Models of non-gravitational accelerations, of which satellite aerodynamics and radiation pressure are the most important examples, are critical for many orbit determination and prediction applications. Such models typically consist of three parts, each of which can be implemented at various levels of sophistication, depending on the required accuracy of the application. The first part consists...

The residual atmospheric density present at orbital altitudes produces an aerodynamic disturbance, both to satellite orbits and attitude, that at Very Low Earth Orbits (<450 km) can be significant, usually being the strongest disturbance. Certain spacecraft shapes are considered to be aerostable as a restoring aerodynamic torque appears when the spacecraft aerodynamic equilibrium attitude -...

ESA's Space Environment Information System (SPENVIS) is an on-line resource for evaluating the space environment and its effects on spacecraft components and astronauts. The SPENVIS system provides access to a large number of space environment models and related analysis tools, allowing the users to combine and chain results between different models. SPENVIS has a long and acclaimed history....

Trajectory design and orbit maintenance are a challenging task when multi-body dynamics is involved or in the vicinity of a planet, where the effect of orbit perturbations is relevant. This is the case of many applications in Space Situation Awareness (SSA), for example in the design of disposal trajectories from Medium Earth Orbits, or Highly Elliptical Orbits or Libration Point Orbits, or in...

The AADDTool - Analysis of Attitude Disturbances and Dynamics Tool – was developed to analyse the disturbances impacts on the dynamics of the spacecraft, start tracker blinding, wheels momentum unloading schemes, and solar power supply, for long term missions in meteorological missions for EUMETSAT. The configuration and setup of the mission is supported by a dedicated graphical interface, for...

In this paper, we present the ESA Debris Environment Long Term Analysis (DELTA) tool, used to analyse the long term propagation and evolution of the future debris environment. DELTA is one of the models that contribute to the IADC studies on long term evolution, which have already been used to derive the mitigation guidelines and have also underlined the need for Active Debris Removal (ADR)....
