Crate rust_jpl 

Rust JPL Ephemeris Reader

A Rust library for parsing NASA JPL ephemeris data, providing precise planetary positions based on Julian dates. This library supports DE441 and other JPL ephemeris formats.

Features

• Planetary Positions: Accurate positions of celestial bodies for a given Julian date
• Ephemeris Data: Utilization of DE441 file for precise planetary information
• Time Conversions: Conversion between Julian dates and calendar dates
• Lunar Ephemerides: Specific data for accurate moon-related calculations
• Solar System Dynamics: Detailed data for understanding solar system dynamics

Example

use rust_jpl::{Ephemeris, JulianDate};

// Initialize ephemeris with configuration
let eph = Ephemeris::new("config.toml")?;

// Convert calendar date to Julian date
let jd = JulianDate::from_calendar(2024, 1, 15, 12, 0, 0.0)?;

// Get planetary position
let position = eph.get_position("Earth", jd)?;
println!("Earth position: ({}, {}, {}) AU", position.x, position.y, position.z);
