When running DriverWorks/RoadRunner, we are accessing the localization result data which includes GPS coordinates on where the vehicle is located within the HD MAP/segment according to this:

https://docs.nvidia.com/drive/driveworks-3.5/group__localization__group.html

When passing under a bridge/gantry, there is a momentary GPS signal lost causing the localization GPS fields to be zeros (GPS point goes to the Ocean).

Does anybody experience this behavior and advise why the localization GPS fields can’t keep providing good positioning by using other sensors IMU, Camera, Radars?

The API and RoadRunner functionalities are not available in this particular version. It’s worth noting that this forum is primarily intended for developers utilizing devzone releases, so it’s unlikely that other developers will have the relevant experience or information regarding these specific features. I just wanted to inform you about this.
