Package org.orekit.files.sp3

Class SP3Parser

java.lang.Object

org.orekit.files.sp3.SP3Parser

All Implemented Interfaces:

EphemerisFileParser<SP3>

public class SP3Parser
extends Object
implements EphemerisFileParser<SP3>

A parser for the SP3 orbit file format. It supports all formats from sp3-a to sp3-d.

Note: this parser is thread-safe, so calling parse(org.orekit.data.DataSource) from different threads is allowed.

Constructor Detail

SP3Parser

@DefaultDataContext
public SP3Parser()

Create an SP3 parser using default values.

This constructor uses the default data context.

SP3Parser(double, int, Function), IGSUtils.guessFrame(String)

SP3Parser

@DefaultDataContext
public SP3Parser(double mu,
                 int interpolationSamples,
                 Function<? super String,? extends Frame> frameBuilder)

Create an SP3 parser and specify the extra information needed to create a Propagator from the ephemeris data.

This constructor uses the default data context.

Parameters:

mu - is the standard gravitational parameter to use for creating Orbits from the ephemeris data. See Constants.

interpolationSamples - is the number of samples to use when interpolating.

frameBuilder - is a function that can construct a frame from an SP3 coordinate system string. The coordinate system can be any 5 character string e.g. ITR92, IGb08.

public SP3Parser(double mu,
                 int interpolationSamples,
                 Function<? super String,? extends Frame> frameBuilder,
                 TimeScales timeScales)

Create an SP3 parser and specify the extra information needed to create a Propagator from the ephemeris data.

Parameters:

mu - is the standard gravitational parameter to use for creating Orbits from the ephemeris data. See Constants.

interpolationSamples - is the number of samples to use when interpolating.

frameBuilder - is a function that can construct a frame from an SP3 coordinate system string. The coordinate system can be

timeScales - the set of time scales used for parsing dates.

10.1

Method Detail

guessFrame

@Deprecated
@DefaultDataContext
public static Frame guessFrame(String name)

Deprecated.

as of 12.1, replaced by IGSUtils.guessFrame(String)

Default string to Frame conversion for SP3Parser().

This method uses the default data context. If the frame names has a form like IGS##, or ITR##, or SLR##, where ## is a two digits number, then this number will be used to build the appropriate ITRFVersion. Otherwise (for example if name is UNDEF or WGS84), then a default ITRF will be created.

Parameters:

name - of the frame.

Returns:

ITRF based on 2010 conventions, with tidal effects considered during EOP interpolation

parse

public SP3 parse(DataSource source)

Description copied from interface: EphemerisFileParser

Parse an ephemeris file from a data source.

Specified by:

parse in interface EphemerisFileParser<SP3>

Parameters:

source - source providing the data to parse

Returns:

a parsed ephemeris file.
