DLR scientists demonstrate more efficient satellite communications technology

German Aerospace Center (DLR) satellite communication researchers have demonstration a new data compression technology for the first time. This demonstration was made possible using network coding, which reduces transmission bandwidth requirements. The process has applications, for example, in emergency response, when local networks fail and emergency services have to fall back on satellite communications. For internet and cellular traffic, data is transmitted over terrestrial links and network coding is used sometimes, but it is new for satellite communications.
