DVL - Georeferencing video or exporting a timelog of lat long

Hi @GavXYZ,

I believe I responded to this when you asked a few weeks ago in a different post:

The vehicle has internal DataFlash .bin log files, and QGroundControl also logs the MAVLink messages it receives during operation in .log telemetry logs, which can both be parsed using Log Viewer or programs like Pymavlink’s mavlogdump.py.

If you’re using .bin logs the VIS* messages give you the information ArduSub is receiving from the DVL extension, and the POS messages log the vehicle’s position estimate from ArduSub’s sensor fusion (its EKF). In .log files you can look at the GLOBAL_POSITION_INT message data, and possibly also any VISION_* messages that get passed along.

Feel free to follow up if you have additional questions
