ARRL, AMSAT Seek Changes in FCC Orbital Debris Mitigation Proposals

FCC SealARRL Washington Counsel Dave Siddall, K3ZJ, and AMSAT Executive Vice President Paul Stoetzer, N8HM, on April 8, discussed with senior FCC International Bureau staff by telephone the FCC’s draft Report & Order (R&O) on mitigation of orbital debris (IB Docket No. 18-313). The amateur representatives told the FCC staff that “two aspects of the draft regulations are of particular concern…. and would seriously hinder amateur radio’s future operations in space, if adopted as proposed without the relatively minor changes that we propose.”

First, ARRL and AMSAT requested a revision to proposed language that otherwise would allow only private individual licensees to indemnify the U.S. for the operations of an amateur space satellite. ARRL and AMSAT requested that satellite owners be added to that provision. The amateur representatives, noting that amateur radio licensees may only be individuals under the amateur rules, stated that “[i]n no other service would an individual be required to personally make a similar indemnification” and that “it would be difficult to impossible to find an individual Amateur Radio licensee willing to bear that risk.”

Second, ARRL and AMSAT asked the FCC to delay by 3 years the proposed effective date of April 23, 2022, for a rule that would require satellite operators to certify that space stations “be designed with the maneuvering capabilities sufficient to perform collision avoidance” for spacecraft designed to operate above 400 kilometers in altitude. Citing the long lead times to design and construct Amateur satellites, ARRL and AMSAT suggested that a more reasonable date would be April 23, 2025 and noted that, based on recent past years, only an estimated 3-5 amateur satellites likely would be launched during the extra period.

“We do not disagree with the purpose of this requirement,” they told the FCC staff, but “the proposed effective date is unreasonable in the case of amateur radio satellites.” The new effective date “would allow time for amateur spacecraft designers to adapt to this new requirement,” they said.

Citing the value of amateur satellites to the development of the commercial small satellite industry, and student participation in such projects, ARRL and AMSAT said a strong and robust Amateur Satellite Service will help inspire future developments in satellite technology. The requested changes to the draft R&O would help ensure that amateur radio continues to have a future in space and contribute to the public interest on an educational, non-pecuniary basis.

The FCC is expected to consider the R&O at its April 23 open meeting.

AMSAT Files Comments in FCC Orbital Debris Mitigation Proceeding

Amateur Radio Satellites - To inspire, engage and educate the next generation

Amateur Radio Satellites – To inspire, engage and educate the next generation

AMSAT believes several of FCC’s proposed rule changes concerning orbital debris would have an extremely detrimental affect on the amateur satellite service.

The AMSAT News Service Reports:

The Federal Communications Commission has proposed several rules changes related to the amateur satellite service as part of a Notice of Proposed Rulemaking (NPRM) related to the mitigation of orbital debris. AMSAT believes several of these rule changes would have an extremely detrimental affect on the amateur satellite service and AMSAT’s ability to launch and operate new satellites, including AMSAT’s upcoming GOLF satellites.

Today, AMSAT filed comments on the proposed rulemaking. In the comments, AMSAT argues that amateur satellites often have longer mission lifespans than other small satellite missions and that the Commission should take a mission duration of 5 to 10 years into account when determining whether or not an amateur satellite will meet the orbital debris regulations by transferring to a parking orbit or re-entering the atmosphere within 25 years of mission completion. The current practice is to assume a “zero year” mission and to require that amateur satellites either transfer to a parking orbit or re-enter within 25 years following launch.

AMSAT also urged the Commission to consider alternatives to a proposed rule that would restrict satellites in Low Earth Orbit that plan to meet the orbital debris mitigation guidelines through atmospheric re-entry to altitudes of 650 km or less. AMSAT noted that, had this rule been in place, AO-85 and AO-91 would not have been able to be deployed in their current ellipitcal orbits with apogees of approximately 800 km, despite the fact that both of these satellites will re-enter within 25 years due to their low perigees. Additionally, AMSAT noted that current plans for the GOLF-1 satellite are to meet orbital debris mitigation guidelines through atmospheric re-entry by deploying a drag device that will ensure re-entry within 25 years despite deployment at an altitude of above 1,000 km. This proposed rule would prohibit GOLF-1’s deployment at that altitude.

The Commission’s proposed rules would also require that amateur satellite licensees indemnify the government against any claims made against the United States due to the operation of the satellite. AMSAT believes this proposal would end the ability of AMSAT, or any other entity in the United States, to launch and operate amateur satellites and urges the Commission to consider alternatives, such as establishing a fund to pay any such claims, noting that the likelihood of such a claim is low.

For amateur satellites with propulsion, the Commission proposes a rule that would require any command links as well as satellite telemetry be encrypted. While AMSAT understands and agrees that a satellite carrying a propulsion system must have an encrypted command link, the proposal to require all satellite telemetry be encrypted is unnecessary and counter to the spirit of the amateur service. AMSAT notes that open access to telemetry is expected of amateur satellites and is critical to the educational component of amateur radio satellites.

Finally, AMSAT proposes that the Commission exempt amateur space stations co-located on other spacecraft from the orbital debris mitigation regulations, including any indemnification rule. Noting that AMSAT has pursued opportunities to fly a payload as a rideshare aboard government or commercial satellites, AMSAT argues that, as the satellite’s owner will need to meet orbital debris mitigation requirements to obtain the license in the primary mission’s service, requiring the amateur licensee to meet the orbital debris mitigation requirements as well is redundant. AMSAT proposes that Part 97 be amended to state that amateur space stations co-located on spacecraft with space stations authorized under Part 25 of the Commission’s regulations (for commercial spacecraft) or by the National Telecommunications and Information Administration (NTIA) (for government spacecraft) are exempt from these regulations.
