Set the orbit state of a satellite from an SPICE file.
SetState <SatObjectPath> SPICE <Options>
The SetState SPICE command sets the orbit state definition of the satellite using a .bsp file. These are binary files that are in a standard format produced by the Jet Propulsion Laboratory (JPL). They are intended for ephemeris for celestial bodies but can be used for spacecraft.
Note: For a new SPICE satellite the File and BodyID must be specified.
At least one option must be entered on the command line. Valid <Options> are:
| <Options> | Description |
|---|---|
| File "<Filename>" | Enter an SPICE file to be added. This option is required for a new SPICE satellite. |
| BodyID <Value> | Enter the satellite ID value. This option is required for new Spice satellite or if specifying a new File and the BodyID is not in new File. |
| TimePeriod {TimeInterval} |
Enter {TimeInterval} to define the beginning and end of the satellite's time period for propagation. The interval must be within the file times; if not entered file times will be used. For valid {TimeInterval} values see Time Options. |
| TimeStep <StepSize> | Specify the interval between calculated ephemeris output points. Entered in seconds and must be greater or equal to 0.001 seconds. The default value is 60 seconds. |
| SegmentNumber <Value> | Specify the current segment. The default value is 1. |
| NoProp | If included on the command line the satellite's state will be set but it will not be propagated. |
Set the state for a new satellite using the SPICE propagator:
SetState */Satellite/Satellite1 SPICE File "C:\Users\Documents\ExternalFiles\SPICE\TestSat.bsp" BodyID 6556 SegmentNumber 1
Set the time step for the satellite, but don't propagate:
SetState */Satellite/Satellite1 SPICE TimeStep 120.0 NoProp
If activated, Connect returns an acknowledgement message.
