=======

**JAX-compatible SGP4 satellite propagation.**

sgp4jax is a pure-JAX implementation of the SGP4/SDP4 orbital propagator,
the standard algorithm used to predict satellite positions from
Two-Line Element (TLE) sets. Because the entire propagation path is
written in JAX, you get:

- **JIT compilation** — fast repeated evaluations via ``jax.jit``
- **Automatic vectorization** — propagate thousands of time steps in
  parallel with ``jax.vmap``
- **Automatic differentiation** — compute gradients of position/velocity
  with respect to time (or any input) via ``jax.grad``
