Indawo yeKinematic yeXesha langempela (RTK): Umncedisi onamandla wokuphucula ukuchaneka komsebenzi wemizi-mveliso

Ukubeka i-kinematic positioning ngexesha langempela (RTK) yindlela elungisa iimpazamo eziqhelekileyo kwiinkqubo ze-satellite navigation (GNSS) zangoku. Ukongeza kumxholo wolwazi lwesignali, ikwasebenzisa ixabiso elilinganisiweyo lesigaba sokuthwala isignali, kwaye ixhomekeke kwisikhululo esinye sereferensi okanye isikhululo esibonakalayo se-interpolation ukubonelela ngolungiso lwexesha langempela, ibonelela ngokuchaneka ukuya kwinqanaba leesentimitha.

IngatshatangaSi-RTK yesitishi

Indlela elula yokulinganisa i-RTK yenziwa ngoncedo lwee-RTK receivers ezimbini, ezibizwa ngokuba yi-RTK yesitishi esinye. Kwi-RTK yesitishi esinye, i-reference receiver imiselwa phezu kwendawo enesikhundla esaziwayo kwaye i-rover (i-moving receiver) ibekwa phezu kwamanqaku apho indawo yayo iza kugqitywa. Ngokusebenzisa indawo ehambelanayo, i-rover idibanisa ukubonwa kwayo kwe-GNSS kunye nesitishi sereferensi ukunciphisa imithombo yempazamo ize emva koko ifumane indawo. Oku kufuna ukuba isitishi sereferensi kunye ne-rover zibone iqela elifanayo lee-satellite ze-GNSS ngaxeshanye, kwaye ikhonkco ledatha linokudlulisa indawo kunye neziphumo zokujonga zesitishi sereferensi kwisitishi se-rover ngexesha langempela.

I-RTK yeNethiwekhi (i-NRTK)

Kule meko, isisombululo se-RTK sinothungelwano lwezikhululo zesalathiso esisetyenziswayo, nto leyo evumela umsebenzisi ukuba aqhagamshelane nasiphi na isikhululo sesalathiso ngokulandela umgaqo ofanayo. Xa usebenzisa inethiwekhi yezikhululo zesalathiso, ukugubungela isisombululo se-RTK kuya kwanda kakhulu.

Ngenethiwekhi yezikhululo zesalathiso, kunokwenzeka ukwenza iimodeli zeempazamo ezixhomekeke kumgama ngokuchanekileyo. Ngokusekelwe kule modeli, ukuxhomekeka kumgama oya kwi-antenna ekufutshane kuncitshisiwe kakhulu. Kule setingi, inkonzo idala iSikhululo seReferensi esibonakalayo (i-VRS) esikufutshane nomsebenzisi, nto leyo eyenza iimodeli zeempazamo kwindawo yomamkeli womsebenzisi. Ngokubanzi, le ndlela ibonelela ngolungiso olungcono kuyo yonke indawo yenkonzo kwaye ivumela inethiwekhi yesikhululo sesalathiso ukuba ingaxinani. Ikwabonelela ngokuthembeka okungcono kuba ayixhomekekanga kakhulu kwisikhululo sesalathiso esinye.

Ngamafutshane, ngokusebenzisa iindlela zokulinganisa ukulungisa iimpazamo kwiinkqubo zokuhamba ngesathelayithi, i-RTK ivula ithuba lokuba iteknoloji ye-GNSS ifikelele ekuchanekeni kwinqanaba leesentimitha. Ukuchaneka okugqwesileyo kwe-RTK kwenza ukuba ibe lukhetho olufanelekileyo kwiiprojekthi ezininzi zoshishino, kuquka ezolimo, ezemigodi kunye nophuhliso lweziseko. Kule mizi-mveliso, ukubeka indawo ngokuchanekileyo kubalulekile kwimpumelelo. Ukuthatha ezolimo njengomzekelo, ngokuqinisekisa ukuphunyezwa ngokuchanekileyo kwemisebenzi yezolimo, abalimi banokuphucula ukusebenza kakuhle. Oku akugcini nje ngokwandisa isivuno sezityalo, kodwa kukwaphucula ukusetyenziswa kwezixhobo ezifana nezichumisi namanzi, ngaloo ndlela konga iindleko kwaye kudale iindlela zokulima ezizinzileyo.

I-3Rtablet ngoku ixhasa imodyuli ye-RTK eyakhelwe ngaphakathi kwithebhulethi yamva nje ye-AT-10A, ephucula ngakumbi ukusebenza kwethebhulethi kwiimeko ezahlukeneyo zokusetyenziswa kunye neemeko zokusebenza ezinzima. Ngokufikelela kwidatha yokubeka echanekileyo kakhulu kwizixhobo eziphathwayo, iingcali ezivela kuzo zonke iinkalo zobomi zinokwenza umsebenzi wasentsimini ngokulula nangokuchanekileyo.
