How To Install python3-jplephem on Debian 12
Introduction
In this tutorial we learn how to install python3-jplephem on Debian 12.
What is python3-jplephem
python3-jplephem is:
This package can load and use a Jet Propulsion Laboratory (JPL) ephemeris for predicting the position and velocity of a planet or other Solar System body. It currently supports binary SPK files (extension “.bsp”) like those distributed by the Jet Propulsion Laboratory that are:
- Type 2 - positions stored as Chebyshev polynomials, with velocity derived by computing their derivative.
- Type 3 - positions and velocities both stored explicitly as Chebyshev polynomials.
- Type 9 - a series of discrete positions and velocities, with separate timestamps that do not need to be equally spaced. Currently there is only support for linear interpolation: for Type 9 ephemerides of polynomial degree 1, not of any higher degrees.
Even if an ephemeris isn’t one of the above types, it is still possible to use jplephem to read its text comment and list the segments inside.
