VIETNAM Ë HaNoi Capital Vietnam is located in South-East Asia Area: 329,560 km2 (65th) Population: 2005 estimate 83,535,576 (13th) Climate: The climate is tropical and monsoonal; humidity averages 84 percent throughout the year. Topography: Three quarters of Vietnam's territory consist of mountains and hills. Administrative Units: Vietnam is divided into 64 provinces and cities Natural hazards: typhoons, flash flood; extensive flooding in the Mekong River Delta, drought in the centre of VN. Vietnamese cosmonaut • Space Technology has been introduced into Vietnam since 1980 by the UNDP’s projects to promote utilization satellite data in survey, and particularly by the joint Soviet Union Vietnam space flight. • Cosmonaut Pham Tuan joined People’s Army of Viet Nam Air Force since 1965. On the night of December 27, 1972, he shot down a US B-52 bomber circling over the Ha Noi sky, becoming the first person ever to do so. • With his great military exploit, Pham Tuan was selected to take part in the joint Vietnam–Soviet Union flight for the study of space for peaceful purposes. Pham Tuan and Eugene H Trinh Pham Tuan and Eugene HC Trinh • • • • • Born on February 14, 1947, in Thai Binh province (VN). Pham Tuan along with soviet cosmonaut Viktor Gorbatko was launched from Baikonur Cosmodrome on July 23, 1980 on board Soyuz 3. They were to service the Salyut 6 station. During his time in orbit Pham Tuan performed experiments on the melting of mineral samples in microgravity and carried out plant experiments on azola. The National Centre for Scientific Research of Vietnam( now renamed VAST) was responsible to prepare these experiments. Was the first Vietnamese cosmonaut, the first Asian in the space. Currently, Lieutenant General Pham Tuan is the Head of National Defense Industry Agency. • • • • • • Born on September 14, 1950 in Sai gon (now renamed as H.C.M City). He was raised from the age of two in Paris (France) and has lived in United States since 1968. Doctorate of Philosophy in Applied Physics from Yale University in 1977. Was payload specialist crew member on the STS-50/US Microgravity Lab1 Space shuttle in 1992. Was the first Vietnamese-American cosmonaut. Published over 40 reviewed articles and authored as many conference papers in the areas of Fluid Dynamics, Acoustics, Materials Science and Microgravity science and technology. Director of the Physical Sciences Research Division in the Biological and Physical Enterprise at NASA headquarters Remote Sensing • So far, there are many RS departments in: ;VAST: Institute of Physics, Institute of Geology, Institute of Geography, Institute of Oceanography, etc. ;Ministry of Agriculture and Rural Development (MARD): Forest Inventory and Planning Institute (FIPI), National Institute of Agricultural Planning and Projection (NIAPP), etc. ;Ministry of Natural Resources and Environment (MONRE): Remote Sensing Center (RSC). Remote Sensing • The Ministry of Science and Technology (MOST) is requested to draft “ The Master Plan for application and development of remote sensing technology in Vietnam up to year 2010”. The draft of the Master Plan is submitted to the Government for approval. • The 26th Asian Conference on Remote Sensing ACRS2005 will be held in Hanoi on 7-11 November 2005 (http:// www.acrs2005.ac.vn). VINASAT project • Currently, Viet Nam spends about $8-10 million annually to transmit and receive signals via foreign –owned satellites. • The Vietnam Post and Telecommunication Corporation (VNPT) has leased transponder from ASIASAT-2 for VSAT network development. VINASAT Project • The Vietnam Television (VTV) leased transponder of Thailand’s Thaicom and Russia’s Intersputnik. • The Voice of Vietnam radio, Vietnam Aviation Department and Vietsopetro leased transponder of Indonesia’s Palapa satellite and of Intersputnik satellite. VINASAT Project • Vietnam’s growing economy required significant increases in demand for telecomunications. services.Viet Nam is currently in need of a medium – size satellite with 20-28 transponders. The satellite must ensure adequate coverage for the television, aviation, communications and petroleum sectors. The expected orbital slot for VINASAT is 1320 East. • Vietnam Post and Telecommunications Corporation (VNPT) has been assigned by the government of Vietnam to be an investor in this project. VINASAT Project • The “VINASAT project ” for launching the first Vietnamese communication satellite is initiated in 1995. • The pre-feasibility study of the VINASAT project is approved in 1998. • The National Steering Committee for VINASAT project headed by one Deputy Prime Minister has established on May 1999. VINASAT Project • The feasibility study of VINASAT is approved on the end of 2002. • The international