Method Detail

generateEphemeris

public java.util.SortedSet generateEphemeris(double TS,
                                             double TF,
                                             double DELT)

Generates an ephemeris of OrbitalState instances between the given start and end times. The first (in terms of its timestamp) generated instance of OrbitalState always starts at the given start time, while the last will always be at or before the given end time.

Specified by:

generateEphemeris in interface Propagator

Parameters:

TS - Desired start of the ephemeris, in seconds since the epoch of the known orbital state.

TF - Desired end of the ephemeris, in seconds since the epoch of the known orbital state.

DELT - Desired time between the timestamps of the generated orbital states.

Returns:

A collection of zero or more instances of OrbitalState, sorted with respect to their timestamps.

Throws:

java.lang.IllegalArgumentException - DOCUMENT ME!
