U-BLOX F10 dual-band GNSS (Global Navigation Satellite Systems) platform combines L1 and L5 bands to provide enhanced multipath resistance and meter-level positioning accuracy. The platform caters to urban mobility applications, such as aftermarket telematics and micromobility. Combined with the well-established L1 band, an L1/L5 dual-band GNSS receiver can deliver < 2 m positioning accuracy (CEP50), against about 4 m with the L1 band only. The u-blox team has conducted driving tests in several urban areas, confirming a significant improvement over GNSS L1 receivers. F10’s firmware algorithm prioritizes L5 band signals in weak signal environments, ensuring reliable positioning accuracy even when paired with small antennas. The platform is also equipped with protection-level technology that provides a real-time trustworthy positioning accuracy estimate.
