Спутник связи. Anik F2. [Редактировать]

Telesat Canada заказала Anik F2 в апреле 2000 года. Спутник должен предоставить услуги фиксированной связи, включая доступ в интернет и должен предоставить мультимедия услуги в Северной Америке.  Спутник использует ксеноновые двигатели для коррекции орбиты. 

Хронология работы аппарата

# Дата Комментарии
1 Октябрь 2011 года Отключалось обслуживание клиентов из-за сбоя бортового программного  обеспечения (БПО) управления вращением солнечных батарей. Вещание восстановлено через несколько часов после перезагрузки БПО.

A l a s k a Telephone Association Michael Garrett President 201 E. 56^*^ Avenue, Suite 114 Anchorage, AK 99518 (907) 563-4000 www.alaslotel.org Christine O'Connor Executive Director December 2, 2014 National Telecommunications and Information Administration U.S. Department of Commerce 1401 Constitution Avenue NW Room 4898, Attn: Arctic NOI Washington, DC 20230. RE: Telecommunications Assessment of the Arctic Region, Notice of Inquiry Docket No. 140925800-4800-01 Dear Sir and/or Madam, Alaska Telephone Association appreciates the work NTIA is doing to assess communications in the Arctic and the opportunity to respond to the Notice of Inquiry. ATA is composed of the local, long distance and wireless telecommunications companies serving Alaska. Our members serve Alaska's communities throughout the state from the Arctic to the Panhandle to the Aleutian Chain. We submit this response to the questions posed in the NOI. ATA member companies are experts in telecommunication and broadband services in Arctic Alaska and have a long, successful history of providing advanced services in these extremely remote, sparsely populated areas. They support commercial, residential, governmental and public safety users in very difficult geographic and climactic conditions. Our companies are committed to continuing to provide advanced telecommunications services and are striving together to identify solutions to major obstacles. The Alaska Broadband Task Force Report documented the gaps that exist in delivering robust broadband services across Alaska, and we encourage the NTIA to take note of the Task Force's Report and recommendations for the State of Alaska.^ A major challenge to providing broadband in the Arctic is a lack of middle mile infrastructure. Currently, providers must use extremely limited, costly satellite middle mile service to serve large portions of Alaska. The high cost and capacity constraints imposed by satellite transport require providers to offer users very limited bandwidth with stringent usage allowances. It is crucial that investment be targeted to build sufficient, affordable middle mile infrastructure in the Arctic and across Alaska. When providers are able to access middle mile facilities at reasonable costs, they will be able to offer affordable broadband service to all users, which will be critical for implementation of any Arctic Policy initiatives. Without affordable, high capacity middle mile, Alaskan communities will never have adequate broadband services, much less service reasonably comparable to that available in urban areas of the United States.^ The lack of adequate, affordable middle mile creates an adoption barrier for residents in Arctic Alaska. The extreme high cost of middle mile translates to either a complete lack of service or high rates for broadband service. High rates mean residents struggling with limited economic opportunity and high poverty rates are unable to afford broadband. Until the middle mile problem is solved, prices cannot come down and adoption rates are unlikely to improve. ATA cautions policy makers against adopting satellite technology as a quick fix to Alaska's middle mile challenge. While satellite service is better than none, it should not be the end solution. Alaskan telecommunications companies have conducted extensive research and determined sufficient satellite capacity ' The Broadband Task Force Report can be downloaded at http://www.alaska.edu/oit/bbtaskforce/homepage.html ^ See Section 254(b)(3) of the 1996 Telecom Act. 1 does not exist over Alaska to meet current or projected user needs.^ Our goal is robust service for our communities comparable to what is available elsewhere in the country. Satellite technology is beset with technical problems such as latency, weather degradation and geographical impediments. Alaskans need robust, terrestrial middle mile infrastructure to ensure they receive comparable services to the rest of the country. Another major obstacle to investment in broadband infrastructure is uncertainty in the mechanisms which should support that investment. As eligible telecommunications carriers in high cost areas, Alaska providers serving the Arctic are eligible to receive support from the universal service fund. They use USF support combined with private capital to deploy and operate broadband infrastructure. Extreme high costs mean deployment has moved slowly, but progress has been made in upgrading last mile networks to bring broadband to users. However, recent FCC efforts toward reform of the universal service fund have created great uncertainty for Alaska's carriers. Initial reform efforts penalized Alaska's providers'* and a long-term support mechanism for rate of return and competitive carriers has not been identified. Deployment of broadband infrastructure requires long-term investment, which cannot be made without reasonable certainty of funding. Continuing uncertainty in universal service fund support mechanisms is impeding ...
