node-sgp4
SGP4 is one of five simplified pertubation models used to calculate various orbital information about satellites. This library was ported from python-sgp4 and uses some functions from satellite-js to convert coordinates.

Installation
npm install sgp4
Example | Google Maps Demo
An example is provided in the top directory named example.js
. To run the example, simply use the command node example
. This example program will print the latitude and longitude of the ISS at the current point in time based off of TLE data from 14 September 2015.
Notes
Most of the methods are self explanatory. The example does a great job of showing how to get different types of coordinates. There are many functions at the bottom of sgp4.js that allow conversion between different coordinate models.
