Detailed Description

TLE parsing and SGP4 propagator C++ wrappers.

RAII wrappers around the siderust_tle_* and siderust_sgp4_* FFI functions.

Typical usage

#include <siderust/sgp4.hpp>
 
auto tle = siderust::tle::Tle::parse(line1, line2);
auto prop = siderust::sgp4::Propagator(tle);
double epoch_jd = prop.epoch_jd_utc();
auto state = prop.propagate_at(epoch_jd + 360.0 / 1440.0);
// state.pos_km[3]  — TEME position, km
// state.vel_kms[3] — TEME velocity, km/s
