Issue 4: From the Guest Editor: Satellite Communication in Canada

Welcome to the 4th edition of the Online Journal of Space Communications. This issue focuses on Satellite Communications in Canada, one of the leading countries in the development and use of Satellite Communications. In this issue you will discover why Satellite Communications is so important to Canada, what its major programs are, who the main players are and what the future directions are likely to be

The Role of Partnerships Government/Industry/International

Much of Canada\u27s involvement in space activities, particularly in the earlier years, related to its interest in satellite communications as a means to provide equitable access by all Canadians to telecommunications services. It also provided the impetus for Canada signing a cooperative agreement with ESA. There are a number of firsts in satellite communications to which Canada can lay claim. However the environment for space communications systems and services has changed dramatically and continues to change due to factors such as global deregulation, rapid advance of telecommunications technology, industrial consolidation and intense competition

Market Analysis

Canadian space companies have developed impressive and globally competitive competencies in some niche areas of satellite communications. This has allowed them to be very successful in domestic and export markets. In fact, 63% of total 2000 revenues of $1.4 billion were from Telecommunications. Satellite communications can be considered the cornerstone of the Canadian space industry at large

Industry Capabilities and Services

Space Communication technologies have provided the world with satellite communications and global satellite navigation infrastructures that have become strategic assets for the economic, political, and military sectors of countries around the world. Their omnipresence in our everyday lives and their significant role in world commerce, security and humanitarian operations such as Search and Rescue have made telecommunications and global navigation satellites indispensable

The crucial computing support from all WLCG partners is acknowledged gratefully, in particular from CERN, the ATLAS Tier-1 facilities at TRIUMF (Canada), NDGF (Denmark, Norway, Sweden), CC-IN2P3 (France), KIT/GridKA (Germany), INFN-CNAF (Italy), NLT1 (Netherlands), PIC (Spain), ASGC (Taiwan), RAL (UK) and BNL (USA), the Tier-2 facilities worldwide and large non-WLCG resource providers. Major contributors of computing resources are listed in Ref.[52].Searches for new resonances in the diphoton final state, with spin 0 as predicted by theories with an extended Higgs sector and with spin 2 using a warped extra-dimension benchmark model, are presented using 139 fb(-1) of root s = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. No significant deviation from the Standard Model is observed and upper limits are placed on the production cross-section times branching ratio to two photons as a function of the resonance mass.ANPCyTYerPhI, ArmeniaAustralian Research CouncilBMWFW, AustriaAustrian Science Fund (FWF)Azerbaijan National Academy of Sciences (ANAS)SSTC, BelarusConselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Natural Sciences and Engineering Research Council of Canada (NSERC)NRC, CanadaCanada Foundation for InnovationCERNANID, ChileChinese Academy of SciencesMinistry of Science and Technology, ChinaNational Natural Science Foundation of China (NSFC)Minciencias, ColombiaMinistry of Education, Youth & Sports - Czech Republic Czech Republic Government Czech Republic GovernmentDNRF, DenmarkDanish Natural Science Research CouncilCentre National de la Recherche Scientifique (CNRS)CEA-DRF/IRFU, FranceSRNSFG, GeorgiaFederal Ministry of Education & Research (BMBF)HGF, GermanyMax Planck SocietyGSRI, GreeceRGC, ChinaHong Kong SAR, ChinaIsrael Science FoundationBenoziyo Center, IsraelIstituto Nazionale di Fisica Nucleare (INFN)Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of ScienceCNRST, MoroccoNetherlands Organization for Scientific Research (NWO)Netherlands GovernmentRCN, NorwayMinistry of Science and Higher Education, PolandNCN, PolandPortuguese Foundation for Science and TechnologyEuropean CommissionMNE/IFA, RomaniaJINRRussian FederationNRC KI, Russian FederationMinistry of Education, Science & Technological Development, SerbiaMSSR, SlovakiaSlovenian Research Agency - Slovenia MIZS, SloveniaDSI/NRF, South AfricaSpanish GovernmentSRC, Sweden Wallenberg Foundation, SwedenSERI, Switzerland Swiss National Science Foundation (SNSF) Canton of Bern, Switzerland Canton of Geneva, SwitzerlandMinistry of Science and Technology, TaiwanMinistry of Energy & Natural Resources - TurkeyUK Research & Innovation (UKRI)Science & Technology Facilities Council (STFC)United States Department of Energy (DOE)National Science Foundation (NSF)BCKDF, Canada CANARIE, Canada Compute Canada, Canada CRC, CanadaCOST, European Union European Research Council (ERC) ERDF, European Union Horizon 2020, European Union Marie Sklodowska-Curie Actions, European UnionFrench National Research Agency (ANR)German Research Foundation (DFG)Alexander von Humboldt FoundationHerakleitos programme - EU-ESF, Greece Thales Group Aristeia programme - EU-ESF, Greece Greek NSRF, GreeceBSF-NSF, IsraelGerman-Israeli Foundation for Scientific Research and DevelopmentNorwegian Financial Mechanism 2014-2021, NorwayLa Caixa Banking Foundation, Spain CERCA Programme Generalitat de Catalunya, Spain PROMETEO Programme Generalitat Valenciana, Spain GenT Programme Generalitat Valenciana, SpainGoran Gustafssons Stiftelse, SwedenRoyal Society of LondonLeverhulme Trus
