Real-time kinematic positioning (RTK) ndi njira yomwe imakonza zolakwika zofala pamakina apano a satellite navigation (GNSS). Kuphatikiza pa zomwe zili mu chizindikirocho, imagwiritsanso ntchito mtengo woyezera wa gawo lonyamula ma siginecha, ndipo imadalira malo amodzi ofotokozera kapena ma interpolation virtual station kuti ipereke zowongolera zenizeni, kupereka kulondola mpaka mulingo wa centimita.
WokwatiwaSgawo RTK
Fomu yoyezera kwambiri ya RTK imachitika mothandizidwa ndi olandila awiri a RTK, omwe amatchedwa single station RTK. Mu siteshoni imodzi ya RTK, wolandila amakhazikitsidwa pamwamba pa mfundo yomwe ili ndi malo odziwika ndipo rover (moving receiver) imayikidwa pamwamba pa mfundo zomwe malo ake ayenera kutsimikiziridwa. Pogwiritsa ntchito malo ocheperako, rover imaphatikiza zowonera zake za GNSS ndi malo ofotokozera kuti muchepetse magwero a zolakwika kenako ndikupeza malowo. Izi zimafuna kuti malo owonetserako ndi rover ayang'ane gulu lomwelo la ma satelayiti a GNSS nthawi imodzi, ndipo ulalo wa data ukhoza kufalitsa malo ndi zotsatira zowonera pa siteshoni ya rover mu nthawi yeniyeni.
Network RTK (NRTK)
Pachifukwa ichi, yankho la RTK lili ndi maukonde opangira malo omwe ali nawo, omwe amalola wolandila kuti alumikizane ndi siteshoni iliyonse potsatira mfundo yomweyo. Mukamagwiritsa ntchito netiweki yamalo ochezera, kufalikira kwa yankho la RTK kudzakulitsidwa kwambiri.
Ndi netiweki yamalo ofotokozera, ndizotheka kutengera zolakwika zomwe zimadalira patali molondola. Kutengera chitsanzo ichi, kudalira mtunda wopita ku mlongoti wapafupi kumachepetsedwa kwambiri. Pakukhazikitsa uku, ntchitoyi imapanga malo ongoyerekeza a Virtual Reference Station (VRS) pafupi ndi wogwiritsa ntchito, potengera zolakwika zomwe zili pamalo a wolandila. Nthawi zambiri, njirayi imapereka zowongolera bwino m'dera lonse lautumiki ndipo imalola kuti maukonde a station station akhale ochepa. Zimaperekanso kudalirika kwabwinoko chifukwa zimadalira pang'ono pa malo amodzi.
Mwachidule, pogwiritsa ntchito njira zoyezera kukonza zolakwika pamakina oyendera ma satelayiti, RTK imatsegula mwayi waukadaulo wa GNSS kuti ukwaniritse kulondola kwa centimita. Kulondola kwabwino kwa RTK kumapangitsa kukhala chisankho choyenera pama projekiti ambiri azamakampani, kuphatikiza ulimi, migodi ndi chitukuko cha zomangamanga. M'mafakitalewa, kuyika bwino ndikofunikira kuti zinthu ziziyenda bwino. Kutengera ulimi monga chitsanzo, powonetsetsa kuti ntchito zaulimi zikukwaniritsidwa molondola, alimi atha kuwongolera magwiridwe antchito. Izi sizimangowonjezera zokolola, komanso zimakulitsa kagwiritsidwe ntchito ka zinthu monga feteleza ndi madzi, potero zimapulumutsa ndalama ndikupanga njira zaulimi zokhazikika.
3Rtablet tsopano imathandizira gawo la RTK lomwe mwasankha mu piritsi la AT-10A laposachedwa, lomwe limathandiziranso magwiridwe antchito a piritsi pamachitidwe osiyanasiyana ogwiritsira ntchito komanso zovuta zogwirira ntchito. Pokhala ndi chidziwitso cholondola kwambiri pazida zonyamulika, akatswiri amitundu yonse amatha kugwira ntchito zakumunda mosavuta komanso molondola.
