Ligado Tells FCC That SkyTerra Next Proposal Won’t Cause Interference

Why It Matters

The FCC’s decision will shape how scarce L‑band spectrum is used for mobile satellite services, influencing broadband reach, GPS reliability, and market competition in the United States.

Key Takeaways

• Ligado seeks FCC license modification for SkyTerra Next L‑band payload.
• Iridium alleges spectrum hoarding and control transfer to AST SpaceMobile.
• GPS groups worry about interference to navigation services.
• Ligado claims compliance with FCC rules and retains spectrum control.
• Support from AST SpaceMobile, Viasat, MSSA could influence outcome.

Pulse Analysis

The L‑band, traditionally reserved for critical navigation and aeronautical services, is now a battleground for mobile satellite operators seeking to extend 5G connectivity. Ligado’s proposal to mount its SkyTerra Next payload on AST SpaceMobile’s LEO satellites promises a direct‑to‑device (D2D) architecture that could deliver broadband to remote U.S. regions where terrestrial networks falter. By leveraging existing coordination agreements, Ligado argues it can increase spectral efficiency without compromising the integrity of adjacent GPS frequencies, a claim that aligns with the FCC’s push for innovative spectrum use.

Opposition to the filing centers on two fronts: market concentration and technical risk. Iridium’s petition frames the partnership as a de‑facto transfer of Ligado’s licensed spectrum, potentially limiting competition in the emerging MSS market. Simultaneously, the GPS Innovation Alliance and agricultural equipment maker John Deere warn that intensified L‑band activity could degrade precision‑navigation signals vital for farming and autonomous systems. The FCC will need to balance these concerns against Ligado’s assurances of compliance, likely scrutinizing interference studies and the robustness of the coordination framework.

If approved, SkyTerra Next could accelerate the rollout of space‑based 5G services, offering a new layer of redundancy for consumers and enterprises alike. The collaboration also signals a broader industry trend toward integrating satellite capacity with terrestrial networks, fostering a more resilient communications ecosystem. Stakeholders such as Viasat and the Mobile Satellite Services Association have already voiced support, suggesting that the decision may set a precedent for future L‑band partnerships and shape the competitive dynamics of U.S. broadband provision.
