Trạm điều khiển vệ tinh Vinasat1
- Một kỷ nguyên thông tin mới cho Việt Nam sẽ mở ra với việc vệ tinh VINASAT-1 được phóng lên quỹ đạo vào ngày 12/4 tới đây. Lễ phóng vệ tinh sẽ được truyền hình trực tiếp về VN lúc 5h30 sáng ngày 12/4/2008.
Television broadcasting is expected to be the initial service offered by the country's first satellite, Vinasat-1, once it is sent into orbit in May, 2008, tapping into the multi-billion dollar satellite industry.
Due to delays in building and launching the satellite, Vinasat's management company Vietnam Telecoms International, is updating information on customer demand and the regional business environment to gain an idea of the current demand for satellite services and set a quotation for services.
The satellite is set to have 20 transceivers with a 15-year life span. Vinasat-1 will offer a dedicated network catering for national defense and lease transmission capacity to enterprises that have a wide domestic and foreign branch network and a virtual private network including, transponding mobile base transceiver stations and telephone switchboards.
The provider will either lease a transceiver or full package service to end-user customers. The company also offers basic point-to-point network, very small aperture terminal (VSAT), internet broadband, and high definition television.
VTI official Nguyen Quang Hung said television broadcasting options will be the satellite's main service following world trends.
"The number of local television [stations] will increase in the future instead of broadcasting through narrow covered equipment on earth. The foreign television [stations] will also have the chance to broadcast their programmes in Vietnam through Vinasat-1," said Hung.
Other enterprises with large branch networks in banking, education, health and mobile services will also be key satellite customers.
"The price of services will be calculated on a reasonable and competitive basis," Hung said.
According to the VNPT Group, there are already number of customers registered for the services including the ministries of National Defense, Public Security and other telecom operators including EVN Telecom, SPT and Viettel.
The VNPT Group selected the US Lockheed Martin Commercial Space Systems as the main contractor of Vinasat-1.
Lockheed Martin Commercial Space Systems then awarded a contract to Integral Systems to provide primary and backup satellite-control systems and has subcontracted SES Astra Techcom to deliver two satellite antenna systems in Vietnam for Telecommand, Telemetry and Control and training courses to Vietnamese satellite operating personnel.
Global satellite industry revenues posted annual average growth of 6.7 per cent for the period 2000-2005, reaching $88.8 billion in 2005. Of these, satellite services are becoming important with $52.8 billion, or 60 per cent, of the total satellite industry revenue in 2005. The ground equipment segment made up 28 per cent, ranking the second largest.
Satellite services include VSAT, remote sensing, transponder agreement, DTH television, DARS, broadband, mobile telephone and data. Of which DTH television, DARS and broadband created the largest ratio of revenue of the total service revenues, reaching $41.3 billion in 2005.
Vietnam's second and fourth largest state-owned commercial banks in terms of total assets, Vietcombank and Incombank, have jointly signed a credit sponsor agreement with VNPT group to provide a loan worth $146.1 million for the Vinasat1 project.
Vinasat-1 will cover Japan, China, Korea, India, the ASEAN region, Australia, the East (South China) Sea and a part of Myanmar. A satellite control station will be established in Hoai Duc district, northern Ha Tay province, and a standby facility will be built in southern Binh Duong province's Ben Cat district.
