Orbital Case 06C: Cylinder Undergoing Plane Change Firing
Orbital scenario 6C tests a cylinder undergoing a 29,000 N force being applied in the negative body y-axis direction after t = 1,000 sec for 93 sec in a nearly circular orbit type.
Constants and Models
This scenario uses a cylinder body model, specified here. The MET atmosphere model defines atmospheric properties based on time, position, and solar effects specified here. The gravitational model used was an inverse-square gravitation field, specified here. The geodesy model used for this scenario is the WGS-84 rotating model, specified here.
