TLE

✓ from satkit import TLE

✗ from satkit import Satellite

Creates a satellite from TLE and propagates to a time.

from satkit import Satellite, tle # Example: propagate a satellite from TLE line1 = '1 25544U 98067A 24001.00000000 .00000000 00000-0 00000-0 0 9999' line2 = '2 25544 51.6428 45.1234 0001234 100.0000 200.0000 15.50000000350000' sat = tle.TLE(line1, line2).to_satellite() # Propagate to a specific time (fractional day of year) state = sat.propagate(245.0) print(state.position, state.velocity)

Debug

Known issues

breakingIn v0.16, the 'propagate' method now returns a namedtuple instead of a tuple. Access fields by name (.position, .velocity) rather than indexing [0], [1].

fix

Use state.position and state.velocity instead of state[0] and state[1].

affects: >=0.16.0

gotchaTLE lines must be exactly 69 characters long (with newline stripped). Missing or extra spaces cause parsing errors.

fix

Ensure TLE lines are exactly 69 characters, including trailing spaces if needed.

affects: all

deprecatedThe function 'satkit.tools.propagate_tle' is deprecated in v0.16 and will be removed in v0.17. Use 'TLE.to_satellite().propagate()' instead.

fix

Replace with the new pattern: sat = TLE(line1, line2).to_satellite(); state = sat.propagate(time).

affects: >=0.16.0
