Vlog 01 - Spectrum

Audacy Founder & CEO Ralph Ewig discusses how radio spectrum for space use has become a significant barrier to sustained industry growth, necessitating a new approach that replicates a terrestrial wireless network for space applications.

 

About Ralph Ewig

Dr. Ralph Ewig holds three aerospace degrees (BS/MS/PhD) from the University of Washington, and an MS in Business Management for experienced leaders (MSx) from the Stanford Graduate School of Business.  

He was a Project Engineer at Andrews Space (now Spaceflight), Partner/Chief Engineer at Holder Aerospace, Propulsion Engineer at AirLaunch, and Mission Operations Engineer at SpaceX for the first 3 flights of Dragon to the International Space Station (ISS). From there he transitioned to VP of Engineering at Aerojet Rocketdyne, and following his graduation at Stanford in 2015 took his role as founder & CEO of Audacy.

What is a Frequency Allocation?

Radio spectrum is a highly regulated, and ultimately finite natural resource. In space applications, regulations at both the national and the international level require proof that any new system will not interfere with existing uses. As the number of satellites increases, clearing that hurdle has become increasingly difficult, and today access to space-to-ground radio spectrum is a severe constraint to continued industry growth.

 The solution is a space-based relay system, acting like a cell phone network in space. This architecture can consolidate data traffic currently on space-to-ground frequencies with previously mostly unused space-to-space frequencies, and then downlink all of that data traffic from just a few locations.
