SetSGP4Prop
Set the routine for an SGP4 propagator
Syntax
SetSGP4Prop <SatObjectPath> {Routine}
Description
This command provides the ability for you to choose the implementation of the SGP4 propagator that STK will use.
{Routine} is an optional parameter that allows you to select the SGP4 routine used for propagating ephemeris. Valid values or {Routine} are:
| {Routine} | Description |
|---|---|
| SGP4 | Use the internal SGP4 routine implemented by STK. |
| Default | Use the propagator selected in the Edit Preferences panel. |
| <Name> | Use an installed SGP4 plugin routine.
Use an installed SGP4 plugin routine, e.g., AFSPC-SGP4_V8. STK provides an interface to the AFSPC SGP4 routine - contact customer support. |
If no {Routine} is specified, the internal SGP4 (Default) routine will be used.
In the past you may have used the {Propagator} parameter to choose the USGovMSGP4 routine. This is no longer necessary, as the implementation of the internal SGP4 routine and the UsGov routine have been made the same.
These parameters are case sensitive.
Different SGP4 implementations (other than the internal SGP4 routine implemented by STK) may or may not be available to you, depending on your STK install configuration. You can determine if different routines are available by creating a satellite, choosing the SGP4 propagator on the Orbit Properties Page, and noting whether a combobox appears on the panel listing names of routines.
