All Implemented Interfaces:

MessageParser<Omm>

public class OmmParser
extends OdmParser<Omm,OmmParser>

A parser for the CCSDS OMM (Orbiter Mean-Elements Message).

Note than starting with Orekit 11.0, CCSDS message parsers are mutable objects that gather the data being parsed, until the message is complete and the parseMessage method has returned. This implies that parsers should not be used in a multi-thread context. The recommended way to use parsers is to either dedicate one parser for each message and drop it afterwards, or to use a single-thread loop.

OmmParser

public OmmParser(IERSConventions conventions,

                 Function<ParseToken,List<ParseToken>>[] filters)

Complete constructor.

Calling this constructor directly is not recommended. Users should rather use parserBuilder.buildOmmParser().

Parameters:

conventions - IERS Conventions

simpleEOP - if true, tidal effects are ignored when interpolating EOP

dataContext - used to retrieve frames, time scales, etc.

missionReferenceDate - reference date for Mission Elapsed Time or Mission Relative Time time systems

mu - gravitational coefficient

defaultMass - default mass to use if there are no spacecraft parameters block logical block in the file

parsedUnitsBehavior - behavior to adopt for handling parsed units

filters - filters to apply to parse tokens

Since:

12.0
