The gpx-track was created by the "Record Track" button in the target query box. I saw the target to late to to use the VDR plugin (that records the raw incoming NMEA
data). The track on the screen-dump is using the raw NMEA data though.
@Pavel I have not checked the code but I suppose that "Record Track" drops a few decimals?
Since I saw this zig-zag last time I have certainly encountered several hundreds of AIS targets, so I have a hard time seeing this as a general OpenCPN
Let's try to catch a VDR record
