Overview#

FUEL_MASS

Fuel Mass - the mass of the spacecraft propellant. Enter a value in the selected mass unit (e.g. kg).

CD

Drag Coefficient (Cd) - the dimensionless drag coefficient associated with the drag area.

CR

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

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

Dry Mass - the mass of the spacecraft exclusive of propellant. Enter a value in the selected mass unit (e.g. kg).

FUEL_DENSITY

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).

K1

GPS Solar Radiation Pressure K1 - if you are using a non-spherical SRP model, this field defines the model’s K1 (scale) value.

K2

GPS Solar Radiation Pressure K2 - if you are using a non-spherical SRP model, this field defines the model’s K2 (Y bias) value.

RADIATION_PRESSURE_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. Enter a value in the selected distance unit squared.

CK

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.

SRP_AREA

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

Tank Pressure - the fuel tank pressure. Enter a value in the selected pressure unit (e.g. Pa).

TANK_TEMPERATURE

Tank Temperature - the temperature of the fuel tank. Enter a value in the selected temperature unit.

MAX_FUEL_MASS

Maximum Fuel Mass - the maximum fuel mass of the spacecraft; this parameter specifically applies to Finite Maneuver segments that are being executed in Backward Sequences. Enter a value in the selected mass unit (e.g. kg).

TANK_VOLUME

Tank Volume - the volume of the fuel tank. Enter a value in the selected distance unit cubed (e.g. m^3). The minimum value is 1e-019 m^3.

X_OFFSET

X Offset - the distance that the spacecraft will be offset from the leader’s body frame along the X axis.

Y_OFFSET

Y Offset - the distance that the spacecraft will be offset from the leader’s body frame along the Y axis.

Z_OFFSET

Z Offset - the distance that the spacecraft will be offset from the leader’s body frame along the Z axis.
