Add further attitude profiles to a single object
AddAttitude <ObjectPath> Profile [<ProfileName>] {StartTime} {ProfileType} <Parameters>
Use the AddAttitude Profile command to add an additional profile for orienting a single vehicle. Profiles are ordered by {StartTime}. The optional <ProfileName> parameter allows you to specify the name of the attitude profile.
For valid {StartTime} values see Time Options.
Note: The command will nack if the start time entered is the duplicate of an existing profile's start time.
There will always be at least one attitude profile already existing for a vehicle. This attitude profile's start time will match the scenario start time. To change this profile use the AttitudeSegment Modify Profile command.
Hint: For further information on available {ProfileTypes} and <Parameters>, see the SetAttitude Profile Connect command.
In addition to the profiles described in the SetAttitude Profile Connect command, the FixedTimeSlew and VariableTimeSlew {ProfileTypes} are also available when adding attitude profiles to an existing vehicle.
<Parameters> for FixedTimeSlew {ProfileType} are described in the following table.
| FixedTimeSlew <Parameters> | Description |
|---|---|
| Smooth {On | Off} | Specify whether to take account of the angular velocity (slope) at the beginning and end of the slew. |
<Parameters> for VariableTimeSlew {ProfileType} are described in the following table. Any number of <Parameters> may be entered on one command.
| VariableTimeSlew <Parameters> | Description |
|---|---|
| Mode {FixedRate | Constrained} | Set the value for slew mode. The
default value is FixedRate.
If Constrained is entered the SlewType will be set to 2ndOrderSpline. |
| SlewSegmentTiming {Earliest | Latest | Optimal} | Specify when to execute the slew within the window of opportunity. The default value is Earliest. |
| SlewType {2ndOrderSpline | 3rdOrderSpline} | Set the type of the Constrained slew mode. This option will set the Mode to Constrained, if necessary. |
| RateMagnitude <Value> | Set the maximum slew rate. The <Value> must be between 0.0 deg/sec and 1000 deg/sec. The default value is 50 deg/sec. |
| RateAxisX {On | Off | <Value>} | Turn on or off, or set values for the
maximum slew rate axis constraints.
If the <Value> is entered the constraint will be also be turned On. Enter the <Value> in degrees/second. The <Value> must be between 0.0 deg/sec and 1000 deg/sec. The default value is for all RateAxis entries is 30 deg/sec. |
| RateAxisY {On | Off | <Value>} | |
| RateAxisZ {On | Off | <Value>} | |
| AccelMagnitude <Value> | Set the maximum slew acceleration. The
<Value> must be between 0.0 deg/sec^2 and 1000 deg/sec^2. The
default value is 5 deg/sec^2.
This option is used when slew Mode is Constrained. |
| AccelAxisX {On | Off | <Value>} | Turn on or off, or set values for the
maximum slew acceleration axis constraints.
If the <Value> is entered the constraint will be also be turned On. Enter the <Value> in degrees/second^2. The <Value> must be between 0.0 deg/sec^2 and 1000 deg/sec^2. The default value is for all RateAxis entries is 3 deg/sec^2 These constraints are used when slew Mode is Constrained. |
| AccelAxisY {On | Off | <Value>} | |
| AccelAxisZ {On | Off | <Value>} |
To Add a FixedTimeSlew profile to Satellite1:
AddAttitude */Satellite/Satellite1 Profile "1 Jun 2003 01:00:00.00" FixedTimeSlew Smooth On
To Add an InertFix profile, named MyInertial, to Satellite1:
AddAttitude */Satellite/Satellite1 Profile MyInertial "1 Jun 2003 02:00:00.00" InertFix Euler 10.0 20.0 30.0 321
If activated, Connect returns an acknowledgement message.
