Le Thanh Dat, student of Ho Chi Minh City  University of Technology, has devised an innovative automatically navigation antenna system for better reception of TV signals in difficult terrains.

The reception of TV signals with fixed antennas on such means of transport as trains, long-distance coaches, especially on boats at sea is always interrupted by the constantly changing positions.

To overcome this drawback, Dat, a major in electronics and electrical engineering, spent three years doing extensive research and built the antenna system with the guidance from Associate Professor, Dr. Hoang Dinh Chien.

This system consists of a compact control box, a keyboard and a small LCD screen to enter and display access parameters as well as a swiveling antenna directly connected to the TV.

To always obtain the best signals, users simply enter the coordinates of the transmitting stations. Upon reception of the necessary data, the device will automatically process them, and the antenna will always rotate toward the TV stations.

As a result, even if the vehicles or boats move through different areas, or TV channels are switched, the antenna will automatically rotate in the direction of the TV stations to ensure smooth signals and good image quality.

Dat has repeatedly tested his system by connecting the antenna to the TV set and continually changing the positions of the transmitters to check the quality of the received images. The results have been very encouraging.

According to his professor, Dat’s automatic navigation antenna system is his thesis to complete the affiliate engineering course between a French university and HCMC University of Technology. His thesis is highly acclaimed by both the French and Vietnamese juries and landed him a scholarship to study in South Korea.

Locals, particularly fishermen enthusiastically welcome Dat’s invention.

“When at sea, we mostly receive information, especially about the weather, via Icom. If we can watch TV with good quality, it’s really a great channel of entertainment and information,” said Bui Van Lien, a fisherman in central Quang Ngai province’s Ly Son island district.
