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. It also uses a default number of samples to interpolate coordinates.

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.

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.
