Current Velocity

Reads current velocity

Since R2025b

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

Libraries:
UAV Toolbox Support Package for ArduPilot Autopilots / Controller Interface Blocks

Description

The Current Velocity block outputs the vehicle's current velocity (in m/s) in the NED (North-East-Down) frame, which is a geographic coordinate system used in navigation.

North (N): Positive direction points towards the North (geographical north).
East (E): Positive direction points towards the East (perpendicular to North, in the horizontal plane).
Down (D): Positive direction points downward, towards the Earth's center (vertical component).

Limitations

This block is not supported in triggered subsystems.
