High-speed X-band radio link

Problem to be solved: Low data transfer rate from spacecraft to land and sea objects with limited communication session time (small number of receiving stations or impossibility of their uniform installation throughout the entire territory of the Earth) and unstable weather conditions. Tasks to be solved: Increasing the efficiency of data transfer from spacecraft for remote sensing of the Earth (ERS). Potential increase in the productivity of ERS spacecraft. Development of a prototype of a technical system for high-speed transmission for spacecraft operating in the X-band. Proposed solution: Creation of an adaptive high-speed transmission system for a spacecraft operating in the X radio band. Because the system has wide-angle electronic scanning, an adaptive preliminary digital distortion system and a frequency equalizer, we can increase the capacity of the radio channel for data transmission (up to 1500 Mbit/s in the prototype, potentially up to 2200 Mbit/s). In addition, we can ensure stable communication when weather conditions and the spacecraft angle of observation change, while maintaining small dimensions and low consumption of the data transmission system on board the spacecraft.
