Parameters
- ParameterName
Member Value Description eVAUpdateParamDragArea 0 Drag Area - the cross-sectional area of the spacecraft assumed perpendicular to the direction of motion, used for atmospheric drag calculations. eVAUpdateParamSRPArea 1 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. eVAUpdateParamDryMass 2 Dry Mass - the mass of the spacecraft exclusive of propellant. eVAUpdateParamFuelMass 3 The mass of the spacecraft propellant. eVAUpdateParamFuelDensity 4 The density of the fuel tank. eVAUpdateParamTankPressure 5 The fuel tank pressure. eVAUpdateParamTankTemp 6 The temperature of the fuel tank. eVAUpdateParamCr 7 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. eVAUpdateParamCd 8 Drag Coefficient (Cd) - the dimensionless drag coefficient associated with the drag area. eVAUpdateParamCk 9 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. eVAUpdateParamRadiationPressureArea 10 Radiation Pressure (Albedo/Thermal) Area - 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. - ActionType
Member Value Description eVAUpdateActionNoChange 0 No change in value - leave the current value for this parameter unchanged (ignoring any quantity that may appear in the Value column). eVAUpdateActionAddValue 1 Add value - add the quantity entered in the Value column to the current value for this parameter. eVAUpdateActionSubtractValue 2 Subtract value - subtract the quantity entered in the Value column from the current value for this parameter. eVAUpdateActionSetToNewValue 3 Set to new value - replace the current value for this parameter with the quantity entered in the Value column.
