Overview of Updates •Iterated draft findings and conducted follow-on work•Obtained feedback and input from full CSMAC•Added interview highlights as an appendix of the report•Updated and finalized report–Not too dissimilar to last presentation–UAS technical developments are evolving rapidly–Report is intended to give a generic snapshot of the current modelsavailable at this time, with notes and suggestions for how the exampletechnologies currently available for each model may be further refined,developed, and/or implemented for UAS operations Subcommittee Members •Dennis Roberson•Mariam Sorond•Bryan Tramont•NTIA Liaisons: Richard Orsulak,David Reed •Carolyn Kahn, Co-Chair•Andrew Roy, Co-Chair•Audrey Allison•Donna Bethea-Murphy•Michael Calabrese•Tom Dombrowsky•Mark Gibson•Mark McHenry•Carl Povelites Question: Unmanned Aircraft Spectrum a.The FAA has the responsibility of ensuring the safe integrations of allclasses of UAS into the national airspace, from small to large UAS.Spectrum to support command and control operations will be critical forthese emerging industry applications, to include urban air mobility andtranscontinental cargo delivery.b.What are appropriate models for ensuring timely and secure access to frequencies necessary to support UAS command and controlrequirements? What governance characteristics are important? Are thereliability issues to consider for this function? Is it a 3rd party frequencycoordinator model? c.What is the potential need to create an entity that supports and facilitatescollaboration across the disparate federal advisory committees for UAS?i.Develop alternative mechanisms and governance structures for such an entity Approach Initiated a concurrent, two-tiered approach:1.Identified options for spectrum access mechanisms for Unmanned Aircraft System (UAS)Identified possible solutions that may meet some/all of UAS requirements Evaluated in terms of advantages, disadvantages, and other observations2.Examine current state of the UAS environment and the committees supporting itLooked at the landscape of various organizations and their scope of activities pertaining to UAS spectrumConducted interviews with advisory boards and other organizations andexperts to supplement this information Approached this work to provide complementary, value-added contributions to ongoing activities in the UAS domain Schedule •Typically met on a recurring two-weekbasis•Held 30+ meetings via teleconference•Provided updates at full CSMACmeetings(January, April, and July 2020; Januaryand April 2021)•Conducted outreach–FCC TAC–RTCA–3GPP–FCC DAC–UAS ExCom–DoC Office of Space Commerce •Subcommittee kickoff: January 16,2020•Conduct interviews: February 2020 –September 2020•Analyze information and develop adraft report: August 2020 – January2021•Iterate draft findings and conductfollow-on work: January 2021 – March2021 CSMAC planned a staggered start this term in effort to help balance the workload across subcommittees Background: The UAS Environment •Dynamic state of development, innovation, and market evolution•UAS applications are inherently complex due to the wide variety of types, sizes,scale, applications, altitudes, and safety-of-life and safety-of-flight requirements•Regulatory structures are needed to support UAS growth and safe integrationinto the National Airspace System (NAS), which presents several policy andtechnical challenges•Need suitable spectrum infrastructure, such as spectrum access mechanisms andnecessary regulations, enabled by appropriate regulations for spectrum access•On a global basis there are disparities in spectrum regulations that would needto be addressed and/or accommodated to facilitate the expected internationalUAS market UAS Spectrum Access Models •Third-party coordinator•Terrestrial commercial wireless networks•Commercial satellite communications (SATCOM) networks•Unlicensed access•Dynamic spectrum access•Band partitioning The order of the spectrum access mechanisms presented below conveys no meaning or preference by CSMAC Third-Party Coordinator •An aviation spectrum expert third-party coordinator acts on behalf of the FCC and NTIA toissue the necessary license authorization to transmit to UAS providers on a demand basis toterrestrial ground stations dedicated to UAS CNPC links•Each UAS would be assigned one or more frequencies (including alternate channels) alongthe planned route they intend to fly•The assignment process would use some combination of automation and/or human in theloop, similar to how current aviation air-to-ground systems are currently managed in theVHF band for Controller Pilot Datalink Communications (CPDLC)–Both single and multiple third-party coordinators would be applicable for this model•Technology options- Certified aviation UAS CNPC systems•Existing examples of model- Used to assign aviation frequencies for CPDLC and flight testfunctions; proposed frequency management organization discussed in RTCA DO-362•Possible
