Description
The BRTSUTDFFile object provides functionalities for reading Bilateration Ranging Transponder System (BRTS) Observation data (two-way Doppler and two-way range) from binary files written in the 75-byte binary Universal Tracking Data Format (UTDF). The time system for data contained in the BRTSUDTFFile is UTC, TwoWayRange data are given in km, and TwoWayDoppler data are given in Hz.

Determines whether to set the Validity flag on measurements as they are loaded, based on the applicable limits for the particular measurement type.
|
BRTSLinks
|
An array of the observing GroundStations.
|
DataSpanEndEpoch
|
The Epoch of the last Observation in the file.
|
DataSpanStartEpoch
|
The Epoch of the first Observation in the file.
|
DeclaredName
|
The name of the object as declared.
|
DisplayName
|
The name displayed for this object in output windows such as views, plots, and reports.
|
Filename
|
The file name to load.
|
FirstObservation
|
The first Observation in the file.
|
LastObservation
|
The last Observation in the file.
|
NoObservationErrorAction
|
Specifies the behavior when no matching observations are found in the TrackingDataFile.
|
ObjectBeingObserved
|
The TDRSTransponder object attached to the Spacecraft that is being observed.
|
ObjectId
|

|
GetFromFile
|
Load the object state from the specified FreeFlyer object file.
|
GetFromString
|
Load the object state from the specified string.
|
GetNextObservation
|
Retrieves the next observation in file.
|
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.
|
ResetToStart
|
Resets the TrackingDataFile to the start of the file.
|
Restore
|

|
Save
|
Save the object's state so that it can be restored later.
|
SetObservedTransponder
|
Set the Transponder of the Observed Spacecraft for the tracking data in the file.
