My name is Stephen Mack, and for over a decade I have worked as an engineer and project manager in the commercial space industry. I have supported over a dozen geostationary and MEO launch campaigns and built satellite communication systems on six continents for a variety of customers and applications.

I have experience in many stages of spacecraft deployment including satellite operations, network design, link budgets, RF testing in a clean room environment, telemetry tracking and control, FCC and ITU licensing, in-orbit-testing, downlink operations performance, interference protection, and more.

In addition to RF engineering, I specialize in large scale data analytics to support spacecraft systems and broadcast services. Large data sets can be invaluable tools to determine the health of satellites and satellite ground infrastructure, quantify the quality of delivered services, and locate RF interference.

Currently, I am a Senior Staff Engineer of Space Systems at SiriusXM working with a brilliant team to ensure optimal service delivery to our millions of customers.

Professional Skills & Experience

Large projects don’t happen without carefully managing budgets, logistics, regulations, people, and strategic plans. I have over a decade of experience leading domestic and international teams of engineers to deliver superior satellite solutions.

software dev.png — **Network Design & Development**

I have been a major part of the design process for multiple satellite and terrestrial systems. My experience spans critical design review, clean room spacecraft testing, bring-into-use missions, Earth station & TT&C design, link budgeting, satellite operations, frequency planning, and much more.

I design, test, and carry out spacecraft procedures for routine and non-routine activities. I monitor many spacecraft performance metrics, provide health analysis, and watch for anomalies. My custom built analytics platform catches service-impacting events and notifies engineers within seconds.

**Satellite Ground Infrastructure Design & Integration**

I have built satellite ground infrastructure solutions on six continents for a wide range of services. Projects have ranged from large aperture antenna installations, broadcast system integration, earth station upgrades, and much more.

Satellite systems are regulated by the FCC in the United States and the ITU internationally. I have designed satellite uplink and downlink frequency plans, licensed US Earth Stations, licensed spacecraft with the FCC and ITU, and submitted comments to regulatory bodies to protect against unacceptable proposals.
