Kuyika Kinematic Positioning mu Real-Time (RTK): Wothandizira Wamphamvu Wokonza Kulondola kwa Ntchito Zamakampani

Kuyika kinematic nthawi yeniyeni (RTK) ndi njira yomwe imakonza zolakwika zomwe zimachitika kawirikawiri mu makina oyendera ma satellite (GNSS) omwe alipo. Kuwonjezera pa zomwe zili mu chizindikirocho, imagwiritsanso ntchito mtengo woyezedwa wa gawo lonyamula ma signal, ndipo imadalira siteshoni imodzi yowunikira kapena siteshoni yolumikizira kuti ipereke kusintha kwa nthawi yeniyeni, kupereka kulondola mpaka mulingo wa sentimita imodzi.

WosakwatiwaStation RTK

Fomu yosavuta kwambiri yoyezera RTK imachitika pogwiritsa ntchito ma receiver awiri a RTK, omwe amatchedwa single station RTK. Mu single-station RTK, receiver imayikidwa pamwamba pa mfundo yokhala ndi malo odziwika ndipo rover (wolandila wosuntha) imayikidwa pamwamba pa mfundo zomwe malo ake ayenera kudziwika. Pogwiritsa ntchito relative positioning, rover imaphatikiza ma GNSS observation ake ndi reference station kuti achepetse magwero a cholakwika kenako nkupeza malo ake. Izi zimafuna kuti reference station ndi rover ziziwona gulu lomwelo la ma GNSS satellites nthawi imodzi, ndipo deta yolumikizira imatha kutumiza malo ndi zotsatira za review station ku rover station nthawi yeniyeni.

RTK ya pa intaneti (NRTK)

Pankhaniyi, yankho la RTK lili ndi netiweki ya malo ofotokozera omwe ali ndi mphamvu zake zokha, zomwe zimalola wolandila wogwiritsa ntchito kulumikizana ndi siteshoni iliyonse yofotokozera potsatira mfundo yomweyi. Pogwiritsa ntchito netiweki ya malo ofotokozera, kufalikira kwa yankho la RTK kudzawonjezeka kwambiri.

Ndi netiweki ya malo ofotokozera, n'zotheka kupanga chitsanzo cha zolakwika zomwe zimadalira mtunda molondola. Kutengera chitsanzo ichi, kudalira mtunda kupita ku antenna yapafupi kumachepa kwambiri. Mu dongosololi, ntchitoyi imapanga malo oyerekeza a Virtual Reference Station (VRS) pafupi ndi wogwiritsa ntchito, zomwe zimapangitsa chitsanzo cha zolakwika pamalo a wolandila wogwiritsa ntchito. Kawirikawiri, njira iyi imapereka kusintha kwabwinoko m'dera lonse lautumiki ndipo imalola netiweki ya malo ofotokozera kukhala yochepa. Imaperekanso kudalirika kwabwino chifukwa imadalira pang'ono siteshoni imodzi yofotokozera.

Mwachidule, pogwiritsa ntchito njira zoyezera kuti akonze zolakwika mu makina oyendera ma satellite, RTK imatsegula mwayi woti ukadaulo wa GNSS ukwaniritse kulondola kwa masentimita. Kulondola kwabwino kwa RTK kumapangitsa kuti ikhale chisankho chabwino kwambiri pamapulojekiti ambiri amakampani, kuphatikizapo ulimi, migodi ndi chitukuko cha zomangamanga. M'mafakitale awa, malo oyenera ndi ofunikira kuti zinthu ziyende bwino. Mwachitsanzo, potengera ulimi, poonetsetsa kuti ntchito zaulimi zikuyendetsedwa bwino, alimi amatha kukonza magwiridwe antchito. Izi sizimangowonjezera zokolola, komanso zimawonjezera kugwiritsa ntchito zinthu monga feteleza ndi madzi, motero zimasunga ndalama ndikupanga njira zolima zokhazikika.

3Rtablet tsopano imathandizira gawo la RTK lopangidwa mwapadera mu piritsi laposachedwa la AT-10A, lomwe limawongolera magwiridwe antchito a piritsi m'njira zosiyanasiyana zogwiritsira ntchito komanso m'mikhalidwe yovuta yogwirira ntchito. Mwa kupeza deta yolondola kwambiri yoyika zinthu pazida zonyamulika, akatswiri ochokera m'mitundu yonse ya moyo amatha kugwira ntchito m'munda mosavuta komanso molondola.
