Requests for Additional Information are one of the most common causes of licensing delays for CubeSat and SmallSat missions. In 2026, RFIs increasingly reflect structural issues in filings rather than missing formalities. Understanding why RFIs are issued builds insight into how the FCC interprets risk and compliance readiness.

Most RFIs arise from inconsistencies between technical disclosures, unclear operational assumptions, or incomplete spectrum analyses. The FCC is particularly sensitive to discrepancies involving orbital parameters, power levels, and ground station usage, as these directly affect interference and safety assessments. Under Part 100, reviewers expect filings to function as internally coherent technical records rather than narrative proposals.

Preventing RFIs requires discipline across documentation, data management, and internal review processes. Operators that treat compliance as a continuous workflow rather than a submission event are better positioned to identify issues before filing. This approach not only reduces review time but also establishes credibility with the Space Bureau.

As regulatory scrutiny increases alongside launch cadence, minimizing RFIs becomes a competitive advantage for operators seeking predictable timelines.

This is especially timely when we see enforcement trends becoming increasingly common
