Product Introduction
The MM118EL is a dual-frequency (L1+L5) RTK integrated navigation module developed by MXGNSS for the intelligent driving market. Built on proprietary high-precision chip design, it supports multi-constellation (BDS, GPS, Galileo，QZSS) combined with dual-frequency RTK technology and advanced integration algorithms. With full use of GNSS, IMU, wheel speed, and dynamic model, the product can provide continuous centimeter-level accuracy, ensuring reliability in occlusion environments such as overpasses, tunnels, and underground garages. The product stands out for its robust anti-jamming capabilities, low power consumption with good cost performance, widely used in global positioning application markets such as lawnmowers and vehicles.
