UM981 ke moloko o mocha oa BDS, GPS, GLONASS, Galileo, QZSS module ea tsamaiso e felletseng, e nang le maqhubu a felletseng a RTK/INS e ntlafalitsoeng ka boikemelo ke Hexinxingtong. E thehiloe molokong o mocha oa baseband ea maqhubu a seea-le-moea le algorithm e nepahetseng haholo e kopantsoeng le GNSS e ntlafalitsoeng ka boikemelo ke Hexinxingtong. SoC chip—moralo oa NebulasIV. E ka latela ka nako e le 'ngoe lintlha tsohle tsa sistimi le maqhubu joalo ka BDS, GPS, GLONASS, Galileo, QZSS, NavIC, SBAS, jj. Processor e kopantsoeng ea ntlha e phaphametseng e potlakileng le co-processor e inehetseng ea RTK ho fihlela sephetho sa sephetho sa ho beha 100 Hz. Ha e kopanya chip ea MEMS e ka har'a sekepe le algorithm ea ho tsamaea e kopantsoeng ea U-Fusion, e rarolla bothata ba ho sitisoa ha liphetho tsa ho beha ka lebaka la tahlehelo ea senotlolo sa lets'oao la sathelaete, 'me e ka fana ka boemo bo phahameng bo tsoelang pele libakeng tse rarahaneng joalo ka mehaho, lithanele, li-viaducts le meriti ea lifate. Liphetho tsa ho beha. Bakeng sa ho tsamaea ka mokhoa o nepahetseng haholo le masimo a ho beha joalo ka ho etsa lipatlisiso, 'mapa, temo e nepahetseng, jj.
