MS34SN3

High-sensitivity Simultaneous Multi-constellation Positioning MTK Platform all-constellation GNSS Module

MS34SN3 is a GNSS module with integrated RTK positioning engine, supporting “simultaneous multi-constellation positioning” and L1+L5. Built-in 12nm advanced process GNSS Soc chip, integrated main frequency up to 530MHz ARM Cortex-M4 FPU and MPU,the module supports GPS, BeiDou, GLONASS, Galileo and QZSS, and with RTK (carrier phase difference) technology, the MS34SN3 can achieve centimeter-level positioning accuracy. The MS34SN3 can greatly improve the positioning accuracy of the device while maintaining ultra-low power consumption.
