In the past 5 years, unprecedented expansion of satellite data and services has led to industry growth exceeding 35% a year. Ground based spacecraft communications solutions have reached their limits.

Without scalable connectivity, commercial space use remains severely constrained. With Audacy, operators benefit from increased revenue, anytime access, and turnkey operational simplicity; in any orbit and at any time.

User Need

Applications for Non-Geostationary Orbit spacecraft are growing rapidly. Yet current communications are ineffective and expensive, limiting commercial growth. Audacy provides continuous space / ground communications - any spacecraft, any orbit, any time.

Audacy is a fundamental enabler providing satellite payload tasking and payload data downlinking beyond anything previously available.

Any Time Access

Whether Audacy is your primary or complementary communications link, you benefit from any time forward tasking and continuous telemetry. Launch vehicles can be tracked far beyond the horizon, and reusable stages recovered with uninterrupted telemetry. Earth imaging operators can respond to customer requests with minimal lag time in both command and data retrieval.

Continuous telemetry enables trend monitoring; respond to system changes before they evolve to critical (or terminal) anomalies. Audacy can serve many users simultaneously. Operate large fleets without the need to coordinate multiple, tracking ground antennas. With no infrastructure to deploy, you are free to focus on what you do best: develop and operate cutting edge space vehicles.

Alternate Future

Open Earth Moon space to commercial use with a space based communications network.


Provide continuous communications paired with operational simplicity to spacecraft users worldwide.

Our Story

At the 1997 AIAA JPC conference in Seattle, Ralph Ewig reflected on the many presentations on human space travel. Frustrated with the endless debate, he committed to resolve the question independent of present-day engineering limitations. In 2006 he earned his PhD for identifying the optimum interplanetary spacecraft the laws of physics allow. The goal was set, but the path to reach it remained to be discovered. In 2005, NASA's Project Constellation set out to identify a roadmap for humans to the Moon, Mars, and beyond. Under that umbrella, Dr. Ewig developed an incremental approach to expand human activities throughout the solar system. A path was emerging, but as NASA leadership changed the funding evaporated. A fresh approach found its home at, an online collaboration platform for space enthusiasts to design a space architecture leveraging modular design, multi-body orbital mechanics, and in-site resource utilization of water & energy. However, funds were ultimately needed to transform vision into reality.

A year earlier, Microsoft co-founder Paul Allen financed the first commercial human spaceflight project. Under the banner of "SpaceShipOne, Government Zero", it became the starting roar of the commercial space industry. Dr. Ewig joined a consulting startup and gained recognition for cross-fertilization between established and "new space" organizations. Started in 2002, SpaceX further fueled the emerging industry, demonstrating commercial funding for colonizing Mars via disrupting the space launch market. "Commercial Space" was established as a viable funding platform, but a specific opportunity was still needed to build an architecture reaching beyond Low Earth Orbit. After joining SpaceX in 2010 to work in mission operations during Dragon's first flight to the International Space Station, frustration triggered another insight. The government's TDRSS communications relay used by Dragon was both ripe for disruption and a potential billion dollar ticket. What was needed now, was the business expertise to leverage that opportunity.

Following a stint of experiential learning as a freshly-minted corporate executive, Dr. Ewig entered Stanford's Sloan Program for experienced leaders (MSx) and set out to form a team in "The Startup Garage". The vision of a commercial building block for a sustained human space presence was contagious: "Team #48" rapidly grew to 7 graduate students from Stanford's engineering and business schools. The next step was to determine market fit and value. Leveraging strong industry networks, the team interviewed many spacecraft operators. Driven by the swelling wave of commercial space entrants ranging from startups to industry giants, the team identified a desperate need for space-based commercial spacecraft communications. However, the high capital investment required a substantial revenue potential; could the business scale? In the second quarter of the "Startup Garage" class sequence the team completed the design, capable of generating billions in annual revenue at current market pricing. As designed, Audacy is positioned to become a permanent building block that opens all of Earth-Moon space to commercial operation.
