Russian engineers will use an algorithm that will allow the information transmitted by spacecraft to be archived in orbit, significantly reducing the file size.
MOSCOW, February 2. /tass/. The new data compression algorithm created by the Russian Space Systems Holding (RKS, part of the Roscosmos State Corporation) will allow 10 times to increase data transmission from satellites. This was reported on Wednesday in Roscosmos.
"The technology being created in the RCS will allow to increase the volume of transmitted information from 1.2 to 10 times without changing the design of remote sensing spacecraft [remote sensing of the Earth]," the message says.
According to Roscosmos, Russian engineers will use a special adaptive mathematical algorithm that will allow archiving information transmitted by spacecraft directly in orbit, significantly reducing the size of the transmitted file.
"Such an algorithm can be implemented on remote sensing spacecraft, including those transmitting large amounts of data to Earth, such as Resurs, Condor, since the most promising technology is the compression of optical images, which occupy the largest amount of transmitted information and can be compressed without loss," Alexander Mordvinov, head of the digital-analog equipment development department of the RKS, is quoted in the state corporation as saying.
As stated in the message, it is almost impossible to achieve an increase in performance by conventional methods, since modern high-speed radio lines have almost reached the so-called Shannon limit (limits on the maximum data transmission rate through a channel with a given level of interference).