bidding of VINASAT is carried out in July 2003. • But the first communication satellite of Viet Nam VINASAT won’t be launched in 2005 as planned. The delay comes amid Vietnam ‘s unfinished negotiations with partner nations regarding the satellite’s orbit position. Strategy for Research and applications of Space Technology up to 2020 • In June 2002, the Prime Minister asked VAST in collaboration with MOST and relevant ministries to elaborate the strategy. • After 3 years of discussion and revision, now the final draft of the strategy has submitted to the PM for approval in this quarter of 2005. Strategy for research and applications of Space Technology: main tasks/projects • VINASAT project (Ministry of Posts and Telematics). • Receiving ground station, satellite data centre (MONRE). • Small satellite project (VAST). • Space Technology Institute (VAST). • Viet Nam Space Commission (VAST). Strategy for research and applications of Space Technology: main tasks/projects • National Research Programme on Space Technology (MOST). • Space Technology specialists training (Ministry of Training and Education). “Natural Resources and Environment Monitoring System” Project • MONRE has submitted this project. The technical system of the project consists of: – Viet Nam ground station (VNGS); – National Data Center (NDC); – Data Utilization Systems (DUS). • The VNGS uses multi sensor receiving technology of EADS (European Aeronautic Defense and Space company). • The VNGS is located at Tu liem district (Hanoi) and will be operating from the end of year 2007 under the management of Remote Sensing Centre (RSC). Small satellite project • VAST has submitted to the PM a prefeasibility study of the project in 2001. But, this project was temporally stop until the “ Strategy for research and applications of Space Technology “ will be approved. • VAST proposes to participate a constellation of small satellites for monitoring disaster, if any, in the period (2006-2010). Establishment the Viet Nam Space Commission (VNSC) • VAST’s proposal: to establish Viet Nam Space Commission with the following tasks: – To co-ordinate all space activities implementing the projects or tasks of the Strategies. – To represent of Viet Nam in participating space activities and organizations. • Minister of Science and Technology will be the President of VNSC. President of VAST will be standing Deputy President of VNSC. The deputy ministers of ministries relevant are members of VNSC. Establishment the Space Technology Institute (STI) • STI will be establish as the 19th national institute of the Vietnamese Academy of Science and Technology. Conclusion To develop Space Technology, besides the mobilizing all internal resources, Viet Nam needs the experiences and technology from developed countries through bilateral or multilateral cooperation. Comment on the main theme of APRSAF-12 • Under the main theme entitled “ Maximizing Space Benefits for the Society “ , we agree to focus on the use of space technology to cope with environment problems, to prevent and to mitigate risks of disasters. • During the recent years, natural disasters occurred more frequent in the world, particularly in Asian region, including Viet Nam and caused serious aftermath. Here, we refer the tropical storm Damrey which cause a flash flood in Yen Bai province. Tropical Storm Damrey Track (26-27/9/2005) Do Son (Hai Phong) in Damrey tropical storm Thinh Long (Nam Dinh) in Damrey tropical storm Damrey damages Vietnam’s sea dyke Landslides cut off road section After the flash flood Tropical Storm Damrey • 69 people were killed and 28 injured by the storm and resulting floods and landslide that stuck the northern mountain provinces. • 4,746 houses were washed; 113,523 houses were submerged. • 77,841 m of sea and river dykes were damaged. • 318,945 ha of rice and subsidiary food crops were destroyed. • Loss are estimated at 3,5 trillion VND. • The co-operation had helped keep losses to a minimum. But the forecast flash floods was still inadequate. How to use space technology efficiently to forecast flash flood and landslide ? Mini Project 2004 – 2005 (sponsored by JAXA) Application of Satellite and GIS Data for change detection of Land-cover and Land –use in Coastal Zone of Vietnam Mini Project • The Space Technology Application Center- Institute of Physics and Electronics (VAST) in co-operation with the Geoinformatics Centre- Asian Institute of Technology is conducting this project. • Data used: MOS-MESSR 90 & 94, JERSOPS 94&97 , Landsat ETM 2001& 2002. • • The Multispectral Electronic Self-Scanning Radiometer (MESSR) is onboard the Marine Observation Satellite (MOS). The Optical Sensor(OPS) is onboard the Japanese Earth Resources Satellite (JERS).
