Realizing Resilient Tactical Networks with Maximum Government Control on High-Throughput Satellites
WHITE PAPER Realizing Resilient Tactical Networks with Maximum Government Control on High-throughput Satellites 1 Wide-beam connectivity is an essential aspect of military satellite communications and High Throughput Satellite (HTS) technology is proving to be ideally suited for many Government applications. While most satellite operators offer closed HTS architectures that are vendor-locked with very little control offered to users, the Intelsat Epic Next Generation (Epic) HTS architecture is enterprise- grade, open architecture and vendor-agnostic. Intelsat Epic allows Government and military access to bandwidth-efficient, higher data throughputs on a global-scale via a wide variety of user-chosen waveforms, modems and antennas. Intelsat is proud to present the next generation of satellite communications that features higher data throughput rates and security while offering cost-efficiencies across the board. Introduction High Throughput Satellites (HTS) have been the center of solutions. Interoperability between the various military attention for the past five years. It is important to note that branches, allied, and coalition forces continues to be a most of these systems have been purpose-built solutions to challenge. Finally, most military and government users require service homogeneous sets of users via closed architectures. operational coverage in remote and austere regions such Systems such as ViaSat Exede, Inmarsat Global Express, Hughes as deserts, jungles, and oceans—well outside of population Jupiter, and Eutelsat KA-SAT require new investments in centers for which these closed architectures are optimized. proprietary modem technologies and service architectures. These closed systems offer star-only connectivity and keep With the disconnects between these closed HTS solutions and quality of service control with the service provider, not the end the challenges faced by the Government, it is no wonder that users. -

Alexander, Editor Marshall Space Flight Center • MSFC, Alabama National Aeronautics and Space Administration Marshall Space Flight Center ° MSFC, Alabama 35812 August 1996 PREFACE The effects of the natural space environment on spacecraft design, development, and operation are the topic of a series of NASA Reference Publications currently being developed by the Electromagnetics and Aerospace Environments Branch, Systems Analysis and Integration Laboratory, Marshall Space Flight Center. This primer provides an overview of seven major areas of the natural space environment including brief definitions, related programmatic issues, and effects on various spacecraft subsystems. The primary focus is to present more than 100 case histories of spacecraft failures and anomalies documented from 1974 through 1994 attributed to the natural space environment. A better understanding of the natural space environment and its effects will enable spacecraft designers and managers to more effectively minimize program risks and costs, optimize design quality, and achieve mission objectives. .o° 111 TABLE OF CONTENTS -
Global Maritime Distress and Safety System (GMDSS) Handbook 2018 I CONTENTS
FOREWORD This handbook has been produced by the Australian Maritime Safety Authority (AMSA), and is intended for use on ships that are: • compulsorily equipped with GMDSS radiocommunication installations in accordance with the requirements of the International Convention for the Safety of Life at Sea Convention 1974 (SOLAS) and Commonwealth or State government marine legislation • voluntarily equipped with GMDSS radiocommunication installations. It is the recommended textbook for candidates wishing to qualify for the Australian GMDSS General Operator’s Certificate of Proficiency. This handbook replaces the tenth edition of the GMDSS Handbook published in September 2013, and has been amended to reflect: • changes to regulations adopted by the International Telecommunication Union (ITU) World Radiocommunications Conference (2015) • changes to Inmarsat services • an updated AMSA distress beacon registration form • changes to various ITU Recommendations • changes to the publications published by the ITU • developments in Man Overboard (MOB) devices • clarification of GMDSS radio log procedures • general editorial updating and improvements. Procedures outlined in the handbook are based on the ITU Radio Regulations, on radio procedures used by Australian Maritime Communications Stations and Satellite Earth Stations in the Inmarsat network. Careful observance of the procedures covered by this handbook is essential for the efficient exchange of communications in the marine radiocommunication service, particularly where safety of life at sea is concerned. Special attention should be given to those sections dealing with distress, urgency, and safety. Operators of radiocommunications equipment on vessels not equipped with GMDSS installations should refer to the Marine Radio Operators Handbook published by the Australian Maritime College, Launceston, Tasmania, Australia. No provision of this handbook or the ITU Radio Regulations prevents the use, by a ship in distress, of any means at its disposal to attract attention, make known its position and obtain help. -
