Tyler Nighswander and Mike Nute have developed an incredible tool for detecting long-range missile and space launches by processing and visualizing ionospheric disturbances in GPS data. 

In one of the most fascinating and technically complex episodes of the ACW pod, Tyler and Mike join Jeffrey to talk about their wild new open-source intelligence tool, how it works, and what it means for missile and rocket observation. 

A visualization of their work can be seen here: https://twitter.com/ArmsControlWonk/status/1593452159365918722?s=20&t=hAI_EJvR8zCRMqj9u36yuw

And, of course, shout out to the ACW Slack Channel, wherin Tyler and Mike started this project.
