About
The M-GNSSB-RX is a compact multiband GNSS OEM receiver board developed by Arralis for high-precision positioning and navigation applications. It simultaneously receives GPS L1 and BeiDou B1 signals in the 1560-1610 MHz band and supports Real-Time Kinematic (RTK) correction technology for centimeter-level positioning accuracy in demanding environments.
The board operates from a 3.3-5 V supply drawing just 25 mA, making it highly power-efficient for battery-operated and space-constrained systems. Data interfaces include UART (compatible with 3.3 V logic) and RS-485 (requiring 5 V), providing flexibility for integration with embedded processors, mission computers, and secure communication systems.
The M-GNSSB-RX is designed for applications including defense navigation systems, autonomous vehicle positioning, urban canyon navigation, port logistics, and railway positioning where multi-constellation GNSS with RTK augmentation is required for resilience and accuracy. The OEM board form factor enables OEM integration into custom navigation units and satellite payloads.
