Select input coordinate frame — Input coordinate frame

NED (default) | Fixed-frame | ICRF

Select the input coordinate frame to position aerospace vehicles with respect to north-east-down (NED), fixed-frame (Fixed-frame), or International Celestial Reference Frame (ICRF).

If the model contains an associated Simulation 3D Scene Configuration block, Simulation 3D Light Helicopter Pack block uses the coordinate frame of the Simulation 3D Scene Configuration. In this case, the Select input coordinate frame might be disabled. For more information about the Simulation 3D Light Helicopter Pack block coordinate frame, see Algorithms.

Programmatic Use

To set the block parameter value programmatically, use the set_param function.

To get the block parameter value programmatically, use the get_param function.

Parameter:	GeoRadioButton
Values:	'NED' (default) | 'Fixed-frame' | 'ICRF'

Algorithms

If a model contains a Simulation 3D Light Helicopter Pack block and an associated Simulation 3D Scene Configuration block, the Input tab options of Simulation 3D Light Helicopter Pack block might be disabled. In this case, the Simulation 3D Light Helicopter Pack block synchronizes its coordinate system with the scene specified for the Simulation 3D Scene Configuration block if the scene appears in this table.

Simulation 3D Scene Configuration Block Scene	Simulation 3D Light Helicopter Pack Coordinate System
Airport	NED
Earth, Moon, and Space	ICRF
Geospatial with LLA origin	NED
Geospatial with tileset center origin	Fixed-frame

For more information on ICRF and fixed-frame coordinate systems, see ECI and ECEF Coordinates.

The Simulation 3D Light Helicopter Pack block does not synchronize with any other scene selections in the Simulation 3D Scene Configuration block.

Version History

Introduced in R2023b

R2025a: Simulation 3D Light Helicopter Pack block now synchronizes coordinate frame with Simulation 3D Scene Configuration block

The Simulation 3D Light Helicopter Pack block has these changes:

• The Geospatial tab was renamed to Input tab.

• On the Input tab, the Select input coordinate frame pane now contains these coordinate frame buttons:

  • Fixed-frame — Fixed-frame coordinate frame. When you select this coordinate frame, the annotation Fixed-frame appears under the pack block icons.

  • ICRF — International Celestial Reference Frame coordinate frame. When you select this coordinate frame, the annotation ICRF appears under the pack block icons.

  • NED — North-east-down coordinate frame. When you select this coordinate frame, the annotation NED appears under the pack block icons.

  If a model contains a Simulation 3D pack block and an associated Simulation 3D Scene Configuration block, the Input tab options of Simulation 3D Light Helicopter Pack might be disabled. In this case, the Simulation 3D Light Helicopter Pack synchronizes coordinate systems with the Simulation 3D Scene Configuration block.

• The coordinate system displays as an annotation under the block.

• The Enable geospatial correction and Direction of x-axis (degrees clockwise from north) parameters have been removed.

R2024a: Simulation 3D Light Helicopter Pack Block Now Supports Earth-centered Earth-fixed (ECEF) Input Coordinate Frame

To enable ECEF coordinate systems for translation input, the Simulation 3D Light Helicopter Pack block has been updated. Use these parameters with the Use Earth center as origin (ECEF) parameter in the Simulation 3D Scene Configuration block.

• Select input coordinate frame

  • ECEF — ECEF input coordinate frame. When you select this coordinate frame, the annotation Origin: Earth center (ECEF) appears under the pack block icons.

  • NED — NED coordinate frame. Prior to R2024a, NED was the only supported coordinate frame.

• Direction of x-axis (degrees clockwise from north) — Direction of the x-axis. This parameter is enabled when you select the Enable geospatial correction check box.
