Cov Lus Qhia Txog
Daim ntawv thov khwv:
Qhov tseeb ntawm lub sij hawm kinematic (RTK) yog tus txheej txheem satellite navigation uas siv los txhim kho qhov tseeb ntawm cov ntaub ntawv muab los ntawm satellite-positioning systems (thoob ntiaj teb navigation satellite systems, GNSS) xws li GPS, GLONASS, Galileo, thiab BeiDou. Nws siv cov kev ntsuas ntawm theem ntawm lub teeb meem lub cab kuj yoj ntxiv rau cov ntsiab lus ntawm lub teeb liab thiab kev tso siab rau ib qho chaw siv los yog interpolated virtual chaw nres tsheb los muab cov kev kho tam sim, muab kom txog li ntawm centimeter. Nrog siv GPS rau hauv particular, qhov system feem ntau hu ua cov cab kuj-theem, lossis CPGPS. Nws muaj cov kev siv hauv daim ntawv ntsuam xyuas thaj av, kev tshawb fawb txog dej, thiab hauv kev tsav tsheb tsis tau tsav tsheb.
Siv:
GPS RTK GNSS muaj lub chaw nres tsheb hauv paus, uas saib cov teeb liab los ntawm cov xev, ib lossis ntau tus neeg siv rover uas lub chaw nres tsheb los xa xov xwm, thiab ib txoj kev sib txuas lus nrog lub hauv paus broadcasts kho cov ntaub ntawv rau cov neeg siv nyob rau ntawm lub sijhawm. RTK GNSS muab cov lus qhia zoo heev hauv thaj tsam ntawm qhov chaw nres tsheb hauv no.
