[1.0.1] - 2025-12-04¶

- Added from_omm_elements to SGPPropagator. Supports direct initialization of propagator from OMM elements without needing to go through TLE lines. This is both more accurate as well as more robust to TLE ID depletion. #102
- Add support for event detection to SGPPropagator
Add AOIEntryEvent and AOIExitEvent as premade event detectors. #104

- {D}NumericalOrbitPropagator and python bindings
{D}NumericalPropagator and python bindings
Event detection system for numerical propagators to find events during propagation #89
- Mean to osculating, osculating to mean orbital element transformations
Update OrbitStateProviders to provide state(s)_koe_mean and state(s)_koe_osc
Implement ECI<>ROE direct transformations
Add ephemeris_age to SGPPropagator
Implement Largrange, cubic Hermite, and quintic Hermite interpolation methods.
Add WalkerConstellationGenerator which enables rapidly generating propagators with walker-geometry configurations. #96

- Make access computation use D-type propagators.
Standardize on
Add support for D-type returns to KeplerianPropagator and SGPPropagator
Standardized trait traits for {S|D}StateProvider, {S|D}CovarianceProvider, {S|D}StatePropagator
DTrajectory and DOrbitTrajectory can now store trajectories of arbitrary length
DTrajectory and DOrbitTrajectory can now store stm and sensitivity matricies alongside state and covariance.
Improved test coverage across modules
Changed how third-body ephemeris sources are defined and loaded. DE source is now a parameter instead of set by function name. Dynamically load BSP files when called.
Changed how Gravity models are defined in terms of enumeration types.
Renamed state_cartesian_to_osculating and state_osculating_to_cartesian as state_eci_to_koe and state_koe_to_eci #89

- Added relative_motion submodule to contain functionality related to relative motion
Implemented RTN rotation and state transformations: rotation_eci_to_rtn, rotation_rtn_to_eci, state_eci_to_rtn, and state_rtn_to_eci
Implemented Relative Orbital Element (ROE) state transformations state_oe_to_roe and state_roe_to_oe
Added util::math functions sqrtm and spd_sqrtm to calculate matrix square root
