The FCC is currently considering an application by AST & Science, LLC for authorization to operate a total of 248 satellites in low-earth orbit. As part of this application, AST seeks to utilize the 430-440 MHz band for telemetry, tracking, and telecommand (TT&C) operations.
As part of the consideration process, the FCC is accepting public comment through July 21st. Over 600 individuals, many of them amateur radio operators, have already filed comments opposing AST’s request, as has AMSAT-DL. AMSAT is also preparing comments to be filed in this proceeding. Anyone may file or review comments through the FCC’s Electronic Comment Filing System (ECFS) at https://www.fcc.gov/ecfs/search/search-filings/results?q=(proceedings.name:(%2225-201%22)). The proceeding number is 25-201.
AMSAT-SM via Lars Thunberg SM0TGU has comment this application on 21 July:
Dear Sirs,
The AMSAT-SM amateur radio satellite group in Sweden is reaching out to share our concerns about the AST proposal to utilize the 430–440 MHz frequency band for Telemetry, Tracking, and Command (TT&C) operations. This portion of the spectrum is already designated as a primary allocation in Region 1 and is actively utilized by a range of users, including amateur radio operators and amateur satellite services.Amateur radio plays a key role in emergency communications and technical experimentation, while amateur satellites contribute significantly to educational and scientific pursuits. Approving AST’s application could interfere with these established uses and jeopardize their valuable contributions.
We respectfully urge the Commission to carefully evaluate the potential consequences of this proposal and to prioritize the protection of existing services. We also recommend considering alternative frequency bands better suited to AST’s operational needs.
Thank you for your time and consideration
Lars Thunberg – AMSAT-SM Sweden
