Copyright 2026 CogniPilot Foundation

This product includes software developed by the CogniPilot Foundation.
This repository is licensed under the Apache License, Version 2.0; see the
root LICENSE file. Every Modelica source here is original CogniPilot content
under that license.

CogniPilot repositories carry no third-party-derived source. Ekf2/, a
statement-for-statement transcription of PX4-Autopilot's ekf2 module and
therefore BSD-3-Clause rather than Apache-2.0, was relocated out of this
repository for that reason. It is maintained separately as a PX4-parity
oracle, consumed only as an external comparator whose outputs are compared,
never as in-tree source. It was not referenced by any package here and was
not part of the released library archive.

This NOTICE records the remaining third-party content redistributed in this
repository and the license each is under. It is the top-level index; the
authoritative text for each entry is the license file named in that entry.


1. Geodesy/WMM2025/ -- US Government public domain, NOAA/NCEI and BGS
---------------------------------------------------------------------

Geodesy/WMM2025 is a pure-Modelica port of the World Magnetic Model 2025
degree/order-12 spherical-harmonic evaluation and carries the WMM2025
coefficient set.

    Source:    World Magnetic Model 2025 (WMM2025)
    Producers: NOAA National Centers for Environmental Information (NCEI),
               United States, jointly with the British Geological Survey
               (BGS), United Kingdom
    Status:    The WMM software and coefficients are in the public domain in
               the United States. BGS is a joint producer of the model and is
               credited here; NOAA and BGS do not endorse this port.

2. Modelica derived from CogniPilot Python implementations -- Apache-2.0
------------------------------------------------------------------------

Three packages state in-tree that they follow an implementation in another
CogniPilot repository. All three upstreams are Apache-2.0, the same license
this repository is under, so no additional condition attaches; they are listed
so a reader need not go looking.

    Vehicles/Templates/FixedWingPlant.mo
        follows CogniPilot/cubs2, cubs2_dynamics/cubs2_dynamics/sportcub.py
        Apache-2.0, Copyright CogniPilot Foundation
    Control/Multirotor/LogLinear/
        follows CogniPilot/cyecca, cyecca/models/rdd2_loglinear.py
        Apache-2.0, Copyright CogniPilot Foundation
    Planning/Bezier/
        follows CogniPilot/cyecca, cyecca/models/bezier.py
        Apache-2.0, Copyright CogniPilot Foundation


3. Tooling invoked but not redistributed
----------------------------------------

flake.nix pins OpenModelica (OSMC-PL / GPL-3.0) and git (GPL-2.0) as
development-shell and container tools. They are invoked as separate
executables, are never linked into or redistributed with anything this
repository produces, and are not in the closure of packages.default. No
copyleft term attaches to this repository's output.
