It was been while, number of searches, efforts, trials and errors past, aiming, to create the controller in Unity3D, which will allow orient a satellite toward target reference, i.e. an orbit of the planet. Rather than using standard Unity3D method Lerp, to set the orientation, I wanted to simulate close to realistic behavior, of thruster based controller for spacecrafts. This means, each individual axis of the satellite (spacecraft), can be controlled individually, to ensure desired orientation of 3 axis. Not only orientation can be defined for each 3 axis, but also angular velocity for any of axis. This allows for example, for traveling satellite, to spin around one of its axis, while pointing into desired direction.


The project was made using Unity 3D 2018.2.0b4. However, since is c# based, it should be able work on older version of Unity3D.

In case it do not work for any reaospn, specially for older version, copy of project folder is here:

Project uses Evolving Neural Network - NEAT, based on Evolving Neural Networks through Augmenting Topologies.
