make_tle

ssapy.io.make_tle(a, e, i, pa, raan, trueAnomaly, t)[source][source]

Create a TLE from Kozai mean orbital elements

Parameters:

  • a (float) – Kozai mean semi-major axis in meters

  • e (float) – Kozai mean eccentricity

  • i (float) – Kozai mean inclination in radians

  • pa (float) – Kozai mean periapsis argument in radians

  • raan (float) – Kozai mean right ascension of the ascending node in radians

  • trueAnomaly (float) – Kozai mean true anomaly in radians

  • t (float or astropy.time.Time) – If float, then should correspond to GPS seconds; i.e., seconds since 1980-01-06 00:00:00 UTC

Notes

Dynamic TLE terms, including the drag coefficient and ballistic coefficient, are ignored in this function.
