    NMEA2000 - Vessel Speed Component Unit

    I have a NMEA 2000 network with an Airmar DX900+ sensor. The sensor provides the 130578 Vessel Speed Components sentence. When I activate the Vessel Speed Components sentence in PGNs receivable by Exp, the BSP value in Expedition shows roughly 50% of expected BSP. Looking in Actisense NMEA Reader, it seems that Expedition shows the Meter per second rather than Knots. My Speed Unit is set to Knots in Expedition. If I change the Speed Unit to Meter per second in Expedition, the BSP value is even additional 50% lower. It seems that Expedition reads the Meter per second value coming out of the NMEA2000 Vessel Speed Component but shows it as Knots
    .
    In PGNs receivable by Exp I have activated both 128259 & 130578.
    I want the Vessel Speed Component for Leeway calculation, not necessary for BSP.

    Is this a bug or a feature

    I have Expedition version 11.0.11
    I have an Actisense NGT-1
    I run all on Windows 10 Pro 1909

    Re: NMEA2000 - Vessel Speed Component Unit

    Thank you, that appears to be a bug.

    Have fixed for the next update.
