#### OMM support

Since version 2.0.0, support for the OMM format has been added, allowing the satellite orbital elements to be
provided a JSON-style format that handles NORAD ID's greater than 5 characters, and with less limits to
precision. Anywhere that a TLE is provided in the examples above, instead a python dictionary containing the
OMM data as described in the CCSDS blue book 502.0-B-3 can be provided. For example:

```python
omm = {
"OBJECT_NAME": "ISS (ZARYA)",
"OBJECT_ID": "1998-067A",
"EPOCH": "2026-08-19T03:31:32.932416",
