Attributes
|
AttachedSensors
|
An array of Sensor objects attached to the Transponder to act as antennas for measurement modeling purposes. The Sensor's X, Y, and Z position properties will be used to model an offset from the origin of the Spacecraft BCS when modeling measurements.

Description
|
Attach
|
Attach a Sensor object to the calling hardware object for the purposes of simulating tracking data or performing Orbit Determination. The Sensor's X, Y, and Z position properties will be used to model an offset from the origin of the Spacecraft BCS when modeling measurements.
|
ClearSavedStates
|
Clears previous saved states for this object.
|
Detach
|
Detach a Sensor object from the calling hardware object.
|
GetFromFile
|
Load the object state from the specified FreeFlyer object file.
|
GetFromString
|
Load the object state from the specified string.
|
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.
|
ReferenceEquals
|
Returns 1 if the argument refers to the calling object and 0 otherwise.
|
Restore
|
Restore an object's state from a previously saved state.
|
Save
|
Save the object's state so that it can be restored later.
