Dual-antenna GNSS/GPS Module Provides Accurate Positioning and Orientation Data
The MS36SN4 is a GNSS module with built-in RTK positioning, supporting multi-constellation positioning on L1 and L5 bands. It employs a 12nm GNSS SoC chip with a powerful 530MHz ARM Cortex-M4 processor, including FPU and MPU functions. Compatible with GPS, BeiDou, GLONASS, Galileo, and QZSS systems, the module utilizes RTK technology for centimeter-level accuracy and low power use. Its dual chips enable precise azimuth and static attitude measurement. With exceptional performance, the MS36SN4 suits applications like drones, lawnmowers, and precision agriculture.
