Description
The LinearTangentSteering object provides a collection of properties and methods associated with the linear tangent thrust steering method. This object is always created as a child object of the FiniteBurn object, as seen in the example below:
FiniteBurn1.LinearTangentSteering.LamdaDot = {0, 0, 0};

Type: String
Access: Read-Only
|
DisplayName
|
The name displayed for this object in output windows such as views, plots, and reports.
|
Type: String
Access: Read/Write
|
LambdaDot
|
The lambda dot value used for steering the thrust direction based on the Linear Tangent Steering law. No unitization is performed on this value by FreeFlyer. The user is responsible for determining the burn model constants, which specifies the burn direction over time.

LambdaRef
|
The lambda reference value used for steering the thrust direction based on the Linear Tangent Steering law. No unitization is performed on this value by FreeFlyer. The user is responsible for determining the burn model constants, which specifies the burn direction over time.

|
PutToFile
|
Convert the object state to FreeFlyer object xml and write to a file.
|
PutToString
|
Convert the object state to FreeFlyer object xml and return as a string.

Restore
|
Restore an object's state from a previously saved state.
|
Save
|
Save the object's state so that it can be restored later.
|
SetReferenceTime
|
Set the reference time for the Linear Tangent Steering algorithm. This value is set as an epoch in MJD TAI.
|
SetReferenceTimePercentage
|
