Description
The Spherical Harmonics Model provides high-fidelity gravity field representation for celestial bodies. It loads normalized spherical harmonic coefficients from standard file formats and computes gravitational acceleration at any position, accounting for the non-uniform mass distribution of planets.
Example Use Cases
- High-Fidelity Gravity: Models gravitational perturbations beyond point-mass or J2 approximations for precise orbit propagation.
- Planetary Modeling: Supports gravity models such as EGM96 or GGM05 for Earth and equivalent models for other bodies.
