ISS Tracker


A web app that tracks the position of the International Space Station (ISS), and plots this on a map of the world.

It also locates the user’s current position, and calculates when the ISS will next fly overhead.

The clever bits come from the open notify API - this provides both the current position of the ISS and when it’ll next fly overhead based on the user’s location.

This is all plotted on a Google Map, and updated every few seconds.
