Description

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

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.

Ports

Data Types: single

Parameters

Sample time — Interval at which the block reads values

-1 (default)

The time interval at which the block reads values from the ArduPilot Autopilot.
