    Making the invisible visible

    Every trip logs thousands of silent data points. Here’s what happens when you put them on a map.

    Field Captures

    Signal, speed, and terrain — layered

    A selection of logged runs from our test fleet, rendered as heatmaps and overlays, alongside the hardware that made them.

    From Raw to Real

    One log line. One picture.

    Raw CSV Row

    What the device writes

    Timestamp, latitude, longitude, speed in knots, signal bars, RSSI in dBm, and measured bandwidth — one dense row per second, thousands per trip.


    No color, no shape, no story. Just numbers waiting to be plotted.

    Mapped Output

    What you actually see

    The same row becomes a colored point on a live map — red for dropped signal, green for strong bandwidth, sized by speed.


    Export straight into a Google Sheet, ready to layer onto Maps in minutes.

    Why It Matters

    Coverage gaps are invisible until they aren’t

    A dropped call, a stalled upload, a missed alert offshore — every gap has a location and a cause. Our logs turn that frustration into a data point you can act on.
