VNREDSat-1 Project’s highlightsIn the frame of the National Strategy for Research and

Applications of Space Technology towards 2020.Based on research, assessments on Vietnam’s practical needs,

as well as current technologies and trends in the world. Taking all the advantages of the existing infrastructure in

Vietnam including the Vietnam natural resources and environment monitoring system implemented by MONRE for the purposes of uniform administrative management and cost-effectiveness. An upgrade of the satellite image receiving station and joint operation procedures will be put in place.

Once completed, Vietnam will possess a complete and independent EO system including infrastructure, human resources and knowledge, that also supplies for the increasing needs of Vietnamese ministries, agencies, cities and provinces.

Launch serviceVNREDSat-1 satellite is compatible with many

launchers such as Soyuz, VEGA, PSLV, Rockot, Dnepr, …

Target of launch period: 2013 – 2014.Selection depends on:

Satellite mission and designMarketLauncher availabilityODA constraints

16

Launch insuranceCoverage period: from intentional ignition of

the launcher until end of In-Orbit tests. Based on System Performance Mark (PM)

Total loss: rebuild and re-launch of a replacement satellite

Partial loss: equivalent indemnity to be paid

17

Training and Technology transfer1. Long-term training:

Customer Trainee Team (CTT): 15 VAST members

Phase 1: Academic training (Basic and advanced)

Phase 2: On-the-job training, involves in satellite and ground segment development activities (in France and in Vietnam)

2. Short-term training: in small satellite technology, program management, remote sensing applications, …

Science and technologyA core engineers team is trained on satellite

technology, to archive independent capabilities in space for Vietnam .

Guidelines for other hi-tech industries in Vietnam such as electronics, telecommunication, IT, material science, robotics as well as other basic research fields such as mathematics, mechanics and physics, etc.

Satellite images are key inputs for research in ecology, geography, geology, hydrology, marine and environment. The research quality will be remarkably improved by maximizing utilization of satellite images.

VNREDSat-1 project benefits

21

Socio-economy:Active daily monitoring of natural disasters for timely

response and rescue activities to minimize losses in properties and human lives.

Provision of high-resolution satellite images for land-use mapping, inventory, investigation and planning in forestry, agriculture, aquaculture; urban planning, ...

Topographical map regular correction, annual update. Mineral resources research. Water resource and environmental change monitoring,

e.g. unknown sources of oil spill in 2007 due to lack of timely satellite images.

Off-shore fishing applications.

Conclusion

22

VNREDSat-1 satellite system, the 1st EO system of Vietnam, will supply for the increasing need of remote sensing images in Vietnam, for both scientific and economic objectives.

The success of the VNREDSat-1 project will put Vietnam in a higher position amongst the countries possessing their own EO satellite systems.

VAST, as the project owner, has entrusted EADS Astrium – an European leading satellite manufacturer – to develop its 1st earth-observation satellite and to aim for the long-term cooperation in space technology.
