Spacecraft Orientation

The feature is designed be combined with a feature to define the spacecraft positioning. Multiple features can be defined. They are then available in the features.

The spacecraft positioning is set so that it faces exactly the primary pointing direction, and is rotated such that the secondary spacecraft pointing direction points towards the projection of the second orientation direction onto the plane normal to the primary axis.

Select one of the following option to define the :

•

(default) to make the primary spacecraft direction pointing toward the center of the planet, the opposite of Zenith.

•

to make the primary spacecraft direction pointing away from the center of the planet.

•

or to make the primary spacecraft direction pointing towards the Sun or to the opposite direction.

•

or to make the primary spacecraft direction pointing towards the direction of motion of the spacecraft or to the opposite direction.

•

or to make the primary spacecraft direction pointing towards the normal of the orbital plane or to the opposite direction.

•

to make the primary spacecraft direction pointing towards a point by giving its celestial coordinates. Set the and to locate the point with its celestial coordinates.

•

to define explicitly the pointing direction.

The and the directions should not be collinear.


	See Theory for Orbital Thermal Loads for the definition of the spacecraft position over time and the coordinate system transformation.
