How to combine a virtual gps in Node-RED with a real one

Interesting, our approach is more technical. After cleaning up the NMEA data we first use non-positional data to filter out outliers, this works well under bridges for instance. Then we keep track of speed and use motor power to filter out impossible speed jumps based on maximum acceleration / deceleration foremost. Skipped datapoints are replaced by estimations/extrapolations to keep up with the roughly 1Hz update interval. This then gets fed through a rather fast weighted averaging filter of …

Not mentioned there but visible in the Node-RED flow is how we override the RPM value (virtual motor) with a ‘consumption’ value in Ah/km.
