It also supports Beidou, GPS, GLONASS, Galileo, and QZSS satellite signals in L1+L5 bands. It is capable of capturing and tracking any multi-satellite hybrid signal, independent of the RTK ground enhanced base station system. In complex urban environment, it can still achieve stable and higher sub-meter positioning accuracy.
