The portable size, centimeter-accurate receiver provides users with an entry-level network real time kinematic (RTK) rover. Sfaira One is equipped with a GNSS module with 1,408 channels for GPS, BDS, GLONASS, Galileo and QZSS tracking — providing centimeter positioning in harsh environments. It also features advanced RTK and an anti-interference algorithm.
