PhysicalProperties

Physical properties of satellite object

Since R2024a

Description

PhysicalProperties adds, retrieves or modifies satellite scenario numerical orbit propagator options.

Creation

You can create PhysicalProperties objects using the physicalProperties function of satellite object.

Properties

Mass — Satellite mass

4 (default) | positive scalar | positive vector

Satellite mass in kg, specified as a positive scalar or vector. When specified as a scalar, the value is applied to all satellites in sat. When specified as a vector, the number of elements in 'Mass' should be equal to that of sat. Each value in 'Mass' is applied to the corresponding element in sat.

DragCoefficient — Satellite drag coefficient

2.179 (default) | positive scalar | positive vector

Satellite drag coefficient, specified as a nonnegative scalar or vector. When specified as a scalar, the value is applied to all satellites in sat. When specified as a vector, the number of elements in 'DragCoeffiecient' should be equal to that of sat. Each value in 'DragCoefficient' is applied to the corresponding element in sat.

DragArea — Satellite drag area

1 (default) | positive scalar | positive vector

Satellite drag area in m², specified as a nonnegative scalar or vector. When specified as a scalar, the value is applied to all satellites in sat. When specified as a vector, the number of elements in 'DragArea' should be equal to that of sat. Each value in 'DragArea' is applied to the corresponding element in sat.

ReflectivityCoefficient — Reflectivity coefficient of the satellite

1.8 (default) | positive scalar | positive vector

Reflectivity coefficient of the satellite, specified as a nonnegative scalar double. When specified as a scalar, the value is applied to all satellites in sat. When specified as a vector, the number of elements in 'ReflectivityCoefficient' should be equal to that of sat. Each value in 'ReflectivityCoefficient' is applied to the corresponding element in sat.

SRPArea — Solar radiation pressure area

1 (default) | nonnegative scalar | nonnegative vector

Solar radiation pressure area in m², specified as a nonnegative scalar or vector. When specified as a scalar, the value is applied to all satellites in sat. When specified as a vector, the number of elements in 'SRPArea' should be equal to that of sat. Each value in 'SRPArea' is applied to the corresponding element in sat.
