Position Setpoint

Reads position setpoint

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 Position Setpoint block outputs the vehicle's desired position (in meters) with respect to the origin in the NED (North-East-Down) frame, which is a coordinate system used in navigation. This is used to describe the position relative to a reference point, typically the starting location of the vehicle.

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.
