3 @page gps_usecase3 Timestamp options
5 @note SW Release Applicability: This tutorial is applicable to modules in both **NVIDIA DriveWorks** and **NVIDIA DRIVE Software** releases.
7 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`.
9 Note: this parameter does not modify raw data. For more information, see @ref sensors_usecase4.
