    ATTACHMENT A to FCC Public Notice DA 20-1243 Recommendations presented at October 20, 2020, Meeting of the World Radiocommunication Conference Advisory Committee 1 Maritime Aeronautical and Radar Services 2 WAC-23/0009 IWG-1/007 (09.23.20) UNITED STATES OF AMERICA DRAFT PRELIMINARY VIEW ON WRC-23 AI 1.6 AGENDA ITEM 1.6: to consider, in accordance with Resolution 772 (WRC-19), regulatory provisions to facilitate radiocommunications for sub-orbital vehicles; ISSUE: The United States requires a stable regulatory framework for radiocommunications for sub-orbital vehicles. BACKGROUND: Sub-orbital vehicles must operate in the same airspace as conventional aircraft while transitioning to and from space. Stations on board sub-orbital vehicles have a need for voice/data communications, navigation, surveillance, and telemetry and tracking and command (TT&C) applications to safely and effectively complete various mission requirements. The current regulatory provisions and procedures for terrestrial and space services may or may not be adequate for international use of relevant frequency assignments by stations on board sub-orbital vehicles. Resolution 772 (WRC-19) calls for studying spectrum needs and appropriate modifications to the Radio Regulations to accommodate sub-orbital vehicle radiocommunications requirements, excluding any new allocations or changes to the existing allocations in Article 51. There are several U.S. Commercial Space Transportation industry and government initiatives that could benefit from modification of the Radio Regulations as a result of these technical, operational, and regulatory studies. U.S. VIEW: To pursue studies called for by Resolution 772 (WRC-19) as a basis for possible new Radio Regulations to support the growing radiocommunications needs of sub-orbital vehicles.

  • Spacex Non-Geostationary Satellite System
    SPACEX NON-GEOSTATIONARY SATELLITE SYSTEM ATTACHMENT A TECHNICAL INFORMATION TO SUPPLEMENT SCHEDULE S A.1 SCOPE AND PURPOSE This attachment contains the information required under Part 25 of the Commission’s rules that cannot be fully captured by the associated Schedule S. A.2 OVERALL DESCRIPTION The SpaceX non-geostationary orbit (“NGSO”) satellite system (the “SpaceX System”) consists of a constellation of 4,425 satellites (plus in-orbit spares)1 operating in 83 orbital planes (at altitudes ranging from 1,110 km to 1,325 km), as well as associated ground control facilities, gateway earth stations and end user earth stations. The overall constellation will be configured as follows: SPACEX SYSTEM CONSTELLATION Parameter Initial Final Deployment Deployment (2,825 satellites) (1,600 satellites) Orbital Planes 32 32 8 5 6 Satellites per Plane 50 50 50 75 75 Altitude 1,150 km 1,110 km 1,130 km 1,275 km 1,325 km Inclination 53º 53.8º 74º 81º 70º This constellation will enable SpaceX to provide full and continuous global coverage, utilizing a minimum elevation angle of 40 degrees. 1 SpaceX will provision to launch up to two extra spacecraft per plane to replenish the constellation in the event of on-orbit failures. If a case arises wherein a spare is not immediately needed, it will remain dormant in the same orbit and will perform station-keeping and debris avoidance maneuvers along with the rest of the active constellation. Because these spare satellites will not operate their communications payloads, and the TT&C facilities communicate in turn with a fixed number of satellites at all times, the addition of spare satellites will not affect the interference analyses for TT&C operations presented in this application.

  • Fostering Commercial and Innovative Use of Radio
    www.citc.gov.sa Forward CITC issued its National Spectrum Strategy 2020-2025 (NSS) earlier this year. The NSS is aspired to “Unlock the potential of radiocommunication in Saudi Arabia for a smarter and safer future”. This is a holistic vision that outlines the potential of radio spectrum, to transform Saudi Arabia into a digital society by enabling a range of industries and sectors. The NSS vision aligns with the Saudi Vision 2030, by striving to ensure availability of radio spectrum to fulfill the needs of spectrum license holders and end-users alike, thus serving the interests of the whole nation. Three guiding principles will anchor CITC’s efforts towards fulfilling the National Strategy’s Vision: 1) Promote certainty and encourage investment through spectrum policies which anticipate and meet the needs of Spectrum users. 2) Efficiently and proactively seek out opportunities to optimize the benefits of spectrum for its users, maximizing its value to society. 3) Build strong relationships with all national stakeholders and regularly engage with them to ensure that spectrum management decisions reflect market dynamics. The NSS aims to promote innovation and commercial uses of spectrum to “Foster Commercial and Innovative Uses”, by increasing access to spectrum, ensuring management practices account for competitive dimensions, and tackling problem issues unique to the local ICT market context. It will push 5G+ deployment to position Saudi Arabia among leading nations in unlocking innovative high-performance use cases and applications and enable their deployment for vertical industries in both the public and in private sectors. The NSS also aims to enable applications and use cases that rely heavily on free/eased access to spectrum and unlocking spectrum related innovation to “Accelerate Innovation and Emerging Radio Technologies”.

  • United Kingdom Frequency Allocation Table (UKFAT) Details the Uses (Referred to As 'Allocations') to Which Various Frequency Bands Are Put to the UK
    1 Preface Introduction Radio waves, used by millions of people world-wide, do not conveniently stop at political or administrative boundaries. Without adequate planning and management, radio signals from different users and services would interfere with each other and radio could become useless as a means of communication. The United Kingdom Frequency Allocation Table (UKFAT) details the uses (referred to as 'allocations') to which various frequency bands are put to the UK. It also shows the internationally agreed spectrum allocations of the International Telecommunication Union (ITU). The ITU divided the world into three regions. These can be seen in the map below. The United Kingdom is within Region 1. Map of ITU-R Regions Changes to the international allocation of frequencies worldwide is agreed at World Radio Conferences and are incorporated into the Radio Regulations. The Radio Regulations have treaty status following ratification by ITU Member States, and contain the procedural regulations for notification, coordination and registration of radio frequencies so that harmful interference between radio stations of different countries is avoided. They also contain the international Table of Allocations for bands of frequencies to be used for providing specific radiocommunication services. These rules are detailed as footnotes in the Radio Regulations. Direct references have been made within the UKFAT to those footnotes, taken from the current ITU Radio Regulations, to the International Table which apply without qualification to the United Kingdom radio services or frequency bands concerned. All remaining International footnotes not specifically mentioned in the Table or in footnotes thereto do not therefore apply in the United Kingdom.

  • Introduction to International Radio Regulations
    Introduction to International Radio Regulations Ryszard Struzak∗ Information and Communication Technologies Consultant Lectures given at the School on Radio Use for Information And Communication Technology Trieste, 2-22 February 2003 LNS0316001 ∗ [email protected] 2 R. Struzak Abstract These notes introduce the ITU Radio Regulations and related UN and WTO agreements that specify how terrestrial and satellite radio should be used in all countries over the planet. Access to the existing information infrastructure, and to that of the future Information Society, depends critically on these regulations. The paper also discusses few problems related to the use of the radio frequencies and satellite orbits. The notes are extracted from a book under preparation, in which these issues are discussed in more detail. Introduction to International Radio Regulations 3 Contents 1. Background 5 2.

The converging computer and communications technologies add “intelligence” to old applications and generate new ones. The enormous impact of radio on the society continues to increase although we still do not fully understand all consequences of that process. There are numerous areas in which the radio frequency spectrum is vital. National defence, public safety, weather forecasts, disaster warning, air-traffic control, and air navigation are a few examples only.
