Amateur Satellite Frequency Coordination Request1
Amateur Satellite Frequency Coordination Request — Page 1 AMATEUR SATELLITE FREQUENCY COORDINATION REQUEST1 1. Amateur-satellite service. Amateur stations meet the requirements of the radio regulations2, RR 1.56. and 1.57. RR 1.56 amateur service: A radiocommunication service for the purpose of self- training, intercommunication and technical investigations carried out by amateurs, that is, by duly authorized [licensed] persons [individual natural people] interested in radio technique solely with a personal aim [for themselves] and without pecuniary interest [compensation]. (NOTE: Explanatory terms in brackets are not part of the treaty text.) RR 1.57 amateur-satellite service: A radiocommunication service using space stations on earth satellites for the same purposes as those of the amateur service. Before asking for help from IARU with frequency coordination in the amateur-satellite service, make sure that your proposed operation meets the treaty requirements. NOTE: “Without pecuniary interest” means that you may accept free will donations of goods and services, that is, with nothing required in return. You may not sell services or data to anyone for any reason. Ultimately, the decision of whether the proposed operation is appropriate for the amateur- satellite service rests with your country’s administration (your national telecommunication regulator). Therefore, before sending your frequency coordination request to IARU, we suggest that you consult with your administration to determine whether the amateur-satellite service or another radiocommunication service is appropriate for your operation. 2. Self coordination. For over 100 years, amateur radio operators have maintained an effective tradition of self-regulation. Amateurs are expected to coordinate their use of frequencies. -

Soft Passivation of Spacecraft Pressure Vessels
First Int'l. Orbital Debris Conf. (2019) 6042.pdf Soft Passivation of Spacecraft Pressure Vessels William P. Schonberg Civil Engineering Department, Missouri University of Science & Technology, Rolla, MO 65409 [email protected] ABSTRACT Most spacecraft have at least one pressurized vessel on board. In addition to a hole, it is possible that a pressure vessel may experience catastrophic failure as a result of a hypervelocity impact, such as by a micrometeoroid or space debris particle. If a tank rupture were to occur on-orbit following a micrometeoroid or orbital debris particle impact, not only could it lead to loss of life, but it would also generate a tremendous amount of debris that could compromise future space assets working in similar orbits. As a result, NASA and other space agencies have put in place design requirements to prevent additional sizable debris from being created in the event of a catastrophic pressure vessel failure. These requirements typically state that stored energy devices are to be passivated at the end of a spacecraft’s mission or useful life. Since many spacecraft designs are not be able to comply with some aspects of those requirements, an alternative, so-called “soft passivation” option was added. This paper provides a summary of a project performed with the intent of providing guidelines and considerations that can be used by satellite programs to help satisfy passivation requirements using a “soft passivation” approach, that is, when not able to perform complete hard passivation. 1 INTRODUCTION Most spacecraft have at least one pressurized vessel on board. For robotic spacecraft, it is usually a liquid propellant tank. -
The Disposal of Spacecraft and Launch Vehicle Stages in Low Earth Orbit
THE DISPOSAL OF SPACECRAFT AND LAUNCH VEHICLE STAGES IN LOW EARTH ORBIT Nicholas L. Johnson NASA Johnson Space Center, Houston, TX, USA, [email protected] ABSTRACT restricting the orbital lifetimes of spacecraft and launch vehicle stages residing in or passing through LEO after Spacecraft and launch vehicle stages abandoned in mission termination. The primary purpose of this action Earth orbit have historically been a primary source of is to enhance space safety by significantly constraining debris from accidental explosions. In the future, such the potential of future accidental collisions, which in satellites will become the principal cause of orbital turn could result in the creation of large numbers of new debris via inadvertent collisions. To curtail both the orbital debris. near-term and far-term risks posed by derelict spacecraft and launch vehicle stages to operational space systems, Not surprisingly, the majority of mass in Earth orbit numerous national and international orbital debris today (> 5000 metric tons) resides in non-operational mitigation guidelines specifically recommend actions spacecraft and launch vehicle stages. This mass also which could prevent or limit such future debris represents the largest segment of cross-sectional area, generation. Although considerable progress has been i.e., collision hazard, for future debris generation. In the made in implementing these recommendations, some 1980’s, early National Aeronautics and Space changes to existing vehicle designs can be difficult. Administration (NASA) projections of the potential Moreover, the nature of some missions also can present long-term growth of the Earth’s satellite population technological and budgetary challenges to be compliant identified the increasing amount of mass in Earth orbit with widely accepted orbital debris mitigation measures. -

Working Document on Developing an ITU-R Small Satellite HB WP 4A
Radiocommunication Study Groups Source: Document 4A/TEMP/47 Annex 13 to Document 4A/246-E Subject: Small Satellite Handbook 9 March 2021 English only Annex 13 to Working Party 4A Chairman’s Report WORKING DOCUMENT ON DEVELOPING AN ITU-R SMALL SATELLITE HANDBOOK Based on contributions 4A/183 and 4A/239, Working Party (WP) 4A have prepared this draft revision to Annex 14 of the WP 4A Chairman’s Report (Document 4A/155) for the Small Satellite Handbook, following offline consultation as directed by the first Plenary session of WP4A. Annex 14 of document 155 contained only the skeleton of the handbook and all content to the various sections has been added from contributions 4A/183 and 4A/239 to this meeting. This text is shown as clean text in the attached document. Text shown with revision marks indicates changes during the informal consultations during the WP 4A meeting. The attached updated document is proposed to remain as a working document towards Small Satellite Handbook. More contributions to further progress the work on this handbook is encouraged for the future meetings of WP 4A. Editorially, in further work, use of recognized ITU terminology as defined in the ITU-R literature (e.g., Radio Regulations, ITU-R V-series Recommendations and/or Rec. ITU-R S.673) should be ensured to be used throughout this handbook. Considering that this handbook is still at an early stage of development, it may be premature to consider liaison statement to other working parties including reply liaison statement to WP 5A in response to their liaison statement 4A/42 and to WP 7B in response to their liaison statement 4A/69.
