhathi sangempela, sinikeze ukunemba kuze kufike ezingeni lesentimitha.

AwushadileSintengo RTK

Ifomu lokulinganisa le-RTK elilula lenziwa ngosizo lwabamukeli ababili be-RTK, okubizwa ngesiteshi esisodwa i-RTK. Ku-RTK yesiteshi esisodwa, isamukeli sereferensi simiswa phezu kwephuzu elinendawo eyaziwayo futhi i-rover (isamukeli esinyakazayo) ibekwe phezu kwamaphoyinti okumele kunqunywe indawo yawo. Isebenzisa ukuma okuhlobene, i-rover ihlanganisa ukubonwa kwayo kwe-GNSS nesiteshi sereferensi ukuze kuncishiswe imithombo yephutha bese ithola isikhundla. Lokhu kudinga ukuthi isiteshi sereferensi kanye ne-rover zibheke iqembu elifanayo lamasathelayithi e-GNSS ngesikhathi esifanayo, futhi isixhumanisi sedatha singadlulisela isimo nemiphumela yokubhekwa kwesiteshi sereferensi esiteshini se-rover ngesikhathi sangempela.

Inethiwekhi ye-RTK (NRTK)

Kulokhu, isisombululo se-RTK sinenethiwekhi yeziteshi zereferensi ezitholakalayo, okuvumela umamukeli womsebenzisi ukuthi axhume kunoma yisiphi isiteshi sereferensi ngokulandela isimiso esifanayo. Uma usebenzisa inethiwekhi yeziteshi zereferensi, ukumbozwa kwesixazululo se-RTK kuzokwenyuka kakhulu.

Ngenethiwekhi yeziteshi eziyisethenjwa, kungenzeka ukwenza imodeli yamaphutha ancike ebangeni ngokunembe kakhudlwana. Ngokusekelwe kule modeli, ukuncika ebangeni le-antenna eseduze kuncishiswe kakhulu. Kulokhu kusetha, isevisi idala i-Virtual Reference Station (VRS) ecatshangelwayo eduze nomsebenzisi, empeleni imodela amaphutha endaweni yomamukeli womsebenzisi. Ngokuvamile, le ndlela inikeza izilungiso ezingcono kuyo yonke indawo yesevisi futhi ivumela inethiwekhi yesiteshi sereferensi ukuthi ingabi minyene kakhulu. Iphinde inikeze ukwethembeka okungcono ngoba incike kancane esiteshini esisodwa sereferensi.

Ngamafuphi, ngokusebenzisa amasu okulinganisa ukulungisa amaphutha ezinhlelweni zokuzulazula zesathelayithi, i-RTK ivula amathuba okuba ubuchwepheshe be-GNSS bufinyelele ukunemba kwezinga lesentimitha. Ukunemba okuhle kakhulu kwe-RTK kuyenza ibe inketho ekahle kumaphrojekthi amaningi ezimboni, okuhlanganisa ezolimo, izimayini nokuthuthukiswa kwengqalasizinda. Kulezi zimboni, ukuma okunembile kubalulekile ukuze uphumelele. Ukuthatha ezolimo njengesibonelo, ngokuqinisekisa ukuqaliswa okunembile kwemisebenzi yezolimo, abalimi bangathuthukisa ukusebenza kahle kokusebenza. Lokhu akugcini nje ngokukhulisa isivuno sezitshalo, kodwa futhi kuthuthukisa ukusetshenziswa kwezinsiza ezifana nomanyolo namanzi, ngaleyo ndlela konga izindleko futhi kwakhiwe izindlela zokulima ezizinzile.

I-3Rtablet manje isekela imojula eyakhelwe ngaphakathi ye-RTK yokuzikhethela kuthebhulethi yakamuva ye-AT-10A, ethuthukisa nakakhulu ukusebenza kwethebhulethi ezimeni ezihlukene zohlelo lokusebenza nezimo zokusebenza ezinzima. Ngokufinyelela idatha yokuma enembe kakhulu kumadivayisi aphathwayo, ochwepheshe abavela kuyo yonke imikhakha yempilo bangenza umsebenzi wasensimini kalula nangokunembile.
