NAIF High Precision Earth Orientation Parameters (EOP) Kernel for SPICE

naif_eop_high_prec: NAIF High Precision Earth Orientation Parameters Kernel for SPICE

A Python package by the Asteroid Institute, a program of the B612 Foundation

This package ships the Navigation and Ancillary Information Facility's high precision Earth orientation parameters (EOP) kernel.

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 installed via pip:
pip install naif-eop-high-prec

Usage

import spiceypy as sp
from naif_eop_high_prec import eop_high_prec

sp.furnsh(eop_high_prec)

Acknowledgment

This project makes use of data provided and maintained by the Navigation and Ancillary Information Facility (NAIF).
