After the success of the previous editions in Logroño (2014) and Toulouse (2015), the next KePASSA edition will take place in July 25-27,  2017, and will be hosted by ESTEC.

The workshop is concerned with the following TOPICS AND METHODS:

  • Analytical and semi-analytical methods for long- and short-term propagation.

  • High Earth Orbit and High Elliptical Orbit.

  • Third body and time dependence in the analytical method.

  • Resonances and chaos.

  • Propagation of orbit uncertainties and orbit determination

  • Regularized numerical integration.

  • Lagrange planetary equations.

  • Hamilton canonical equations.

  • Special functions.

  • Series expansions.

  • Symbolic integration with software tools.

  • Time series.

  • Hybrid and statistical methods.

  • Software packages for orbit propagation.
