Spacecraft Object

Top  Previous  Next


The Spacecraft object is the heart of FreeFlyer. You can define the orbit and attitude states of a Spacecraft in a variety of element sets and reference frames, define physical attributes such as mass and drag area, add various subsystems, and control the motion model. See The Spacecraft Object Guide for more information. You can assign Spacecraft objects using the = operator. This will equalize the Spacecrafts' properties, but not the properties of any attached objects (such as Propagators, ForceModels, Tanks, Sensors, and Thrusters).
