Computational methods in the monitoring of satellite AOCS

During the last decades modeling, simulation, and wider computational science and engineering have become more and more important tools in the research and development. The design phase has to be reduced in time and cost when the use of new ideas and tools becomes possible. This is also the trend in space application in which the real tests are not possible or at least they are very expensive. New demands on the aerospace and control engineering have become up and they have to be able to answer to requirements.

The aim of the LAMA project is to:

  • design and implement a generic simulation model of satellite attitude and orbit dynamics with suitable failures and perturbations;
  • research, how the implementation of attitude and orbit control system (AOCS) can be make more efficient;
  • research, how the model based tools can be utilized in the design, implementation and validation of AOCS software;
  • research, develop and test new ideas in FDI.

One of the main aims is to develop a generic attitude and orbit dynamics satellite simulation model in which the most common actuators and sensor failures, and environmental perturbations such as aerodynamics drag, gravity field granularity and the Earth oblateness have been taken into account.

Space Systems Finland is our key industrial partner and TEKES, the National Technology Agency of Finland, is our main financer.

This project is part of TILLIKKA.
