Diagram of comms satellites linked by lasers
Numéro d’image : 11889096
| Laser satellite communication. Artwork of the 'laser bridge' concept for linking communications satellites in orbit. At present (1995),long- distance communication is achieved by bouncing signals back and forth between Earth and a number of satellites. The 'laser bridge' idea is to send the message up to one satellite,then by infared laser beam along a chain of others. The signal is not sent back to Earth until it can go straight to the recipient. The laser system will allow a hundredfold increase in data transfer rates. And transfer will be secure since the laser signals are almost impossible to intercept. A military version of the system will go on trial from 1997 | |
