The Federal Communications Commission (FCC) has officially broadened the spectrum allocation for commercial launch applications, aligning with a legislative mandate enacted earlier this year.
On December 31, the FCC released a report and order specifying the allocation of the 2360-2395 megahertz frequency band for communication with commercial launch and reentry vehicles. This decision comes as part of the implementation of the Launch Communications Act (LCA) of 2024, which required the FCC to make additional spectrum available within 90 days of the bill’s enactment.
Previously, the FCC had designated two frequency bands—2025-2110 and 2200-2290 megahertz—for similar uses, restricted to uplinks and downlinks, respectively. The latest allocation enables both uplink and downlink communications within the 2360-2395 megahertz range, addressing the increasing demand for bandwidth due to rising launch activities.
Jessica Rosenworcel, the chairwoman of the FCC, emphasized the importance of this expansion, stating, “By identifying more bandwidth for vital links to launch vehicles, we are making it simpler for new competitors to get consistent access to the spectrum they need.” This move is expected to facilitate a more competitive environment for commercial space operations, ensuring sustained growth and innovation.
However, the allocation is not without challenges. One significant concern involves potential interference with existing operations in the band, particularly for aircraft and missile testing communications. The Aerospace and Flight Test Radio Coordinating Council has highlighted these potential conflicts, although the FCC has clarified that launch communications will operate on a secondary basis, requiring measures to avoid disrupting aerospace testing.
Both SpaceX and Virgin Galactic have already utilized portions of this band, with SpaceX employing it for Falcon Heavy and Starship/Super Heavy launches. Virgin Galactic reported having used the band for several suborbital spaceplane launches without receiving interference complaints.
In response to these developments, the FCC’s report and order also introduce a new licensing framework under part 26. This framework aims to streamline the application process, replacing the need for special temporary authority for each launch. This regulatory refinement promises greater certainty and efficiency for commercial space endeavors in the United States.
The FCC’s decision to allocate additional spectrum for commercial launches marks a significant step in supporting the burgeoning space industry. By addressing the need for more bandwidth and refining regulatory frameworks, the FCC is fostering an environment conducive to innovation and competition. This strategic allocation is poised to enhance the efficiency and reliability of commercial space operations, paving the way for future advancements in space exploration and technology.
