Isikhundla Se-Kinematic Sesikhathi Sangempela (RTK): Umsizi Onamandla Wokuthuthukisa Ukunemba Komsebenzi Wezimboni

Ukubeka i-kinematic ngesikhathi sangempela (RTK) kuyindlela elungisa amaphutha avamile ezinhlelweni zamanje zokuzulazula kwesathelayithi (GNSS). Ngaphezu kokuqukethwe kolwazi lwesignali, isebenzisa futhi inani elilinganisiwe lesigaba sokuthwala isignali, futhi ithembele esiteshini esisodwa sokubhekisela noma esiteshini esibonakalayo sokuxhumana ukuze inikeze ukulungiswa kwesikhathi sangempela, inikeze ukunemba kuze kufike ezingeni lesentimitha.

OyedwaSi-RTK yesiteshi

Ifomu lokulinganisa le-RTK elilula kakhulu lenziwa ngosizo lwezamukeli ezimbili ze-RTK, ezibizwa ngokuthi i-RTK yesiteshi esisodwa. Ku-RTK yesiteshi esisodwa, isamukeli sereferensi sisethwa phezu kwephuzu elinendawo eyaziwayo bese kubekwa i-rover (isamukeli esihambayo) phezu kwamaphuzu okuzonqunywa indawo yawo. Ngokusebenzisa indawo ehlobene, i-rover ihlanganisa ukubonwa kwayo kwe-GNSS nesiteshi sereferensi ukuze kuncishiswe imithombo yamaphutha bese ithola indawo. Lokhu kudinga ukuthi isiteshi sereferensi ne-rover zibone iqembu elifanayo lama-satellite e-GNSS ngesikhathi esifanayo, futhi isixhumanisi sedatha singadlulisela indawo nemiphumela yokubuka yesiteshi sereferensi esiteshini se-rover ngesikhathi sangempela.

I-RTK Yenethiwekhi (i-NRTK)

Kulesi simo, ikhambi le-RTK linenethiwekhi yeziteshi zokubhekisela ezitholakala kulo, okuvumela umamukeli womsebenzisi ukuthi axhume kunoma yisiphi isiteshi sokubhekisela ngokulandela isimiso esifanayo. Uma usebenzisa inethiwekhi yeziteshi zokubhekisela, ukumbozwa kwekhambi le-RTK kuzokwanda kakhulu.

Ngenethiwekhi yeziteshi zokubhekisela, kungenzeka ukwenza amamodeli amaphutha ancike ebangeni ngokunembe kakhudlwana. Ngokusekelwe kulolu hlobo, ukuncika ebangeni eliya ku-antenna eseduze kuncishisiwe kakhulu. Kulokhu kusethwa, isevisi idala i-Virtual Reference Station (VRS) engokomfanekiso eduze nomsebenzisi, empeleni ikwenza amamodeli amaphutha endaweni yomamukeli womsebenzisi. Ngokuvamile, le ndlela inikeza ukulungiswa okungcono kuyo yonke indawo yesevisi futhi ivumela inethiwekhi yesiteshi sokubhekisela ukuthi ingaminyana kakhulu. Iphinde inikeze ukuthembeka okungcono ngoba ayinciki kakhulu esiteshini sokubhekisela esisodwa.

Ngamafuphi, ngokusebenzisa amasu okulinganisa ukulungisa amaphutha ezinhlelweni zokuzulazula ngesathelayithi, i-RTK ivula ithuba lokuthi ubuchwepheshe be-GNSS bufinyelele ukunemba kwezinga lamasentimitha. Ukunemba okuhle kwe-RTK kwenza kube ukukhetha okuhle kumaphrojekthi amaningi ezimboni, okuhlanganisa ezolimo, izimayini kanye nokuthuthukiswa kwengqalasizinda. Kulezi zimboni, ukubeka indawo efanele kubalulekile empumelelweni. Uma sithatha ezolimo njengesibonelo, ngokuqinisekisa ukuqaliswa okunembile kwemisebenzi yezolimo, abalimi bangathuthukisa ukusebenza kahle. Lokhu akugcini nje ngokwandisa isivuno sezitshalo, kodwa futhi kuthuthukisa ukusetshenziswa kwezinsizakusebenza ezifana nomanyolo namanzi, ngaleyo ndlela kongiwe izindleko futhi kwakhiwe izindlela zokulima ezisimeme kakhudlwana.

I-3Rtablet manje isekela imodyuli ye-RTK eyakhelwe ngaphakathi engakhethwa kuthebhulethi yakamuva i-AT-10A, ethuthukisa ukusebenza kwethebhulethi ezimweni ezahlukene zohlelo lokusebenza kanye nezimo zokusebenza ezinzima. Ngokufinyelela idatha yokubeka enembile kakhulu kumadivayisi aphathekayo, ochwepheshe abavela kuzo zonke izigaba zokuphila bangenza umsebenzi wasensimini kalula nangokunembile.
