Class TDMFile

java.lang.Object

org.orekit.files.ccsds.TDMFile

public class TDMFile
extends Object

This class stocks all the information of the CCSDS Tracking Data Message file parsed by TDMParser or TDMXMLParser.

It contains the header and a list of Observations Blocks each containing TDM metadata and a list of observation data lines.

At this level the observations are not Orekit objects but custom object containing a keyword (type of observation), a timetag (date of the observation) and a measurement (value of the observation).

It is up to the user to convert these observations to Orekit tracking object (Range, Angular, TurnAroundRange etc...).
