Sidereon.Propagator (Sidereon v0.9.0)

High-precision numerical orbit propagation.

Supports high-order adaptive numerical integration (DP54) of orbital states using various force models via Rust NIF.

Summary

state()

vec3()

Adaptive step propagation using Dormand-Prince 5(4) via Rust NIF. Returns the state at exactly t_end.

@type state() :: {r :: vec3(), v :: vec3()}

@type vec3() :: {float(), float(), float()}

@spec propagate(state(), float(), keyword()) :: {:ok, state()} | {:error, any()}

Adaptive step propagation using Dormand-Prince 5(4) via Rust NIF. Returns the state at exactly t_end.

:tolerance - Integration tolerance (default: 1.0e-12)
:forces - List of active force models: ["twobody", "j2"] (default: ["twobody"])
