问题
I'm currently using the Dronekit-python API with MAVProxy to log attitude from a Pixhawk on an onboard computer running Linux. These measurements need to be integrated with external data for image processing, and I'm hoping to use a GPS timestamp for synchronization.
The time of interest is time_utc in MAVLink message #63 (GLOBAL_POSITION_INT_COV), as documented here, and I was unable to find any GPS timestamp parameter listed in the DroneKit-Python API Reference.
I'd appreciate any suggestions on retrieving the timestamp.
