Missile
Set the basic properties of a missile and propagate a ballistic flight path
Syntax
Missile <ObjectPath> Trajectory {TimeValue} <StepSize> {LaunchOption} <LaunchParameters> {TrajOption} <Value> {ImpactOption} <ImpactParameter>
Description
The Missile command sets the basic properties of the specified missile and propagates the flight path at the specified {TimeValue}.
For valid {TimeValue} values see Time Options.
<StepSize> is entered in Connect Time units.
To change Connect units use the SetUnits command. To see the current settings for Connect units use the ShowUnits command.
{LaunchOption} and <Parameters> can be:
| {LaunchOption} | <Parameters> | Description |
|---|---|---|
| LnLatGeoD | <GeodeticLatitude> <Longitude> <Altitude> | <GeodeticLatitude> and <Longitude> are entered in degrees. <Altitude> is entered in Connect Distance units. |
| LnLatGeoC | <GeocentricLatitude> <Longitude> <Radius> | <GeocentricLatitude> and <Longitude> are entered in degrees. <Radius> is entered in Connect Distance units and must be greater or equal to 0.0. |
{TrajOption} and <Parameters> can be:
| {TrajOption} | <Parameters> | Description |
|---|---|---|
| TOF | <FlightDuration> | <FlightDuration> is entered in Connect Time units and must be greater than 0.0. This value is the duration of the vehicle's flight. |
| DeltaV | <DeltaV> | <DeltaV> is entered in (Connect Distance units)/(Connect Time units) and must be greater or equal to 0.0 m/sec. If you enter 0, the minimum Delta-V is computed for launch and impact locations. This value is the instantaneous thrust, to be applied to the vehicle being launched. This option generally results in shallower trajectories and is a much better choice when launch/impact points are close or when they are both on one side of the descent/accent arc. |
| ApogeeAlt | <ApogeeAltitude> | <ApogeeAltitude> is entered in Connect Distance units and must be greater or equal to 0.0. This value is the vehicle's maximum altitude. |
| DeltaVMinEcc | <DeltaV> | <DeltaV> is entered in (Connect Distance units)/(Connect Time units) and must be greater or equal to 0.0 m/sec. This value is the instantaneous thrust, with minimum eccentricity, to be applied to the vehicle being launched. This option generally results in shallower trajectories and is a much better choice when launch/impact points are close or when they are both on one side of the descent/accent arc. |
{ImpactOption} and <Parameters> can be:
| {ImpactOption} | <Parameters> | Description |
|---|---|---|
| ImLatGeoD | <GeodeticLatitude> <Longitude> <Altitude> | <GeodeticLatitude> and <Longitude> are entered in degrees. <Altitude> is entered in Connect Distance units. |
| ImLatGeoC | <GeocentricLatitude> <Longitude> <Radius> | <GeocentricLatitude> and <Longitude> are entered in degrees. <Radius> is entered in Connect Distance units and must be greater or equal to 0.0. |
| LaunchAzEl | <Azimuth> <Elevation> | <Azimuth> and <Elevation> are entered in degrees. |
If {ImpactOption} is LaunchAzEl, {TrajOption} must be DeltaV.
Latitude and Elevation values must be between -90.0 and 90.0 degrees. Longitude and Azimuth values must be between -180.0 and 360.0 degrees.
Examples
To propagate the Test missile:
To propagate it using launch geocentric coordinates, trajectory coordinates for apogee altitude and geodetic coordinates for impact:
To propagate the msl10 missile beginning at the scenario analysis time period start:
