Description:
Based on the AG3335 chip by 12nm technology, GE-M121 is able to simultaneously track signals from all civil navigation systems, i.e. GPS, GLONASS, GALILEO, BEIDOU, QZSS, and SBAS. Thanks to this capability, positioning becomes easy even in the typical GPS difficult environments. To simplify the RF design, GE-M121 allows direct connection of passive patch antenna without additional gains added.Specifications
