Package
MS34SNA with IMU is a high dynamic, supporting simultaneous multi-constellation positioning and L1+L5, GNSS module with integrated RTK positioning engine. Built-in 12nm advanced process GNSS Soc chip, integrated dual-core Cortex A7 1.2GHz high-performance computing processor, the module supports GPS, BDS, GLONASS, GALILEO and QZSS multi-satellite systems, and integrates 6-axis sensors (3-axis gyroscope) + 3-axis accelerometer) and GNSS RTK tightly combined algorithm engine, MS34SNA can achieve centimeter-level positioning accuracy, greatly improve the positioning accuracy of the device, and support a maximum 20Hz fusion positioning refresh rate.
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.
