Japanese satellites will broadcast Morse code with led lights

A small Japanese satellite, which has just been released into space with Vietnam's F-1 satellite, will generate Morse codes with led light, visible throughout the world.

Morse code is a type of character encoding used to transmit telegraph information, including a standardized string of long and short elements to represent letters, numbers, dots, special characters of a message.

Long and short words may be represented by sounds, marks or tiles, or pulses, or symbols commonly referred to as "dots" and "tiles" or "dot" and "dash" in English. .

The researchers hope that a 10-centimeter-sized satellite dropped into space from the International Space Station (ISS) by the robotic arm, will become the first orbiting satellite to deliver a signal on the LED. night sky, AFP said.

Professor Takashi Tanaka of Fukuoka University, the head of Japan's manufacturing group of satellites, said the message was originally intended to be seen only in the Japanese sky, but many people in countries like Germany , Italy, Brazil, England, Hungary, America have asked to see these codes.

Observers can use binoculars to detect light trails in the sky. The northern hemisphere will see a green light trail, because of the front view of the satellite. People in the southern hemisphere will see red light, because observing the back of the satellite.

Takashi Tanaka also said that the purpose of bringing satellites to space to see how much time it takes for light from the LED to reach Earth while the images will be transferred at 115 kilobits per second.
