Package org.orekit.attitudes Description

This package provides classes to represent simple attitudes.

Some force models such as the atmospheric drag or the maneuvers need to know the spacecraft orientation in inertial frame. OREKIT uses a simple container for Attitude which includes both the geometric part (i.e. rotation) and the kinematic part (i.e. the instant spin axis). The components hold by this container allow to convert vectors from inertial frame to spacecraft frame along with their derivatives. This container is similar in spirit to the various extensions of the abstract Orbit class: it represents a state at a specific instant.

In order to represent attitude evolution in time, the AttitudeLaw interface is available. Several classical attitude laws are already provided in this package.
