LOP Drag (Satellites)

Set the LOP Drag parameters for a Satellite using the LOP propagator.

Syntax

LOP <SatObjectPath> Drag {DragOption} <Parameters>

Description

The LOP Drag command enables you to set the LOP drag parameters for a satellite using the LOP propagator by specifying a {DragOption} and necessary parameters.

{DragOption} can be:

{DragOption}<Parameters>Description
Basic{On | Off} <Cd> <CrossSectionArea>

<Cd> is the atmospheric drag coefficient and is between -10.0 and 10.0.

<CrossSectionArea> is entered in m**2 and is between 1e-5 and 99999.9 m**2.

Model{1976Standard | Exponential} [<RefDensity> <RefHeight> <ScaleHeight>]If 1976Standard is entered no other parameters should be entered.

If Exponential is entered, then also enter <RefDensity>, <RefHeight>, and <ScaleHeight>.

<RefDensity> is a number between 0.0 and 1000.0.

<RefHeight> and <ScaleHeight> are entered in Connect distance units and can be between 0.0 and 100000000.0 meters.

Advanced{OscAltState} <MaxDragAlt> <DensityWeightFactor>Valid values for {OscAltState} are On or Off.

<MaxDragAlt> is entered in Connect distance units and can be between 0.0 and 100000000.0 meters.

<DensityWeightFactor> can be between 0.0 and 1000.0.
