Not sure if i understand offset correctly. For my flights i modified the telemetry file to reduce the frequency of attitude and other messages. The dcshot message is sometimes skipped otherwise because there are too many messages or reductions in bandwidth. This helps but is not 100% foolproof. Is this what you mean with offset?  The dcshot ids must be consecutive.

The best method is to use ground control points for an area. Then there's no need to use camera data.

Hello fiends, i am using the DCSHOT to put EXIF on my pictures.

I synchronize the picture and DCSHOT using TOW and picture time but i have some problem.

In the ground i synchronize the camera time using gcs UTC time.

When i finalize the flight i generate a gpx file using DCSHOT info's but every time it come with different offset in the gpx file and pictures time. Sometime it come with 17sec, sometime with 1minute ....

Its very .. very strange.

Any one using this type of synchronization ? or use gps itow to do something after the flight ?

I tried to run HiTL to make some tests without success.
Ever using ir sensores the HiTL not work.

I see the gcs sending "gps and sensos" to AP but the gps and attitude AP messages not change.

I appreciate any idea.
