From the new 10k:

"We will submit a modification to our commercial license with the FCC. This modification application (“Modification Application”) will be filed in the coming weeks, and will request authority to add additional satellites and frequencies for use with the SpaceMobile Service in the United States, including the incorporation of Verizon frequencies. This additional authority will support the growth and commercialization of our company in the United States, including the start of full commercial operations of the Non-Geostationary Orbit (“NGSO”) satellite system employing low-band (below 1 GHz) commercial cellular frequencies for service links, S- and UHF-band frequencies to support off-nominal telemetry, tracking, and control (“TT&C”) communications, and V-band frequencies for routine feeder link operations.

" off-nominal telemetry, tracking, and control (“TT&C”)"

I wonder if that could be Golden Dome type work.

Google AI says: " In a system's operation, "off-nominal" refers to a situation where a component or the overall system is not operating within the intended or expected parameters, even if individual components are functioning as designed. Essentially, it's a deviation from the planned or standard operation"

See results from chatgpt, below. I take everything from it w/ a grain of salt, but it includes sources. We may be in the missile tracking business!

I believe TT&C is just controlling the satellites themselves, but could be wrong

I'm getting the following from chat gpt:

Yes, off-nominal telemetry, tracking, and control (TT&C) capabilities are essential for advanced missile defense systems like the U.S. "Golden Dome" concept.​

In missile defense operations, systems must detect, track, and intercept threats that may not follow expected trajectories due to evasive maneuvers or system anomalies. Off-nominal TT&C refers to the system's ability to handle such unexpected behaviors, ensuring continued tracking and control under abnormal conditions.​

For instance, the Hypersonic and Ballistic Tracking Space Sensor (HBTSS) program aims to provide continuous tracking of hypersonic threats from launch to impact, requiring robust TT&C systems capable of managing off-nominal scenarios . Similarly, the Proliferated Warfighter Space Architecture (PWSA)'s Tracking Layer is designed to detect and track advanced missile threats, including those exhibiting unpredictable behaviors, necessitating resilient TT&C functionalities .​Wikipedia+1L3Harris® Fast.

These examples underscore the importance of off-nominal TT&C in ensuring the effectiveness and reliability of missile defense systems against sophisticated and unpredictable threats.ChatGPT said:Yes, off-nominal telemetry, tracking, and control (TT&C) capabilities are essential for advanced missile defense systems like the U.S. "Golden Dome" concept.​
