Fibocom MGB390-AR is a dual-band multi-GNSS positioning module that supports BDS B1I/B1C/B2A/B2B, GPS L1/L5, GLONASS G1, and Galileo E1/E5. With 180 tracking channels and an update rate of 1-20Hz, the module delivers RTK centimeter-level positioning accuracy (GNSS 1cm + 1ppm), achieving a hot start TTFF of 1s and a cold start of 24s, with cold start sensitivity of -148 dBm and tracking sensitivity of -164 dBm. The module adopts a compact 24 PIN LCC form factor of 12.2 x 16.0 x 2.25 mm and supports Flash programming. It features built-in LNA & SAW, a TCXO oscillator, and integrated antenna open-circuit detection and short-circuit protection, supporting both active and passive antennas. With UART and I2C interfaces, MGB390-AR is well suited for high-precision applications such as surveying and mapping, drones, precision agriculture, and autonomous navigation.
