Description
The SetState TLE command sets the orbit state of the specified satellite, using the input two-line element set, and propagates the orbit. When specifying the TLE Cards, use the entire card, including spaces, and enclose each card in double quotes.
Each TLE Card must be 69 characters long. Do not leave out any spaces.
You can include the following {Options} on the command line:
| {Options} | Description |
|---|---|
| TimePeriod {TimeInterval} | Enter the span of the ephemeris. If not entered, then STK obtains the time period from the TLE card.
For valid {TimeInterval} values see Time Options. |
| TimeStep <StepSize> | Enter the interval between calculated ephemeris output points, in seconds. |
| Routine {SGP4 | Default | <Name>} | Specify the implementation of the SGP4 propagator to be used, where SGP4 is the internal SGP4 routine implemented by STK, Default is the propagator selected in the Edit Preferences panel, and <Name> is an installed SGP4 plugin routine, e.g. ASTROSTDS_SGP4_V9.
Astro Standards routines may be available as an option if you properly configured STK to support it. It is only available if you have obtained the official SGP4 DLL (and related files) from USSF (US Space Force) and performed a minor install procedure. STK provides an interface to the USSF SGP4 routines; contact customer support for more information. |
| NoProp | If you include this on the command line, STK will set the satellite's state but will not propagate it. |
Examples
Set Satellite1 to use the specified two-line element set:
Set Satellite2 to use the specified two-line element set, and propagate over the input time period:
