Development of Precision Intelligent Systems of Autonomous Navigation and Attitude Control of Space Vehicles under Uncertainty Conditions: Mathematical Methods, Software and Modeling Means

Description

In the work the actual problems concerned to creation the reliable software for high-precision control systems of the modern and perspective spacecrafts (SC) on the basis of new achievements in control theory are developed. It is created constructive and flexible mathematical tools and methods of control including algorithms and software with using the advanced information technology which are realized in the specialized computer system (SCS). This SCS is destined for intellectual support of the problems that should be solved when control systems of the contemporary and perspective SC are designed that allow significantly to reduce the material and time expenses for their working out.

Innovative Aspect and Main Advantages

  • Accuracy increase of navigation and control systems by means of advanced algorithms of processing (filtration) of the information obtained from onboard measurement units;
  • Keeping of the working capacity of SC control systems with respect to separate failures in the measurement data;
  • Development of the methods for fault detection in measuring and executing tools and reconfiguration of the corresponding algorithms;
  • Increase of SC functioning autonomy during the Earth observations via the expansion of a spectrum of problems which should be solved by onboard control system including in particular the forming of angular movement reference control and switching programs for sensing equipments under the general information on the areas and shooting regimes which is set by the ground control station;
  • Development of the robust control algorithms which surely provide the stable solutions of SC attitude problems when essential difference of SC real dynamic properties from properties of the mathematical models used in control algorithms take place.

Areas of Application

Algorithms and software of precision reliable navigation and attitude control systems for promising multifunctional spacecrafts which are able to solve effectively a wide range of problems of investigation of Space and Solar system, as well as Earth monitoring. Complicated technological processes where reliable high-precision control is required.


Stage of Development

It is prepared the complex project of the new elaborations directed to creation of high-precision navigation and attitude control systems for various type of SC. Specialists and designers from Scientific and Production Enterprise HARTRON (leading firm of the former USSR which was involved in control systems development for srace-rocket technology including intercontinental ballistic missiles SS- 18, SS-19) are among project developers. In present the first part of the mathematical tools and modeling complex have been created and have been used for EgyptSat 1 navigation and attitude control system design. This satellite was manufactured by Ukraine for Egypt and which shows the successful operation results.
