A program to calculate your ephemerides.
Displays time and astrological data (moon phases, positions of planets & celestial points in zodiac)
NASA/JPL SPICE Toolkit for C – patched for cross-platform compatibility
Astronomical library for JavaScript
JavaScript library to get Positions for Astronomical Bodies, including VSOP2013, VSOP2010, VSOP87, TOP2013, TOP2010, ELP2000-MPP02, ELP2000-82b, EPHASTER ephemerides and some home-grown ones (mgstat2023). Optimized for speed and size.
Quantum's interactive calendars, e.g. French Republican Calendar using historic equinox method for leap years.
ELP/MPP02 Lunar Ephemeris: C++ Implementation
Kosmorrolib, a library to calculate ephemerides.
Two Line Element position calculator using sgp4
Prototyping algorithms for pose estimation of the MoonRanger Lunar Rover. Flight code was based off these tests.
A project implementing algorithms from "Practical Astronomy with your Calculator or Spreadsheet" for astronomical calculations and data analysis.
Find planetary positions using NAIF SPICE Toolkit
Precision astronomical ephemeris for AI agents. An MCP server providing planetary positions via the Swiss Ephemeris.
Caelis Engine v2.2 is a Mathematical astronomical engine + symbolic interpretation system. Caelis Engine computes real planetary positions with professional precision (VSOP87, ELP/MPP02-LLR, IAU 2000B) and transforms them into a navigable symbolic framework — extended with secure AI-assisted interpretation.
ESA Intepolation Files made easy.
A "Many-to-One" Archaeoastronomy engine that converts cultural sky descriptions (Mayan, Chinese, Babylonian) into precise NASA-grade coordinates (J2000) and visualization scripts. Powered by Python, Skyfield (DE421), and Docker.
Astronomical cycle and aspect calculator — planetary transits, synodic cycles and harmonic index. Pure HTML/JS, no dependencies.
Add a description, image, and links to the ephemeris-calculations topic page so that developers can more easily learn about it.
