As a full-constellation GNSS module, UM982 tracks GPS, BDS, GLONASS, Galileo and QZSS for stable satellite signals. Embedded anti-jamming technology and enhanced RTK engine solution significantly improve RTK accuracy and reliability in complex environments such as urban blocks and tree shade.
Measuring only 16mm x 21mm x 2.6mm and with a 48-pin surface mount design, the UM982 can be easily embedded into most devices. With 600mW low power consumption, UM982 is more suitable for applications that are highly sensitive to power consumption such as UAVs.
