Launched today, the world's first fully reprogrammable commercial satellite is ushering in a new age of flexible communications.The UK-engineered Eutelsat Quantum, unlike conventional models, can be modified almost immediately.Friday's launch of the satellite from French Guiana was made by an Ariane 5 rocket.The European Space Agency claims that the Quantum can be programmed from its fixed orbit 35,000km (22,000 mi) above the Earth. This allows it to respond to changing data transmission requirements and secure communications over its 15-year lifespan.Eight communication beams are included in the Quantum model, which weighs in at 3.5 tonnes. Each beam can be adjusted to adjust its coverage area and the strength of the signal it emits.These changes can be made using software provided to customers, and are possible in just minutes according to Eutelsat.The satellite can also be used to provide mobile coverage of moving objects, such as planes and oceangoing vessels, coverage after natural disasters or for one-off events.Quantum can pinpoint the source of signals that are emitted with malicious intent or not, and take appropriate action to correct any interference. This comes at a time when digital security is becoming increasingly important.The Quantum will be able to cover large areas from West Africa to Asia.
