The three vehicles were among five UAVs manufactured by the institute as part of a State scientific research project.
The successful test fights mean that the project's engineers andstaff have become the first Vietnamese people to successfully researchand build UAVs in Vietnam, said the project director Pham Ngoc Lang.
They will be used for scientific research servingsocio-economic development, such as the study of desertification, theimpact of climate change and deforestation in Tay Nguyen (CentralHighlands), Lang added.
The director confirmedthat the institute will now focus activities on expanding the flyingrange and technology of the vehicles in preparation for mass production.
Of the three tested UAVs, the smallest (1 metrelong and 1.2 metres wide) has an operation radius of 2 kilometres andcan reach a height of 200 metres and a speed of 70 kilometres per hour.
The second biggest (1.8 metres long and 2.7metres wide) can travel as far as 15 kilometres at speeds of up to 120kilometres per hour and heights of 3,000 metres. It can take off from a200-metre runway or a launching platform and it can land by runway orparachute. It is capable of sending data remotely.
The largest craft (2.6 metres long and 3.2 metres wide) can fly forthree hours at speeds of 150 kilometres per hour. All three are equippedwith high-resolution cameras.
The UAVs are all operated using an automatic control system following programmes set on a digital map foundation.
Former Minister of Post and Telecommunications Do Trung Ta said thatthe successful test of the UAVs was a milestone in Vietnam'sscientific research, especially in cybernetics and informationtechnology.-VNA
