tle2czml

A module that converts a TLE to a czml file that can be ingested by Cesium. This is thanks to satellite.js


Note: This module takes in a .tle and writes out a .czml file and sets orbit path for 5 days. Feel free to change this if you wish. I believe it is suggested to use it for only 3days.

Install:

``bash
npm install tle2czml
`

How to use:

`js
const tle2czml = require('tle2czml');

tle2czml.getCoords('25544.tle');
`

Output:

A .czml file with the same name as .tle passed in

Example of 25544.tle contents:
