The RCC told about a new method that suppresses unnecessary signals
The method developed at the Research Institute of Precision Instruments (part of the Russian Space Systems) will help improve the accuracy and reliability of docking spacecraft with the International Space Station.
It’s no secret that spacecraft automation sometimes “refuses” to accurately “catch” the station, and astronauts have to switch to manual control. In particular, such an incident occurred in October 2021 during the approach to the ISS of the Soyuz MS-19 spacecraft with the film crew of the film The Challenge. The only cosmonaut on board, Anton Shkaplerov, had to dock manually, which was associated with a certain amount of risk.
One of the reasons for such difficulties in orbit is the peculiarity of the operation of the Kurs docking system. It consists in the abundance of re-reflections of signals from elements of various structures. Due to the complex configuration of the ISS, which consists of various modules, batteries, trusses, the measured parameters are often distorted, and this leads to the loss of the “docking” contact between the spacecraft and the station.
The new method, developed at the Research Institute of Technology, will help to significantly suppress re-reflected signals and thereby improve the accuracy of the measurements. This was done due to more advanced digital processing of the totality of received data.
