New LLA to Flat Earth Block
The LLA to Flat Earth block estimates the flat Earth position from geodetic latitude,
longitude, and altitude.
New International Geomagnetic Reference Field 11 Block
The International Geomagnetic Reference Field 11 block calculates the Earth's
magnetic field and secular variation using the eleventh generation of the International
Geomagnetic Reference Field.
Spherical Harmonic Gravity Model Supports New Planet Model
The Spherical Harmonic Gravity Model block now supports the EIGEN-GL04C gravity
field model.
Simulink Coder Inlined Code Generation
The following blocks now generate inlined code for all targets:
• COESA Atmosphere Model
• Pressure Altitude
• Non-Standard Day 210C
• Non-Standard Day 310
• NRLMSISE-00 Atmosphere Model
• WGS84 Gravity Model
• Spherical Harmonic Gravity Model
In previous releases, if your model contained these blocks, you needed to perform the
following to generate code:
• In the Simulink Configurations Parameters pane, select the Support: non-inlined
S-functions check box on the Code Generation > Interface pane.
• Include other source files to generate code.
Compatibility Considerations
You can now generate code directly from models that contain these blocks. To use
existing models:
