Embedded GNSS IC enhances IoT positioning accuracy


u-blox has introduced F10, the corporate’s first dual-band GNSS (International Navigation Satellite tv for pc Techniques) platform combining L1 and L5 bands to supply enhanced multipath resistance and meter-level positioning accuracy. The platform caters to city mobility purposes, corresponding to aftermarket telematics and micromobility.

Functions that use GNSS receivers for correct positioning are on the rise. But, present receivers don’t absolutely carry out in city areas. Correct and dependable positioning in dense city environments, the place buildings or tree foliage can replicate satellite tv for pc indicators, requires GNSS receivers to mitigate multipath results. The L5 band’s resilience to those results considerably improves positioning accuracy. Mixed with the well-established L1 band, an L1/L5 dual-band GNSS receiver can ship < 2 m positioning accuracy (CEP50), in opposition to about 4 m with the L1 band solely. The u-blox workforce has performed driving checks in a number of city areas, confirming a major enchancment over GNSS L1 receivers.

The F10’s firmware algorithm prioritizes L5 band indicators in weak sign environments, making certain dependable positioning accuracy even when paired with small antennas. The platform can be outfitted with protection-level expertise that gives a real-time reliable positioning accuracy estimate.

When a mobile modem is extraordinarily near a GNSS receiver, it will possibly intrude with the receiver’s reception. Some F10 module fashions (NEO-F10N, MAX-F10S, and MIA-F10Q) are outfitted with a strong RF circuit that permits the GNSS and the mobile modem to function with out interference.

The u-blox F10 platform is pin-to-pin appropriate with the earlier u-blox M10 technology for straightforward migration. It additionally helps u-blox AssistNow, which presents real-time on-line A-GNSS service with world availability to cut back GNSS time-to-first-fix and energy consumption.

The u-blox EVK-F101 analysis equipment will likely be out there in April 2024.
