org.orekit.files.ccsds.ndm.tdm.Tdm

public class Tdm
extends NdmConstituent<TdmHeader,Segment<TdmMetadata,ObservationsBlock>>

This class stores all the information of the CCSDS Tracking Data Message 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...).
