FCC Chair Calls on Agency to Update Orbital Debris Mitigation Rules

Mon, 03 Jun 2024 09:05:00 -0400

FCC Chairwoman Jessica Rosenworcel today called on the agency to update the Federal Communication Commission’s orbital debris mitigation rules to limit the risks posed by accidental explosions in space by adding a specific, quantitative metric that satellites must meet. If adopted, the updated rules would require satellite applicants to assess and limit the probability of debris-generating accidental explosions to be less 1 in 1,000 (0.001) for each satellite.

“We can no longer afford to launch new satellites into our skies without being thoughtful about space sustainability,” said Chairwoman Rosenworcel. “Our orbital debris mitigation efforts will help preserve the orbital environment to protect services we rely on and allow new services to be launched.”

The Third Report and Order circulated today is part of the Commission’s continuing efforts to mitigate the generation of orbital debris in light of the increasing number of satellites in orbit. The probability metric in the proposed rules is consistent with the U.S. Government Orbital Debris Mitigation Standard Practices and would provide satellite operators an objective and transparent benchmark for demonstrating as part of their applications to the Commission that they have assessed and limited the probability of accidental explosions during and after the completion of mission operations. The new requirement would be phased in one year after its publication in the Federal Register to allow potential applicants to prepare.

“The next World Radiocommunication Conference provides an opportunity to promote U.S. leadership in the growing space economy, as well as in next-generation communications services. With so much at stake, we will be relying on this advisory committee to help develop strong proposals for the Conference,” said Chairwoman Rosenworcel. “Jayne and Kim have both served on several previous iterations of this committee, including in leadership positions at the working group level, and between them, have attended eleven World Radio Conferences. This depth of experience will prove invaluable to the committee as it develops recommendations.”

Jayne Stancavage is the Vice President of Policy and Regulatory Affairs at Intel Corporation. She currently serves on the Board of Directors for both the United States Telecommunications Training Institute and the Open RAN Policy Coalition, and is also on the Global mobile Suppliers (GSA) Executive Committee. Ms. Stancavage received both her bachelor's and master's degrees in Political Science from the Massachusetts Institute of Technology.

Kimberly Baum is the Vice President of Spectrum Engineering and Strategy at Eutelsat Group. Her previous positions in the satellite industry include policy and engineering roles at Echostar Corporation, SES Americom, Motorola, and Astrolink. Ms. Baum began her career at the FCC, where she was an electronics engineer in the Office of Engineering and Technology and later in the International Bureau. Ms. Baum received her B.S. in Electrical Engineering from the Virginia Polytechnic Institute and State University and her M.S. in Electrical Engineering from the George Washington University.

The World Radiocommunication Conference Advisory Committee is chartered under the Federal Advisory Committee Act to provide to the FCC public views and recommendations in preparation for the next World Radiocommunication Conference.

The World Radiocommunication Conference is a treaty-level forum held by the International Telecommunication Union (a United Nations agency) every three to four years in which countries decide on the allocation of frequency spectrum to allow the deployment or growth of all types of radiocommunication services such as wireless, broadcasting, satellite, and aeronautical services. Gregory Baker in the Office of International Affairs serves as the Designated Federal Officer to the Committee.

Varifocal Lens

A varifocal lens is a camera lens with variable focal length in which focus changes as focal length (and magnification) changes, as compared to parfocal ("true") zoom lens, which remains in focus as the lens zooms (focal length and magnification change). Many so-called "zoom" lenses, particularly in the case of fixed lens cameras, are actually varifocal lenses.

The ABCs of Multimeter Safety from Fluke

Where safety is a concern, choosing a multimeter is like choosing a motorcycle helmet, if you have a “ten dollar” head, choose a “ten dollar” helmet. If you value your head, get a quality helmet. The hazards of motorcycle riding are obvious, but what’s the issue with multimeters? As long as you choose a multimeter with a high enough voltage rating, aren’t you safe? Voltage is voltage, isn’t it?

Not exactly. Engineers who analyze multimeter safety often discover that failed units were subjected to a much higher voltage than the user thought he was measuring. There are the occasional accidents when the meter, rated for low voltage (1000 V or less), was used to measure medium voltage, such as 4160 V. Just as common, the knock-out blow had nothing to do with misuse - it was a momentary high-voltage spike or transient that hit the multimeter input without warning.

To protect you against transients, safety must be built into the test equipment. What performance specification should you look for, especially if you know that you could be working on high-energy circuits? The task of defining safety standards for test equipment is addressed by the International Electrotechnical Commission (IEC). This organization develops international safety standards for electrical test equipment.

The good folks at Fluke have put together a truly informative and important guide on the subject. It describes in full detail the how's and why's of the subject and how to get the job done and stay safe every time. You can read the entire paper here.
