tle_catalog
(tles, sgp4_propagation=True, cartesian=True, kepler=False, propagator=None, propagator_options={}, propagator_args={})[source]¶ - Reads a TLE-snapshot file and converts the TLE’s to orbits in a TEME frame and creates a population file.
A snapshot generally contains several TLE’s for the same object thus will this population also contain duplicate objects. The BSTAR parameter is saved in field BSTAR
BSTAR
.Numerical propagator assumptions: To propagate with a numerical propagator one needs to make assumptions.
Density is :math:`5cdot 10^3 ;
- rac{kg}{m^3}`.
Object is a sphere
Drag coefficient is 2.3.
- param str/list tles
Path to the input TLE snapshot file. Or the TLE-set can be given directly as a list of two lines that can be unpacked in a loop, e.g.
[(tle1_l1, tle1_l2), (tle2_l1, tle2_l2)]
.- return
TLE snapshot as a Population
