Description

Add-On Required: This feature requires the UAV Toolbox Support Package for ArduPilot Autopilots add-on.

The Current Course block reads the current course of the vehicle in degrees from the ArduPilot Attitude Heading Reference System (AHRS).

Use this block to access the estimated heading of the vehicle for navigation, guidance, and control workflows that depend on vehicle orientation. Typical applications include heading feedback for control loops, logging of estimated vehicle heading, and decision-making logic based on vehicle course.

This block supports both ArduCopter and ArduPlane vehicle types.
