This package ships the Navigation and Ancillary Information Facility's high precision Earth orientation parameters (EOP) [kernel](https://naif.jpl.nasa.gov/pub/naif/generic_kernels/pck/earth_latest_high_prec.bpc).

**This is not an official NAIF package**. It is an automatically generated mirror of the file so that it is
installable via `pip`.

Every night at around 2:15 AM UTC, the NAIF high precision Earth orientation parameters (EOP) kernel is downloaded and compared (via md5 checksum) to the current version of this package. If the checksums are different, a new package will be published.

## Installation

The latest version of the file can be install via pip:  
`pip install naif-eop-high-prec`

## Usage
```python
import spiceypy as sp
from naif_eop_high_prec import eop_high_prec

sp.furnsh(eop_high_prec)
```
