Description

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

The Current Position block outputs the vehicle's current position (in meters) with respect to the origin in the NED (North-East-Down) frame, which is a geographic coordinate system that is often used in navigation.

• North (N): Positive direction points toward the North (geographical north).

• East (E): Positive direction points toward the East (perpendicular to North, in the horizontal plane).

• Down (D): Positive direction points downward, toward the Earth's center (vertical component).

This block supports both ArduCopter and ArduPlane vehicle types.
