different threads is allowed.

@DefaultDataContext public SP3Parser()
This constructor uses the default data context.
SP3Parser(double, int, Function)@DefaultDataContext public SP3Parser(double mu, int interpolationSamples, Function<? super String,? extends Frame> frameBuilder)
Propagator from the ephemeris data.
This constructor uses the default data context.
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.SP3Parser(double, int, Function, TimeScales)public SP3Parser(double mu,

This method creates a BufferedReader from the stream and as such this
method may read more data than necessary from stream and the additional
data will be lost. The other parse methods do not have this issue.

EphemerisFileParserFor Implementors: Most subclasses should implement this method as follows, but there is no default implementation because most subclasses should use a specialized return type.
try (BufferedReader reader = Files.newBufferedReader(Paths.get(fileName))) {
return parse(reader, fileName);
