Methods

 

Name

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.
