Support Simultaneous Multi-constellation Positioning MTK Platform High-sensitivity All-constellation GNSS Module
MS34SNA is supporting 'simultaneous multi-constellation positioning'and L1+L5, built-in 12nm advanced process GNSS Soc chip, integrated with main frequency up to 530MHz ARM Cortex-M4 FPU and MPU, and configured with independent dual-core Cortex A7 1.2GHz high-performance computing processor, the module supports GPS, BDS, GLONASS, GALILEO and QZSS multi-satellite systems. Combined with RTK (carrier phase difference) technology, the MS34SNA can achieve centimeter-level positioning accuracy, which greatly improves the positioning accuracy of the device and supports up to 10Hz RTK.
The module makes it ideal for industrial-type applications in the automotive sector (e.g. T-Box, car navigation, V2X), transportation sector (e.g. industrial vehicles, operational vehicle supervision), shared electric bikes, smart agriculture, etc.
