I-Real-time Kinematic Positioning (RTK): uMncedisi onamandla wokuphucula ukuchaneka komsebenzi woShishino

I-Real-time kinematic positioning (RTK) bubuchule obulungisa iimpazamo eziqhelekileyo kwiinkqubo zangoku ze-satellite navigation (GNSS). Ukongeza kumxholo wolwazi wesignali, iphinda isebenzise ixabiso elilinganisiweyo lesigaba somthwali wesignali, kwaye ixhomekeke kwisikhululo esisodwa sokubhekisela okanye i-interpolation isikhululo se-virtual ukubonelela izilungiso zexesha langempela, ukubonelela ukuchaneka ukuya kwinqanaba leesentimitha.

UngatshatangaSumboniso RTK

Ifomu yokulinganisa i-RTK elula iqhutyelwa ngoncedo lwabamkeli ababini be-RTK, ebizwa ngokuba yi-RTK yesitishi esisodwa. Kwisikhululo esisodwa se-RTK, i-reference receiver imiselwe ngaphaya kwendawo enendawo eyaziwayo kunye ne-rover (i-receiver ehambayo) ibekwe phezu kwamanqaku apho isikhundla siza kumiselwa. Ukusebenzisa i-positioning ehambelanayo, i-rover idibanisa ukuqwalaselwa kwayo kwe-GNSS kunye nesikhululo sokubhekisela ukunciphisa imithombo yephutha kwaye emva koko ifumana indawo. Oku kufuna ukuba isikhululo sereferensi kunye ne-rover ziqwalasele iqela elifanayo le-satellites ye-GNSS ngaxeshanye, kwaye ikhonkco ledatha linokudlulisa isikhundla kunye neziphumo zokuqwalaselwa kwesikhululo sokubhekisela kwisikhululo se-rover ngexesha langempela.

Inethiwekhi ye-RTK (NRTK)

Kule meko, isisombululo se-RTK sinothungelwano lwezikhululo zokubhekisela kwindawo yalo, evumela ukuba umamkeli womsebenzisi adibanise nasiphi na isikhululo sokubhekisela ngokulandela umgaqo ofanayo. Xa usebenzisa inethiwekhi yezikhululo zereferensi, ukugubungela isisombululo se-RTK kuya kwandiswa kakhulu.

Ngothungelwano lwezikhululo zereferensi, kunokwenzeka ukwenza imodeli yeempazamo ezixhomekeke kumgama ngokuchanekileyo ngakumbi. Ngokusekwe kule modeli, ukuxhomekeka kumgama kwi-eriyali ekufutshane kuncitshiswe kakhulu. Kolu cwangciso, inkonzo idala iSikhululo seNgcaciso yeNgcaciso yeNgcaciso (VRS) ecingelwayo kufutshane nomsebenzisi, iyenza imodeli yeempazamo kwindawo yomamkeli womsebenzisi. Ngokuqhelekileyo, le ndlela ibonelela ngezilungiso ezingcono kwindawo yonke yenkonzo kwaye ivumela inethiwekhi yesitishi sereferensi ukuba ibe ngaphantsi. Ikwabonelela ngokuthembeka okungcono kuba ixhomekeke ngaphantsi kwisikhululo esinye sokubhekisela.

Ngamafutshane, ngokusebenzisa iindlela zokulinganisa ukulungisa iimpazamo kwiinkqubo zokuhamba ngesathelayithi, i-RTK ivula ithuba letekhnoloji ye-GNSS ukufezekisa ukuchaneka kwenqanaba lesentimitha. Ukuchaneka okugqwesileyo kwe-RTK kuyenza ibe lolona khetho lufanelekileyo kwiiprojekthi ezininzi zemizi-mveliso, kubandakanya ezolimo, imigodi kunye nophuhliso lweziseko ezingundoqo. Kwezi mizi-mveliso, ukubeka kwindawo echanekileyo kubalulekile kwimpumelelo. Ukuthatha ezolimo njengomzekelo, ngokuqinisekisa ukuphunyezwa ngokuchanekileyo kwemisebenzi yezolimo, amafama anokuphucula ukusebenza kakuhle. Oku akugcini nje ukwandisa izivuno zezityalo, kodwa kwandisa ukusetyenziswa kwemithombo yobutyebi efana nezichumisi namanzi, ngaloo ndlela kongiwa iindleko kunye nokwenza iindlela zokulima ezizinzileyo.

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