www. gvf. org Caspian Telecoms 2013 Satellite Interference: The Counter-Offensive Stéphane Chenard Executive Advisor on International Programme Development Global VSAT Forum
www. gvf. org The satellite industry. . . • Talks to everyone and goes everywhere -- TV, oil companies, defense, airlines, shipowners, Afghanistan, drought in Ethiopia, the Olympics, earthquake monitoring. . . all in a day's work -- Constantly on the run and looking for new markets • Resiliency, reliability, rapid response and continuity are cornerstones of the business -- Your requirements match a lot of our business priorities -- 99. 9999% reliable satellites, worldwide redundant networks -- Mission-critical to a lot of important people; backup plans embedded in contracts and licenses -- Key part of maritime and aeronautical safety networks • Small, autonomous, rapid-deployment systems are one of the major themes of competition -- Telecom infrastructure in areas with no power grid – done that; vast experience with Diesels and even hand cranks -- Industry-wide push to make antennas fit in hand luggage
www. gvf. org The Challenge • Financially Sustainable Pre-Positioning of… – Satcom Systems, – Satcom Services – Satcom Personnel • That Can Be Applied in Coordination with Local Suppliers • And That Can Be Repurposed to Support Medium-Long Term Development
www. gvf. org The Satcom Tools: GMPCS – Able to Be Procured in Advance of Disasters – Pre-Positioning is Key – Minimum of Training Needed Globalstar Iridium Thuraya Inmarsat Terre. Star
www. gvf. org One week of somebody's traffic
www. gvf. org The Satcom Tools: Fly-Aways 0. 5 to 10 Mbps $1, 500 -150, 000 3 -40 kg, travel as cabbin luggage auto-deploy and self-pointing
www. gvf. org The Satcom Tools: VSAT
The GVF Member Directory as a ‘Registry’ www. gvf. org • Hundreds of Thousands of ‘Pre-positioned’ Systems • Already ‘Sustainable’ Through Delivery of Services • Most Are Being Used to Support Development Apps • Contacts Available Through Searchable Directory • Designation Is Being Added to Indicate Companies • Willing to Stand-by as Pre-positioned System and Service Providers • MARCH 2011: UN-OCHA & GVF sign Mo. U to coordinate implementation of Disaster Preparedness Registry
Pre-Positioned Installers: www. gvf. org GVF Certified VSAT Installer Database • Contacts for Approx. 1, 500 Installers Worldwide; 4, 000 in training • Online, Public, Searchable Database • 1 -For-1 Offer to UN, Net. Hope/NGOs • Scholarship for Developing Nations • Used for Rapid Installation Support After Haiti Earthquake
www. gvf. org Pre-Positioned Satellite-Based ICTs: GVF Certified Installers – Public Database
www. gvf. org Horn of Africa • Some countries have restrictive & expensive VSAT licensing procedure • Many NGOs cannot afford it; it can impede relief efforts • GVF support includes: – Member company delegation – Information on comparative regulatory requirements – Member companies able to support service needs
www. gvf. org Why is Interference Increasing?
Characterizing Interference Types www. gvf. org Note: Percentages are based on Intelsat's experience but are indicative of hundreds of interference events experienced by the world’s satellite operators.
www. gvf. org • Satellite RFI: Breaking It Down Problems: • Solutions: 1. Improper Installations ü Training & Certification 2. Sub-Standard Equipment ü Product Quality Assurance 3. Unidentified Carriers ü Carrier ID 4. Wireless Interference ü Spectrum Initiative 5. Information Sharing ü SDA 6. Dysfunctional Networks ü Network Validation
Solutions – Key Points www. gvf. org ü Training & Certification – GVF Basic Installer Certification; GVF Advanced Installer Certification; Technology Specific Specialist Certification; all through online instruction & testing plus Hands-on-Skills -Test (HOST); Supplementary Instructor-led Classes; Training Centres Worldwide; 5, 000 technicians enrolled; NEW Auto-Deploy Operator Certification. ü Product Quality Assurance – GVF PQA Framework – A Strategic Plan for a Global Satellite Industry Arrangement to Facilitate Earth Station Design & Production; outsourced equipment type approvals through GVF MRA WG (Mutual Recognition Arrangement Working Group) appointed ATEs (Authorized Test Entities). ü Carrier ID – Technical feasibility established for Video Encoder implementation – now underway; GVF VSAT Group established in 2009; working with s. IRG (Satellite Interference Reduction Group) [www. suirg. org]; Root-Cause Analysis underway. ü Spectrum Initiative – IMT/BWA in C-band downlinks; WBU-ISOG endorsed GVF C-band paper – submission to national spectrum & inter-governmental proceedings; enforcement of WRC-07 C-band decision; now focused on WRC-12 & defence of Ku-band Ka-band. ü SDA (Space Data Association) – Automated space situational awareness system to reduce risks of on-orbit collisions and RFI [www. space-data. org] ü Network Validation – GVF piloting new Network Validation Service (2011) – network optimization and interference prevention; Report finalized and presented to network operator & end-user
Sub-Standard Equipment Trends www. gvf. org • Increasing Attempts by Inexperienced Manufacturers to Try Production of Transmiting VSAT Antennas • Designers often unaware of how accurately installers must align the antenna to prevent ASI and cross-pol interference • Now, Auto-Deploy Is Being Added to the Mix • Reduced Satellite Operator Provision of Type Approvals for VSAT Earth Station Equipment • Vacuum in Technical Know-How and Deployment of Systems That Spray Orbital Arc with Interference
www. gvf. org Product Quality Assurance. . . Overview • GVF Now Provides Outsourced Type Approvals • Intelsat and Eutelsat First to Embrace the Solution • GVF ‘Authorized Test Entities’ Available to… • • Assist Antenna Manufacturers with Design Conduct Type Approval Testing Using Satellite Operator Specs Provide Type Approval for Compliant Systems • Now: Global Product Quality Assurance Framework
www. gvf. org
Addressing Sub-Optimal Networks www. gvf. org • New: GVF Network Validation Service • Service Pilot: Team Evaluated VSAT Network in 27 Countries • Service Pilot Findings: Most/All Facets of Interference -Mitigation Initiative Would Help Network Performance • Report Submitted to Owner on How to Optimize Network and Prevent Interference • Network Validation as Latest Feature of Interference. Prevention Initiative
www. gvf. org • Satellite RFI: Breaking It Down… Again Problems: • Solutions: 1. Improper Installations ü Training & Certification 2. Sub-Standard Equipment ü Product Quality Assurance 3. Unidentified Carriers ü Carrier ID 4. Wireless Interference ü Spectrum Initiative 5. Information Sharing ü SDA 6. Dysfunctional Networks ü Network Validation
