The GPS sensor provides several timestamp options depending on sensor type. These options can be toggled using the output-timestamp sensor parameter, and work by modifying the dwGPSFrame.timestamp_us returned when reading a frame. The following table summarizes the timestamp options available for each supported GPS sensor. The default option is host.
Note: this parameter does not modify raw data. For more information, see Sensor Timestamping.
