Dual Frequency Multi-system RTK Positioning Module
ER-GNSS-M08 is a new generation of BDS/GPS/GLONASS/Galileo/ QZSS dual-frequency multi-system centimeter-level RTK positioning module. Based on a new generation of RF base band and high-precision algorithm integrated GNSS SoC chip, built-in high-performance CPU, and integrated double-precision floating-point processor and RTK special coprocessor, using advanced low-power technology, can achieve 10Hz RTK positioning results output.
The ER-GNSS-M08 module supports full-system dual-frequency positioning or single-system independent positioning, which is suitable for high-precision navigation and positioning fields such as intelligent logistics, intelligent security, intelligent home, intelligent machinery, etc.
