Engineers from the Moscow Aviation Institute have concluded a series of investigations focused on improving communication reliability with spacecraft operating in deep space.
These advancements are targeted towards interplanetary missions that employ electric propulsion systems, which have the potential to interfere with onboard communication systems.
A significant innovation developed in this research involves the application of blind signal separation techniques, such as independent component analysis. This methodology facilitates the isolation of the desired signal from emergent interference by analyzing their distinct statistical properties. This is particularly crucial for spacecraft operating at vast distances from Earth, where the quality of communication is paramount for accomplishing scientific and technical objectives.
The researchers have also introduced an novel strategy for employing relays. Instead of positioning them in fixed orbits, the proposal is to deploy escort craft equipped with electric propulsion systems onto personalized trajectories that are synchronized with the primary spacecraft’s flight path.
According to the researchers, this adjustment will enable the maintenance of more consistent communication throughout the entirety of the journey.
The outcomes of this study establish a new technological foundation for executing ambitious interplanetary initiatives and unlock enhanced possibilities for dependable communication over distances spanning hundreds of millions of kilometers. These findings have now been forwarded to pertinent enterprises within the rocket and space industry for subsequent practical development.
