Spacecraft.SetAttitudeMotionModel(String) Method

 Top 

Description

Sets the motion model to use for attitude propagation.

 

With a Kinematic model, the user can configure the Spacecraft attitude using Euler Angles, Quaternions, an Attitude Matrix, or by setting up a Spinner. When AHF is selected, the user can specify an ephemeris containing attitude data to use when propagating the Spacecraft.

Example 1

// Set up a Kinematic attitude using Euler Angles

Spacecraft1.SetAttitudeMotionModel("Kinematic");

 

Spacecraft1.AttitudeSystem = "EulerAngles";

Spacecraft1.AttitudeRefFrame = "LVLH";

Spacecraft1.EulerAngles[0] = 30;

Spacecraft1.EulerAngles[1] = 0;

Spacecraft1.EulerAngles[2] = 60;

 

 

// Set up an attitude using an AHF

Spacecraft1.SetAttitudeMotionModel("AHF");

Spacecraft1.AHF.LoadEphemeris("myAHFfile.ephem");
