The Full System Multi-frequency High-precision Positioning Module
ER-GNSS-M09 is a new generation of BDS/GPS/GLONASS/Galileo/QZSS multi-frequency high-precision GPS-RTK positioning module in the system, based on the star through independent research and development and the core of a new generation of RF GNSS base-band and high-precision algorithm integration – NebulasIV SoC chip design. It can simultaneously track BDS B1I/B2I/B3I/BIC/B2a*, GPS LIC/A/L2P/ L5, GLONASS L1/L2, Galileo E1/E5b/E5a, QZSS L1/L2/L5 and other signal frequency points. For deformation monitoring, high-precision GIS, drones, lawnmowers, precision agriculture, Surveying and mapping and intelligent driving and other high-precision navigation and positioning fields.
