🐞 Problem
TLEs produced with propagate will have the eccentricity set to zero. This will crash some tools when loading the TLE, e.g. "Orbitron".
💡 Possible solutions
- Store the eccentricity set in the old TLE before propagation and set it again before writing the new TLE.
- Set a very small default eccentricity. The smallest encodable positive eccentricity is
0000001 / 1e-7 °.
