Spacecraft parameters.

Overview#

Properties

`dry_mass`	Get or set the mass of the spacecraft exclusive of propellant. Uses Mass Dimension.
`cd`	Get or set the dimensionless drag coefficient associated with the drag area. Dimensionless.
`drag_area`	Get or set the cross-sectional area of the spacecraft assumed perpendicular to the direction of motion, used for atmospheric drag calculations. Uses SmallArea Dimension.
`cr`	Get or set the reflectivity of the spacecraft used for solar radiation pressure calculations, where 2.0 is fully reflective and 1.0 is not reflective at all. Dimensionless.
`solar_radiation_pressure_area`	Get or set the cross-sectional area of the spacecraft assumed perpendicular to the direction of solar radiation, used for solar radiation calculations. Uses SmallArea Dimension.
`ck`	Get or set the reflectivity of the spacecraft used for central body radiation pressure (albedo / thermal pressure) calculations, where 2.0 is fully reflective and 1.0 is not reflective at all. Dimensionless.
`radiation_pressure_area`	Get or set the cross-sectional area of the spacecraft assumed perpendicular to the direction of central body radiation, used for central body radiation (albedo / thermal pressure) calculations. Uses SmallArea Dimension.
`k1`	If you are using a non-spherical SRP model, this field defines the model’s GPS solar radiation pressure K1 (scale) value. Dimensionless.
`k2`	If you are using a non-spherical SRP model, this field defines the model’s GPS solar radiation pressure K2 (scale) value. Dimensionless.
