RUDN scientists have found out how to reduce the cost of flights to satellites
1200 spacecraft rotate in different orbits around the Earth. However, the period of their active existence is limited due to the short-lived on-board equipment, malfunctions and the inevitable fuel consumption. Classic maintenance schemes, when the service device is launched from the Ground, lead to huge costs. Such schemes are justified if the satellite is in orbit in a single copy and is of high value (for example, the Hubble telescope).
A team of RUDN scientists has found the best solution for servicing low-orbit groups that consist of dozens of satellites — it minimizes fuel consumption due to optimal maneuvering. Using the algorithm on board the service module will allow you to quickly and with high accuracy estimate the trajectory of the flight to the satellites for a limited time, taking into account the fuel supply on board the module.
"One of the primary tasks when creating promising space systems, along with technical implementation and solving legal issues, is the choice of the orbital construction of the system, the calculation of flight trajectories... We have created a number of high-speed algorithms and a software and mathematical apparatus for selecting the orbits of the space service system and analyzing its functioning according to various optimization criteria. Our algorithm is also applicable for assessing dangerous approaches to other satellites and space debris objects," Vladimir Razumny, Ph.D., Associate Professor of the Department of Mechanics and Mechatronics, Academy of Engineering, RUDN University.
Matilda Pavlovna Mityaeva was born in 1925. In November 1942, she volunteered for frontline duty. She participated in the Great Patriotic War from November 1942 to June 1945 as part of the 53rd Infantry Division of the 475th Infantry Regiment. She was wounded twice.
The team led by Sergey Zyryanov, Head of the Department of General and Clinical Pharmacology, became the winner of the All-Russian competition of scientific projects "Technologies for Human Health".
RUDN University constantly adapts to the changes of the modern world and responds to challenges flexibly. This allows us to keep the standard of a world-class research university. The sphere of science is no exception. Peter Dokukin, Head of the Research Division, presented the updated R&D Programme at the meeting of the RUDN University Academic Council.
