Detailed Description

Rigid body dynamical model applying force and body rae to the spacecraft.

Integrates the position, velocity and quaternion. Body rates are an input. Children can use the apply_force messages.

Member Function Documentation

void rigid_body_no_rate_dynamics::rhs	(	double	t,
		double	jd
	)

Computation done during numerical integration.

Quaternion kinematics and orbit derivative.

Uses qi_to_b_dot from the SCControl framework.

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

Handle force and torque messages.

Handle the apply_force and apply_torque messages.

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

References force.
