# Orbital Mean Elements (OMM)

SatKit supports propagating Orbital Mean-Element Message (OMM) records directly through `satkit.sgp4`.

OMM input is expected as a dictionary in the same structure used by CelesTrak or Space-Track responses.

```{eval-rst}
.. autofunction:: satkit.sgp4
   :no-index:
```

Use this page when your workflow starts from OMM/JSON records instead of Two-Line Elements.
