RUDN scientists have developed a new method for determining the orientation of objects in the antenna complex based on measurements of a strapdown inertial system
It is established that modern methods for determining orientation using measurements of satellite navigation systems or inertial orientation systems do not provide the required accuracy for solving the problem of orientation of large or medium-sized objects. In this regard, a new dynamic algorithm for estimating stochastic orientation parameters has been developed that is invariant to the nature of the base movement and provides stability and the required accuracy of estimation under the most General assumptions about the nature of interference of sensitive elements of a strapdown inertial orientation system built on the basis of WSG. The Rodriguez-Hamilton parameter vector is used as the observed vector of orientation parameters, and the accelerometer output signal is proposed to be used as its observer. Based on the stochastic nonlinear equations of the vector of parameters of the current orientation and the equations of stochastic models of accelerometer output signals constructed for the most General case of object motion, a generalized Kalman filter was formed that provides a General solution to the problem of estimating the orientation parameters of an arbitrary structure on a movable base. The results of numerical simulation confirmed the possibility of using the developed method for solving the problem of high-precision orientation determination without correction from global satellite navigation systems over a long time interval.

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.
