Detailed Description

A planet fixed object.

This models an object fixed to a planet. Allows any model to be a child and will work like rigid_body.

Member Function Documentation

Computation done during numerical integration.

Quaternion kinematics and orbit derivative.

Uses qi_to_b_dot from the SCControl framework.

dsim_value planet_fixed_object::handle_message	(	const std::string &	sender_path,
		const std::string &	message_name,
		const dsim_value &	argument
	)

Handle force and torque messages.

Handle the messages.

The units should be N and Nm. Force should be in the ECI frame and torque should be in the body frame.
