Full-system Full-frequency High-precision Positioning Orientation Module
ER-GNSS-M11 is a new generation of BDS/GPS/GLONASS/Galileo/QZSS all frequency and high precision positioning orientation module in the system, based on independent research and development, along with the core of a new generation of RF base band and high-precision algorithm integration GNSS Soc chip-NebulasIV design. The main antenna and the secondary antenna simultaneously track the whole system's full frequency points, including the Beidou three global signal, to achieve on-chip RTK positioning and dual-antenna directional solution. The built-in advanced anti-interference unit ensures that the module can provide reliable and accurate positioning accuracy even in complex electromagnetic environments. For UAV, lawn mower, precision agriculture and intelligent driving and other high-precision navigation and positioning fields.
