Note: SW Release Applicability: This tutorial is applicable to modules in both NVIDIA DriveWorks and NVIDIA DRIVE Software releases.

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.
