Investigating the need for conversion of location.gnss.speed #30

Open timbellomo opened 3 weeks ago

njord is reporting unrealistic speeds in its TAIP message, such as an engine traveling 108 MPH on the highway. While possible, it's much more likely that location.gnss.speed reports KPH, and the engine was actually traveling ~67 MPH.

Need to confirm this issue and its fix.

Please provide real world location.gnss.speed samples. Based on the Airlink AOS documentation, I believe this is the uncompensated, instantaneous speed which makes either value equally likely
