GNSS tino tika

BDS/GPS/GLONASS/Galileo/QZSS

Pūnaha whānui, auau-katoa, tino tika te tūnga me te aronga

Ko te UM982 he whakatupuranga hou o te pūnaha BDS, GPS, GLONASS, Galileo, QZSS, SBAS, he waeine tūnga me te aronga tino tika, he auau-katoa, he tino tika, i whakawhanakehia motuhaketia e Hexinxingtong. E hangai ana ki te whakaurunga o tētahi whakatupuranga hou o te auau reo irirangi me ngā rauropi tino tika i whakawhanakehia motuhaketia e Hexinxingtong. He maramara GNSS SoC—he hoahoa NebulasIV. Ka taea e te UM982 te whai i ngā tohu BDS B11, B21, B31, GPS L1, L2, L5, GLONASSSG1, G2, GalileoE1, E5a, E5b, QZSSL1, L2, L5 me ētahi atu tohu maha-auau, ā, e tautoko ana i ngā momo tūnga hononga maha-pūnaha me ngā momo tūnga motuhake kotahi-pūnaha. , ka taea e ngā kaiwhakamahi te whirihora ngāwari. He waeine ārai-whakararuraru matatau kua hangaia ki roto i te UM982, ka taea te whakarite i te tika o te tūnga pono me te tika ahakoa i roto i ngā taiao hikohiko uaua. Ko te nuinga o te wā e aro ana ki ngā mara pēnei i ngā waka rererangi kore-taro, ngā mīhini tapahi tarutaru, te ahuwhenua tino tika, me ngā whakamātautau taraiwa atamai, e tautoko ana i te tūnga RTK i runga i te maramara auau-katoa, pūnaha-katoa me te tatau ahunga pūihi-rua, ā, ka taea te whakamahi hei teihana pūkoro, hei teihana turanga rānei.
