ssapy_toolkit.IO.read_3le(data_file, makedf=True, verbose=False)

Parse a 3-line element (0/1/2) text file into a dict of lists or a DataFrame, and compute classical Keplerian elements at the TLE epoch.

All distances are meters (m), velocities m/s, angles rad/deg, times seconds.

Added fields (SI):

• mean_motion_rev_day, n_rad_s, period_s

• a_m, p_m, rp_m, ra_m, hp_m, ha_m

• inc_rad, raan_rad, argp_rad, M_rad

• E_rad/deg, nu_rad/deg, u_rad/deg

• ta_rad/deg, r_mag_m, v_mag_m_s

• r_eci_m_[x,y,z], v_eci_m_s_[x,y,z] (two-body, at epoch)

• epoch_gps (float seconds)

• a_sgp4, e_sgp4, i_sgp4, pa_sgp4, raan_sgp4, ta_sgp4, M_sgp4, n_sgp4
