What’s Happening

The FCC is updating its rules to address CubeSat proliferation. These include:

• New sub-band allocations for small satellites in S-, X-, and Ka-bands.
• Mandatory orbital debris mitigation plans, including active or passive deorbit within 5 years.
• More rigorous enforcement of real-time telemetry access and collision avoidance capability.

Why It Matters

CubeSat teams—especially those launching from the U.S. or using U.S. ground stations—face significantly higher licensing complexity. Missions with unclear deorbit plans or shared spectrum usage will likely be delayed or denied. The FCC’s goal is to prevent collisions and radio interference before they occur, which places new planning burdens on even single-satellite operators.

Technical Checklist

• Spectrum Readiness
• Identify primary and secondary bands for mission uplink/downlink.
• Run interference simulation with other users in shared bands.
• Select modulation and encoding that minimizes adjacent channel leakage.
• Debris Mitigation
• Provide time-to-deorbit modeling using NORAD or NASA tools.
• Include propulsion or passive re-entry strategy.
• Demonstrate collision avoidance (active sensors or SSA integration).
• Telemetry & Licensing
• Document real-time health & tracking system.
• File FCC Form 442 or 312 with spectrum + orbital parameters.
• Prepare risk mitigation report.

Scenarios & Recommendations

University Team

Challenge: Limited budget for propulsion and tracking. Recommendation: Use passive deorbit (drag sails); file early; partner with SSA providers for real-time tracking API access.

Constellation Operator

Challenge: Shared spectrum and tight orbital shells. Recommendation: Use frequency-hopping and inter-satellite scheduling. Pre-coordinate filings and deconflict frequencies using Astrolytics tools.

Commercial Payload

Challenge: FCC demands full end-of-life plan. Recommendation: Run simulations of natural decay; invest in minimal propulsion or magnetic torquers with clear reliability stats.
