Overview#
|
Drag Coefficient (Cd) - the dimensionless drag coefficient associated with the drag area. |
|
Solar Radiation Pressure (Spherical) Coefficient (Cr) - 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. |
|
Drag Area - the cross-sectional area of the spacecraft assumed perpendicular to the direction of motion, used for atmospheric drag calculations. Enter a value in the selected distance unit squared. |
|
Dry Mass - the mass of the spacecraft exclusive of propellant. Enter a value in the selected mass unit (e.g. kg). |
|
Fuel Density - the density of the fuel tank. Enter a value in the selected mass unit per the selected distance unit cubed (e.g. kg/m^3). |
|
Fuel Mass - the mass of the spacecraft propellant. Enter a value in the selected mass unit (e.g. kg). |
|
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. Enter a value in the selected distance unit squared. |
|
Radiation Pressure (Albedo/Thermal) Coefficient (Ck) - 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. |
|
Solar Radiation Pressure (Spherical) Area - the cross-sectional area of the spacecraft assumed perpendicular to the direction of solar radiation, used for solar radiation calculations. Enter a value in the selected distance unit squared. |
|
Tank Pressure - the fuel tank pressure. Enter a value in the selected pressure unit (e.g. Pa). |
|
Tank Temperature - the temperature of the fuel tank. Enter a value in the selected temperature unit. |
