The GoPro Hero 7 has a build in GPS.
You can extract the track with some tools: https://tailorandwayne.com/gpmd2csv/
You get a GPX file per video file. I used GPSAR to merge them together.
Uploading to GPS-Speedsurfing fails.
Took some time to figure out the problem: I think it has too many track points.If I open the GPX file I get 20 track points per second!! I think that GPS-Speedsurfing cannot handle this, the time differences between the track-points are too small.
I used GarmingBaseCamp to filter the GPX file to 2 second interval, just to test it. (1 sec interval is possible)
The GPX file even contains the GpsAccuracy (dont known what the number means) I see numbers between 130 and 300.
I don't think the GoPro Hero 7 is a serious GPS for records, but it might be an option for the recrational surfer. I was still using a Geko 201, which is propable far less accurate.
I might write some software that calls the gpmd2gpx tool and then merges and filters the GPX file.
