Jitter in GPS data

[ New ]

I've got a question about jitter in GPS data from a GoPro camera.

 

I'm seeing the following in data extracted from a GoPro:

 

timestamp,latitude,longitude,speed(mps)

2020-06-01 15:24:51.152840,52.4667021,0.9385427,10.921
2020-06-01 15:24:51.254982,52.4666918,0.9385626,10.61
2020-06-01 15:24:51.357124,52.4667092,0.9385281,10.91
2020-06-01 15:24:51.459266,52.4667021,0.9385427,10.921
2020-06-01 15:24:51.561408,52.4666918,0.9385626,10.61
2020-06-01 15:24:51.663550,52.4667092,0.9385281,10.91
2020-06-01 15:24:51.765692,52.4667021,0.9385427,10.921

 

As you can see the data repeats latitude, longitude and speed within a very short space of time. I'm also seeing the bearing flip 180 degrees between other points because they're out of order. The data was taken from someone driving, so there's no way it's correct as represented, and should be a progression of points in a line, with bearing changing only progressively.

 

Is this a faulty GoPro, or a faulty GPS device within the GoPro, or a bad SD card, or something needing a firmware update? Anyone come across anything like this before?

 

Thanks, Tom

Hi @boldbeach40806

 

 

Please see if resetting the camera will help.  Reset Camera Settings

You may also try a manual software update. https://gopro.com/update/

What are you using to extract the data?
